Subject: [PATCH 004/788] [MTD] [NOR] Add support for flash chips with ID in
 bank other than 0

According to JEDEC "Standard Manufacturer's Identification Code"
(http://www.jedec.org/download/search/jep106W.pdf)
several first banks of NOR flash can contain 0x7f instead of actual ID.
This patch adds support for reading manufacturer ID from banks other than 0.

This patch add support for non-CFI Eon EN29SL800B[BT] NOR flash chips.
The Eon chips have manufacturer ID in the first bank, therefore this patch
depends on support for flash chips with ID in bank other than 0.

From 59018b6d2acabb114ab58637e6ab95ba424a89d0 Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@kernel.org>
Date: Tue, 20 May 2008 01:03:52 +0300
Subject: [PATCH 016/788] MTD/JFFS2: remove CVS keywords

Once upon a time, the MTD repository was using CVS.

This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.

This also includes code that printed them to the user.

Subject: [PATCH 018/788] [MTD] [MAPS] Blackfin Async Flash Maps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Handle the case where flash memory and ethernet mac/phy are mapped onto
the same async bank

[try #4]
 - drop superfluous casts
 - drop SSYNC() when reading from the flash and rewrite
   bfin_copy_from() to be like bfin_copy_to() so that
   we dont have to handle all the aligned/unaligned cases

[try #3] rename bf5xx-flash to bfin-async-flash
 - move all kconfig board settings into board resources
 - fixup casting style according to lkml feedback
 - rewrite driver so that it can handle arbitrary of
   instances according to the declared platform resources

[try #2]
Remove useless SSYNC() as Will said

[try #1]
The BF533-STAMP does this for example.
All board-specific configuration goes in your board resources file.

in reference from the function fsl_elbc_ctrl_probe() to the function

__devinit functions should not call functions with __devexit. Since probe
function calls remove in case of errors, we want to remove __devexit
attribute from it.

 names and Kconfig
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AT91 NAND driver needs just a few tiny modifications to work on
AVR32 as well. Rename it atmel_nand to reflect this.

Also move the ECC register definitions into drivers/mtd/nand since they
are only useful to the atmel_nand driver, and get rid of the useless
filename at the top of each file.

The board init code, typically running from postcore_initcall, may
need to set up SMC timings. We have to make sure the SMC driver is
ready before this happens.

The ATSTK1006 is basically an upgraded version of ATSTK1002 with
128 MiB SDRAM and 256 MiB NAND flash on board.

Otherwise, the board is very similar to the ATSTK1002, so it uses the
same board support file.

Subject: [PATCH 033/788] generic: per-device coherent dma allocator

Currently x86_32, sh and cris-v32 provide per-device coherent dma
memory allocator.

However their implementation is nearly identical. Refactor out
common code to be reused by them.

Subject: [PATCH 038/788] [MTD] [NAND] atmel_nand speedup via
 {read,write}s{b,w}()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This uses __raw_{read,write}s{b,w}() primitives to access data on NAND
chips for more efficient I/O.

On an arm926 with memory clocked at 100 MHz, this reduced the elapsed time
for a 64 MiB read by 16%.  ("dd" /dev/mtd0 to /dev/null, with an 8-bit
NAND using hardware ECC and 128KiB blocksize.)

Also some minor section tweaks:

  - Use platform_driver_probe() so no pointer to probe() lingers
    after that code has been removed at run-time.

  - Use __exit and __exit_p so the remove() code will normally be
    removed by the linker.

Since these buffer read/write calls are new, this increases the runtime
code footprint (by 88 bytes on my build, after the section tweaks).

The ALE signal isn't correctly wired up to the ECC controller on the

Work around this by resetting the ECC controller between the address and
data cycles.

Subject: [PATCH 041/788] [MTD] [NAND] fsl_elbc_nand: fix OOB workability for
 large page NAND chips

For large page chips, nand_bbt is looking into OOB area, and checking
for "0xff 0xff" pattern at OOB offset 0. That is, two bytes should be
reserved for bbt means.

But ELBC driver is specifying ecclayout so that oobfree area starts at
offset 1, so only one byte left for the bbt purposes.

This causes problems with any OOB users, namely JFFS2: after first mount
JFFS2 will fill all OOBs with "erased marker", so OOBs will contain:

  OOB Data: ff 19 85 20 03 00 ff ff ff 00 00 08 ff ff ff ff
  OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
  OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
  OOB Data: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff

And on the next boot, NAND core will rescan for bad blocks, then will
see "0xff 0x19" pattern, and will mark all blocks as bad ones.

To fix the issue we should implement our own bad block pattern: just one
byte at OOB start. Though, this will work only for x8 chips. For x16
chips two bytes must be checked. Since ELBC driver does not support x16
NANDs (yet), we're safe for now.

This patch implements support for flash-based BBT for chips working

for bad blocks on every boot.

Because ELBC controller may provide HW-generated ECCs we should adjust
bbt pattern and bbt version positions in the OOB free area.

From f63af11ddb508ce7b2a270515244d145248cad7f Mon Sep 17 00:00:00 2001
From: Milton Miller <miltonm@bga.com>
Date: Thu, 10 Jul 2008 16:14:18 -0500
Subject: [PATCH 045/788] [MTD] [NAND] remove __PPC__ hardcoded address from
 DiskOnChip drivers

Such a hardcoded address can cause a checkstop or machine check if
the driver is in the kernel but the address is not acknowledged.

Both drivers allow an address to be specified as either a module
parameter or config option.   Any future powerpc board should either
use one of these methods or find the address in the device tree.

Subject: [PATCH 051/788] Blackfin arch: Fix bug - Kernel does not boot if
 re-program clocks

Don't write conflicting data to EBIU_SDBCTL after the SDRAM is
configured. This can cause data corruption, since we might change SDRAM
row and column addressing modes.

Subject: [PATCH 056/788] firewire: fix race of bus reset with request
 transmission

Reported by Jay Fenlason:  A bus reset tasklet may call
fw_flush_transactions and touch transactions (call their callback which
will free them) while the context which submitted the transaction is
still inserting it into the transmission queue.

A simple solution to this problem is to _not_ "flush" the transactions
because of a bus reset (complete the transcations as 'cancelled').  They
will now simply time out (completed as 'cancelled' by the split-timeout
timer).

Jay Fenlason thought of this fix too but I was quicker to type it out.
:-)

Background:
Contexts which access an instance of struct fw_transaction are:
 1. the submitter, until it inserted the packet which is embedded in the
    transaction into the AT req DMA,
 2. the AsReqTrContext tasklet when the request packet was acked by the
    responder node or transmission to the responder failed,
 3. the AsRspRcvContext tasklet when it found a request which matched
    an incoming response,
 4. the card->flush_timer when it picks up timed-out transactions to
    cancel them,
 5. the bus reset tasklet when it cancels transactions (this access is
    eliminated by this patch),
 6. a process which shuts down an fw_card (unregisters it from fw-core
    when the controller is unbound from fw-ohci) --- although in this
    case there shouldn't really be any transactions anymore because we
    wait until all card users finished their business with the card.

All of these contexts run concurrently (except for the 6th, presumably).
The 1st is safe against the 2nd and 3rd because of the way how a request
packet is carefully submitted to the hardware.  A race between 2nd and
3rd has been fixed a while ago (bug 9617).  The 4th is almost safe
against 1st, 2nd, 3rd;  there are issues with it if huge scheduling
latencies occur, to be fixed separately.  The 5th looks safe against
2nd, 3rd, and 4th but is unsafe against 1st.  Maybe this could be fixed
with an explicit state variable in struct fw_transaction.  But this
would require fw_transaction to be rewritten as only dynamically
allocatable object with reference counting --- not a good solution if we
also can simply kill this 5th accessing context (replace it by the 4th).

Subject: [PATCH 057/788] firewire: fully initialize fw_transaction before
 marking it pending

In theory, card->flush_timer could already access a transaction between
fw_send_request()'s spin_unlock_irqrestore and the rest of what happens
in fw_send_request().  This would happen if the process which sends the
request is preempted and put to sleep right after spin_unlock_irqrestore
for longer than 100ms.

Therefore we fill in everything in struct fw_transaction at which the
flush_timer might look at before we lift the lock.

To do:  Ensure that the timer does not pick up the transaction before
the time of the AT request event plus split transaction timeout.

 removal

After card->done and card->work are completed, any remaining pending
request would be a bug.  We cannot safely complete a transaction at
that point anymore.

IOW card users must not drop their last fw_card reference (usually
indirect references through fw_device references) before their last
outbound transaction through that card was finished.

The fix in commit 3650925893469ccb03dbcc6a440c5d363350f591 was addressing
the case of a granted PR lock with waiting PR and CW locks.  It's a
special case that requires forcing a CW bast.  However, that forced CW
bast was incorrectly applying to a second condition where the granted
lock was CW.  So, the holder of a CW lock could receive an extraneous CW
bast instead of a PR bast.  This fix narrows the original special case to
what was intended.

Subject: [PATCH 073/788] ALSA: hda - Align BDL position adjustment parameter

It seems NVidia and other hardwares require the alignment for period
update timing.  For satisfying this condition, align the position
adjustment for delayed wake-up to the initial bdl_pos_adj value.

Subject: [PATCH 074/788] crypto: talitos - Remove calls to of_node_put

Remove of_node_put calls since there is no corresponding of_node_get.
This patch prevents an exception when talitos is loaded a 2nd time.
This sequence: modprobe talitos; rmmod talitos; modprobe talitos
causes this message: "WARNING: Bad of_node_put() on /soc8349@e0000000/crypto@30000".

Subject: [PATCH 077/788] crypto: talitos - Preempt overflow interrupts

add requests pending/submit count to prevent request queue full
condition by preempting h/w overflow interrupts in software.
We do this due to the delay in the delivery and handling of the
channel overflow error interrupt.

Subject: [PATCH 086/788] avr32: clean up mci platform code

This patch does a few small cleanups around the atmel mci platform code
and in the atmel-mci driver.  The platform changes simply removes an
unused variable, uses the fact that by the end we always have some form
of platform data and notes that GPIO_PIN_NONE != 0.  This last point
could cause the incorrect attempt to twice reserve pin PA0.

While we've got the hood up, add linux/err.h to the atmel-mci.c include
list.  It needs it and generally pulls it by voodoo but I did once
stumble across a config which don't build.

This is against Linus' latest git.

Things get weird between lockdep and ftrace because ftrace can be called
within lockdep internal code (via the mcount pointer) and lockdep can be
called with ftrace (via spin_locks).

Subject: [PATCH 091/788] ftrace: only trace preempt off with preempt tracer

When PREEMPT_TRACER and IRQSOFF_TRACER are both configured and irqsoff
tracer is running, the preempt_off sections might also be traced.

Thanks to Andrew Morton for pointing out my mistake of spin_lock disabling
interrupts while he was reviewing ftrace.txt. Seems that my example I used
actually hit this bug.

Subject: [PATCH 104/788] firewire: queue the right number of data

There will be 4 padding bytes in struct fw_cdev_event_response on some platforms
The member:__u32 data will point to these padding bytes. While queue the
response and data in complete_transaction in fw-cdev.c, it will queue like this:
|response(excluding padding bytes)|4 padding bytes|4 padding bytes|data.
It queue 4 extra bytes. That is to say it use "&response + sizeof(response)"
while other place of kernel and userspace library use "&response + offsetof
(typeof(response), data)". So it will lost the last 4 bytes of data. This patch
can fix it while not changing the struct definition.

Signed-off-by: JiSheng Zhang <jszhang3@mail.ustc.edu.cn>

This fixes responses to outbound block read requests on 64bit architectures.
Tested on i686, x86-64, and x86-64 with i686 userland, using firecontrol and
gscanbus.

this fixes typo in wm9712 codec which prevents it from registering all audio
routes (and thus working correctly). Please consider applying.

Subject: [PATCH 109/788] V4L/DVB (7736): This patch adds support for the
 Micronas DRX3975D/DRX3977D DVB-T demodulator

The module needs an external firmware file.

The module has been tested on a Pinnacle 330e, but with modules that
are currently not part of the linux-dvb tree. So consider this highly
experimental, don't use this code unless you are an experienced kernel
developer.

Subject: [PATCH 115/788] V4L/DVB (8423): cx18: remove firmware size check

This check was an ivtv leftover that served no purpose for the cx18.
Removed it, as this allows the user to load different firmware versions.

Subject: [PATCH 118/788] Input: serio - offload resume to kseriod

When resuming AUX ports psmouse driver calls psmouse_extensions()
to determine if the attached mouse is still the same, which may take
a while to complete for generic mice. Offload the resume process to
kseriod so the rest of the system may continue resuming without
waiting for the mouse.

Subject: [PATCH 120/788] lockdep: annotate cifs in-kernel sockets

Put CIFS sockets in their own class to avoid some lockdep warnings. CIFS
sockets are not exposed to user-space, and so are not subject to the
same deadlock scenarios.

A similar change was made a couple of years ago for RPC sockets in commit
ed07536ed6731775219c1df7fa26a7588753e693.

This patch should prevent lockdep false-positives like this one:

Subject: [PATCH 122/788] Input: ads7846 - optimize order of calculating Rt in
 ads7846_rx()

Alter the if expression for calculating Rt. The old implementation would
run unnecessary code when the ADS7843 device was used.

The patch also fixes the code style to kernel standard.

Subject: [PATCH 123/788] V4L/DVB (8427): videodev: split off the ioctl
 handling into v4l2-ioctl.c

videodev.c became top-heavy so all the ioctl processing has been split off
into v4l2-ioctl.c. This means videodev.c is back to its original purpose:
creating and registering v4l devices.

Since videodev.c and v4l2-ioctl.c should still remain one module (as least
for now) I also had to rename videodev.c to v4l2-dev.c to prevent a
circular dependency when building a videodev.ko module. This is not a bad
thing, since the source and header now have the same name. And the v4l2-
prefix is useful to see which sources are generic v4l2 support code.

From 5e85e732f0ed56aa97a3ba26ac2b93ffe597a208 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 20 Jul 2008 06:31:39 -0300
Subject: [PATCH 124/788] V4L/DVB (8428): videodev: rename 'dev' to 'parent'

The field 'dev' is not the video device, but the parent of the video device.
Rename accordingly.

From 22a04f106346c3af019135f2de3cabf9ac41c3ba Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 20 Jul 2008 06:35:02 -0300
Subject: [PATCH 125/788] V4L/DVB (8429): videodev: renamed 'class_dev' to
 'dev'

The class_dev field is a normal device, not a class device. This is very
confusing and now that the old 'dev' field has been renamed to 'parent'
we can rename 'class_dev' to just 'dev'.

Subject: [PATCH 126/788] V4L/DVB (8433): Fix macro name at z0194a.h

As reported by Hans Verkuil:

In file included from /home/v4l/master/v4l/dw2102.c:14:
/home/v4l/master/v4l/z0194a.h:93: error: 'STV0229_LOCKOUTPUT_1' undeclared here (not in a function)

This is due to some typos that were fixed on stv0299.

This patch renames it in accord with that fix.

Subject: [PATCH 127/788] [CIFS] break ATTR_SIZE changes out into their own
 function

Move the code that handles ATTR_SIZE changes to its own function. This
makes for a smaller function and reduces the level of indentation.

Subject: [PATCH 128/788] V4L/DVB (8430): videodev: move some functions from
 v4l2-dev.h to v4l2-common.h or v4l2-ioctl.h

The functions in a header should not belong to another module. The prio functions
belong to v4l2-common.c, so move them to v4l2-common.h.

The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header
and move those functions to it.

Subject: [PATCH 136/788] mmc_spi: put signals to low power off fix

The original intention was to write a zero byte to mmc to force spi
signals to low when doing power off. Somehow the spi_w8r8 call got there
so a read followed the write of single zero byte. This patch changes
that to simple write of zero byte without the following read.
This way the power off is more reliable and completely sufficient.

Subject: [PATCH 142/788] avr32: Add platform data for AC97C platform device

This patch adds platform data to the AC97C platform device. This will
let the board add a GPIO line which is connected to the external codecs
reset line.

The platform data, ac97c_platform_data, must also contain the DMA
controller ID, RX channel ID and TX channel ID.

Tested with Wolfson WM9712 and AP7000.

Subject: [PATCH 148/788] When verifying the decoded header before decoding the
 object identifier (expecting a SPNEGO pseudo-mechanism oid), the test to
 verify it is a primitive encoding is compared against the asn1 class. 
 Primitive is not a class.  This brings check in line with similar check for
 krb/ntlmssp oid.

Subject: [PATCH 153/788] RDMA/nes: CM connection setup/teardown rework

Major rework of CM connection setup/teardown.  We had a number of issues
with MPI applications not starting/terminating properly over time.
With these changes we were able to run longer on larger clusters.

* Remove memory allocation from nes_connect() and nes_cm_connect().
* Fix mini_cm_dec_refcnt_listen() when destroying listener.
* Remove unnecessary code from schedule_nes_timer() and nes_cm_timer_tick().
* Functionalize mini_cm_recv_pkt() and process_packet().
* Clean up cm_node->ref_count usage.

Subject: [PATCH 155/788] avr32: allow system timer to share interrupt to make
 OProfile work

The following patch allows the avr32_comparator interrupt to be shared.
This is necessary as the avr32 oprofile driver shares the irq group 0
with the timer.

To make OProfile actually work on AVR32, a small patch for oprofiled is
also needed (posted to the oprofile mailing list).

Subject: [PATCH 156/788] firewire: fw-ohci: TSB43AB22/A dualbuffer workaround

Isochronous reception in dualbuffer mode is reportedly broken with
TI TSB43AB22A on x86-64.  Descriptor addresses above 2G have been
determined as the trigger:
https://bugzilla.redhat.com/show_bug.cgi?id=435550

Two fixes are possible:
  - pci_set_consistent_dma_mask(pdev, DMA_31BIT_MASK);
    at least when IR descriptors are allocated, or
  - simply don't use dualbuffer.
This fix implements the latter workaround.

But we keep using dualbuffer on x86-32 which won't give us highmen (and
thus physical addresses outside the 31bit range) in coherent DMA memory
allocations.  Right now we could for example also whitelist PPC32, but
DMA mapping implementation details are expected to change there.

Subject: [PATCH 158/788] [MTD] [NOR] Fix -ETIMEO errors in CFI driver

Existing CFI driver has problems with excessive writes during erase.
If CFI driver does many writes during one erase cycle we may face the
messages with -ETIMEO error on erase operation.  It may cause the
following data corruption and kernel panics.

The reason of the issue is related to specifics of suspend operation:
if we write to flash during erase, suspend operation will cost some time
to erase procedure (for P30 it could be significant). In current version of
cfi driver the problem of many suspends is partially workarounded by adding
some time reserv to any operation (8xerase_time) but if we have many writes
during one erase the problem appears.

This patch detects the suspend and resets timer if suspend occured. It
has been well verified on different chips. No problems were found.
Could you please include the patch as it is simple and fixes bad issue.

Subject: [PATCH 161/788] [MTD][MTDPART] Seperate main loop from per-partition
 code in add_mtd_partition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

add_mtd_partition was a 150+ line monster consisting mostly of a single
loop.  Seperate the loop from most of the body.  Now it should be
obvious which variables are carried around from iteration to iteration.

Mostly simplifying the loops.  Now everything fits into 80 columns,
is easier to read and the finer details have extra comments.

Subject: [PATCH 165/788] [MTD] jedec_probe: Fix SST 16-bit chip detection

The unlock_addr rework in kernel 2.6.25 breaks 16-bit SST chips.  SST
39LF160 and SST 39VF1601 are both 16-bit only chip (do not have BYTE#
pin) and new uaddr value is not correct for them.  Add
MTD_UADDR_0xAAAA_0x5555 for those chips.  Tested with SST 39VF1601
chip.

Subject: [PATCH 168/788] [MTD] [NAND] subpage read feature as a way to
 increase performance.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch enables NAND subpage read functionality.
If upper layer drivers are requesting to read non page aligned data NAND
subpage-read functionality reads the only whose ECC regions which include
requested data when original code reads whole page.
This significantly improves performance in many cases.

Here are some digits :

UBI volume mount time
No subpage reads: 5.75 seconds
Subpage read patch: 2.42 seconds

Open/stat time for files on JFFS2 volume:
No subpage read  0m 5.36s
Subpage read     0m 2.88s

Subject: [PATCH 171/788] firewire: avoid memleak after phy config transmit
 failure

Use only statically allocated data for PHY config packet transmission.
With the previous incarnation, some data wouldn't be freed if the packet
transmit callback was never called.

A theoretical drawback now is that, in PCs with more than one card,
card A may complete() for a waiter on card B.  But this is highly
unlikely and its impact not serious.  Bus manager B may reset bus B
before the PHY config went out, but the next phy config on B should be
fine.  However, with a timeout of 100ms, this situation is close to
impossible.

Subject: [PATCH 174/788] kbuild: always unifdef files in headers_install*

unifdef utility is fast enough to warrant that we always
run the scripts through unifdef.

This patch runs all headers listed with header-y and unifdef-y
through unifdef.
Next step is to drop unifdef-y in all Kbuild files and
that can now be done in smaller steps.

Subject: [PATCH 175/788] kbuild: drop support of ALTARCH for headers_*

ALTARCH is no longer used by any arch(*) so drop
support for this from Makefile.headerinst

Dropping ALTARCH support simplifies Makefile.headerinst

(*) sparc64 uses it but work is ongoing to drop it
and no furter usage is planned.

Subject: [PATCH 178/788] kbuild: only one call for include/ in make headers_*

Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.

This revealed a long standing bug where "make headers_check_all"
relied on the files in asm/ for the current architecture.
So make headers_check_all is now broken by this commit.

In addition:

o add a simpler way to detect if an arch support
  exporting header files.

o add 'set -e;' so we error out early if
  make headers_check_all fails.

o add sparc64 and cris to arch we do not process
  in make headers_*_all because:

    sparc64 - use sparc to export headers
    cris    - is know seriously broken

Includes suggestions from: David Woodhouse
<dwmw2@infradead.org>.

From 7712401ae9006fc9d9b9a3e7861dc73781429a89 Mon Sep 17 00:00:00 2001

Subject: [PATCH 179/788] kbuild: optimize headers_* targets

Move the core functionality of headers_install
and headers_check to two small perl scripts.
The makefile is adapted to use the perl scrip and
changed to operate on all files in a directory.
So if one file is changed then all files in the
directory is processed.

perl were chosen for the helper scripts because this
is pure text processing which perl is good at and
especially the headers_check.pl script are expected to
see changes / new checks implmented.

The speed is ~300% faster on this box.
And the output generated to the screen is now down to
two lines per directory (one for install, one for check)
so it is easier to scroll back after a kernel build.

The perl scripts has been brought to sanity by patient
feedback from: Vegard Nossum <vegard.nossum@gmail.com>

Subject: [PATCH 180/788] kbuild: make clean removes *.o.* as well

Those are left presumably from aborted ccache(1) compilations:

	arch/x86/kernel/.tmp_io_apic_64.o.T5veul
	arch/x86/kvm/.tmp_x86.o.SZWn69
	arch/x86/mm/.tmp_pgtable.o.sL1LTf
	drivers/ieee1394/.tmp_ieee1394_transactions.o.bUj6o1
	drivers/infiniband/hw/mlx4/.tmp_main.o.vy0ep6

BTW, with git there is nice way to check for such nuisainces:

	make mrproper
	git-ls-files -o

should give empty output.

More precise wildcard spec from: Jan Engelhardt <jengelh@medozas.de>

Subject: [PATCH 181/788] kbuild: install all headers when arch is changed

We see some header files that are selected dependent on
the actual architecture so force a reinstallation
of all header files when the arch changes.
This slows down "make headers_check_all" but then
we better reflect reality.

Factor out the headers_*_all support to a seperate
shell script and add support for arch specific
header files can be located in either

    arch/$ARCH/include/asm
or
    include/asm-$ARCH/

In "make help" always display the headers_* targets.

Subject: [PATCH 184/788] kbuild: asm symlink support for arch/$ARCH/include

Adjust the asm symlink support so we do not create the
symlink unless really needed.
We check the precense of include/asm-$ARCH by checking
for the system.h file. We may end up with a stale directory
so it is not enough to check if the directory is present.

Subject: [PATCH 185/788] kbuild: add arch/$ARCH/include to search path

This patch conclude the support for

   arch/$ARCH/include

Note: The individual architectures will most likely require
      a few minor patches to support locating header files in
      arch/$ARCH/include

Testing shows that it worked out-of-the-box for sparc.
x86 required a few trivial changes in the arch
specific Makefile and a few include paths had to be adjusted.

Subject: [PATCH 187/788] vmlinux.lds: move __attribute__((__cold__)) functions
 back into final .text section

Due to the addition of __attribute__((__cold__)) to a few symbols
without adjusting the linker scripts, those symbols currently may end
up outside the [_stext,_etext) range, as they get placed in
.text.unlikely by (at least) gcc 4.3.0. This may confuse code not only
outside of the kernel, symbol_put_addr()'s BUG() could also trigger.
Hence we need to add .text.unlikely (and for future uses of
__attribute__((__hot__)) also .text.hot) to the TEXT_TEXT() macro.

Issue observed by Lukas Lipavsky.

Subject: [PATCH 189/788] kbuild: sparse needs CF not CHECKFLAGS

Documentation/sparse.txt tells to use:

    make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"

However, this still doesn't enable endian checks. The correct syntax is:

    make C=2 CF="-D__CHECK_ENDIAN__"

This documentation bug was introduced by the following commit:

    commit 1c7bafe7206d928eaccbcbd08d868733e0fb7054

This `typo' was not a typo, as `CF' had been introduced much earlier, by:

+
+Diffconfig is a simple utility for comparing two .config files.
+Using standard diff to compare .config files often includes extraneous and
+distracting information.  This utility produces sorted output with only the
+changes in configuration values between the two files.
+
+Added and removed items are shown with a leading plus or minus, respectively.
+Changed items show the old and new values on a single line.
+
+If -m is specified, then output will be in "merge" style, which has the
+changed and new values in kernel config option format.
+
+If no config files are specified, .config and .config.old are used.
+
+Example usage:
+ $ diffconfig .config config-with-some-changes
+-EXT2_FS_XATTR  n
+-EXT2_FS_XIP  n
+ CRAMFS  n -> y
+ EXT2_FS  y -> n
+ LOG_BUF_SHIFT  14 -> 16

Subject: [PATCH 193/788] kconfig: speed up all*config + randconfig

Drop the chatty mode when we generate the all*config, randconfig
configurations.
Ths speeds up the process considerably and noone looked
at the output anyway.
This patch uses the conf_set_all_new_symbols() function
just added to kconfig.

Subject: [PATCH 194/788] kconfig: make oldconfig is now less chatty

Previously when running "make oldconfig" we saw all the propmt lines
from kconfig and noone actully read this.

With this patch the user will only see output if there is new symbols.
This will be seen as "make oldconfig" runs which does not generate any output.

A typical run now looks like this:

$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
$

If a new symbol is found then we restart the config process like this:
$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
*
* Restart config...
*
*
* General setup
*
Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [Y/n/?] y
Local version - append to kernel release (LOCALVERSION) []
...

The bahaviour is similar to what we know when running the implicit
oldconfig target "make silentoldconfig".
"make silentoldconfig" are run as part of the kernel build process
if the configuration has changed.

Subject: [PATCH 195/788] kconfig: make defconfig is no longer chatty

make defconfig generated a lot of output
then noone actually read.
Use conf_set_all_new_symbols() to generate the default
configuration and avoid the chatty output.

A typical run now looks like this:
$ make  defconfig
*** Default configuration is based on 'i386_defconfig'
arch/x86/configs/i386_defconfig:13:warning: trying to assign nonexistent symbol SEMAPHORE_SLEEPERS
arch/x86/configs/i386_defconfig:176:warning: trying to assign nonexistent symbol PREEMPT_BKL
...
arch/x86/configs/i386_defconfig:1386:warning: trying to assign nonexistent symbol INSTRUMENTATION
$

As an added benefit we now clearly see the warnings generated
in the start of the process.

Subject: [PATCH 198/788] of: adapt of_find_i2c_driver() to be usable by SPI
 also

SPI has a similar problem as I2C in that it needs to determine an
appropriate modalias value for each device node.  This patch adapts
the of_i2c of_find_i2c_driver() function to be usable by of_spi also.

Subject: [PATCH 199/788] spi: split up spi_new_device() to allow two stage
 registration.

spi_new_device() allocates and registers an spi device all in one swoop.
If the driver needs to add extra data to the spi_device before it is
registered, then this causes problems.  This is needed for OF device
tree support so that the SPI device tree helper can add a pointer to
the device node after the device is allocated, but before the device
is registered.  OF aware SPI devices can then retrieve data out of the
device node to populate a platform data structure.

This patch splits the allocation and registration portions of code out
of spi_new_device() and creates two new functions; spi_alloc_device()
and spi_register_device().  spi_new_device() is modified to use the new
functions for allocation and registration.  None of the existing users
of spi_new_device() should be affected by this change.

Drivers using the new API can forego the use of spi_board_info
structure to describe the device layout and populate data into the
spi_device structure directly.

This change is in preparation for adding an OF device tree parser to
generate spi_devices based on data in the device tree.

This patch adds support for populating an SPI bus based on data in the
OF device tree.  This is useful for powerpc platforms which use the
device tree instead of discrete code for describing platform layout.

Subject: [PATCH 201/788] drivers/net: convert BUG_TRAP to generic WARN_ON
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removes legacy reinvent-the-wheel type thing. The generic
machinery integrates much better to automated debugging aids
such as kerneloops.org (and others), and is unambiguous due to
better naming. Non-intuively BUG_TRAP() is actually equal to
WARN_ON() rather than BUG_ON().

such as kerneloops.org (and others), and is unambiguous due to
better naming. Non-intuively BUG_TRAP() is actually equal to
WARN_ON() rather than BUG_ON() though some might actually be
promoted to BUG_ON() but I left that to future.

I could make at least one BUILD_BUG_ON conversion.

Subject: [PATCH 204/788] syncookies: Make sure ECN is disabled

ecn_ok is not initialized when a connection is established by cookies.
The cookie syn-ack never sets ECN, so ecn_ok must be set to 0.

Spotted using ns-3/network simulation cradle simulator and valgrind.

This reverts commit f867e6af94239a04ec23aeec2fcda5aa58e41db7.

Based upon discussions between Jarek and Patrick McHardy
this is field being set is more a config parameter than a
statistic.  And we should add a true statistic to provide
this information if we really want it.

Subject: [PATCH 211/788] dccp: Allow to distinguish original and retransmitted
 packets

This patch allows the sender to distinguish original and retransmitted packets,
which is in particular needed for the retransmission of DCCP-Requests:
 * the first Request uses ISS (generated in net/dccp/ip*.c), and sets GSS = ISS;
 * all retransmitted Requests use GSS' = GSS + 1, so that the n-th retransmitted
   Request has sequence number ISS + n (mod 48).

To add generic support, the patch reorganises existing code so that:
 * icsk_retransmits == 0     for the original packet and
 * icsk_retransmits = n > 0  for the n-th retransmitted packet
at the time dccp_transmit_skb() is called, via dccp_retransmit_skb().

Thanks to Wei Yongjun for pointing this problem out.

Further changes:
----------------
 * removed the `skb' argument from dccp_retransmit_skb(), since sk_send_head
   is used for all retransmissions (the exception is client-Acks in PARTOPEN
   state, but these do not use sk_send_head);
 * since sk_send_head always contains the original skb (via dccp_entail()),
   skb_cloned() never evaluated to true and thus pskb_copy() was never used.

Subject: [PATCH 212/788] dccp: Bug-Fix - AWL was never updated

The AWL lower Ack validity window advances in proportion to GSS, the greatest
sequence number sent. Updating AWL other than at connection setup (in the
DCCP-Request sent by dccp_v{4,6}_connect()) was missing in the DCCP code.

This bug lead to syslog messages such as

 "kernel: dccp_check_seqno: DCCP: Step 6 failed for DATAACK packet, [...]
  P.ackno exists or LAWL(82947089) <= P.ackno(82948208)
                                   <= S.AWH(82948728), sending SYNC..."

The difference between AWL/AWH here is 1639 packets, while the expected value
(the Sequence Window) would have been 100 (the default).  A closer look showed
that LAWL = AWL = 82947089 equalled the ISS on the Response.

The patch now updates AWL with each increase of GSS.


Further changes:
----------------
The patch also enforces more stringent checks on the ISS sequence number:

 * AWL is initialised to ISS at connection setup and remains at this value;
 * AWH is then always set to GSS (via dccp_update_gss());
 * so on the first Request: AWL =      AWH = ISS,
   and on the n-th Request: AWL = ISS, AWH = ISS + n.

As a consequence, only Response packets that refer to Requests sent by this
host will pass, all others are discarded. This is the intention and in effect
implements the initial adjustments for AWL as specified in RFC 4340, 7.5.1.

Subject: [PATCH 213/788] dccp: Fix sequence number check for ICMPv4 packets

The payload of ICMP message is a part of the packet sent by ourself,
so the sequence number check must use AWL and AWH, not SWL and SWH.

For example:
     Endpoint A                  Endpoint B

     DATA-ACK       -------->
     (SEQ=X)
                    <--------    ICMP (Fragmentation Needed)
                                 (SEQ=X)

Subject: [PATCH 215/788] dccp: Fix incorrect length check for ICMPv4 packets

Unlike TCP, which only needs 8 octets of original packet data, DCCP requires
minimally 12 or 16 bytes for ICMP-payload sequence number checks.

This patch replaces the insufficient length constant of 8 with a two-stage
test, making sure that 12 bytes are available, before computing the basic
header length required for sequence number checks.

Subject: [PATCH 219/788] ftrace: disable tracing on acpi idle calls

The acpi idle waits calls local_irq_save and then uses mwait to go into
idle. The tracer gets reenabled at local_irq_save but does not detect that
the idle allows for wake ups.

This patch adds code to disable the tracing when acpi puts the CPU to idle.

Subject: [PATCH 223/788] x86 gart: replace to_pages macro with iommu_num_pages

This patch removes the to_pages macro from x86 GART code and calls the generic
iommu_num_pages function instead.

Subject: [PATCH 228/788] cpumask: make cpumask_of_cpu_map generic

If an arch doesn't define cpumask_of_cpu_map, create a generic
statically-initialized one for them.  This allows removal of the buggy
cpumask_of_cpu() macro (&cpumask_of_cpu() gives address of
out-of-scope var).

An arch with NR_CPUS of 4096 probably wants to allocate this itself
based on the actual number of CPUs, since otherwise they're using 2MB
of rodata (1024 cpus means 128k).  That's what
CONFIG_HAVE_CPUMASK_OF_CPU_MAP is for (only x86/64 does so at the
moment).

In future as we support more CPUs, we'll need to resort to a
get_cpu_map()/put_cpu_map() allocation scheme.

Subject: [PATCH 229/788] cpumask: put cpumask_of_cpu_map in the initdata
 section

  * Create the cpumask_of_cpu_map statically in the init data section
    using NR_CPUS but replace it during boot up with one sized by
    nr_cpu_ids (num possible cpus).

Subject: [PATCH 230/788] cpumask: change cpumask_of_cpu_ptr to use new
 cpumask_of_cpu

  * Replace previous instances of the cpumask_of_cpu_ptr* macros
    with a the new (lvalue capable) generic cpumask_of_cpu().

Subject: [PATCH 235/788] V4L/DVB (8455): gspca_sonixb sn9c103 + ov7630
 autoexposure and cleanup

Andoni Zubimendi has been doing some testing with his sn9c103 cam with
ov7630 sensor, and with this patch the exposure setting and autoexposure now
work.

This patch also removes some special cases in the shared ov6650 / ov7630 code
which now are handled the same for both sensors and it adds a new special case
which stops us from changing the hsync / vsync polarity settings from their
default on the ov7630 (which we were doing as a side-effect of using the ov6650
exposure code for the ov7630).

Last this patch removes the superficial difference between the OV7630 and
OV7630_3 sensors.

Subject: [PATCH 239/788] V4L/DVB (8461): cx18: Fix 32 kHz audio sample output
 rate for analog tuner SIF input

cx18: Fix 32 kHz audio sample output rate for analog tuner SIF input so it
works.  The AUX_PLL VCO was being operated at 196.6 MHz out of the spec'ed
200-600 MHz range.  Fixed the multipler and post dividers to operate the VCO
within specification and added comments on how magic numbers are derived.

Thanks to Hans Verkuil for pointing out this interesting problem to solve.

Subject: [PATCH 240/788] V4L/DVB (8462): cx18: Lock the aux PLL to the video
 pixle rate for analog captures

cx18: Lock the aux PLL to the video pixel rate for analog captures.  The
datasheet for the CX25840 says this is important for MPEG encoding applications.
To ensure the PLL locking was correct, also fixed the aux PLL's multiplier to
be computed based on a precise crystal freq of 4.5 MHz/286 * 455/2 * 8 =
28636363.6363... instead of the imporperly rounded 28636363.

 /dev/video0 and /dev/video1

With the HVR1800, trying to use video0 and video1 simultaneously caused
buffer corruption in the PCIe bridge. This fix reallocates video1
buffer locations to avoid the issue.

Subject: [PATCH 249/788] V4L/DVB (8472): cx23885: SRAM changes for the 885 and
 887 silicon parts.

In a previous patch I merged both memory maps into a single struct, believing
that they could be combined. We've since found problems with streaming
multiple channels on the 885. I'm restoring the multiple memory map structs
- in line with the windows driver.

Subject: [PATCH 250/788] V4L/DVB (8474): pvrusb2: Enable IR chip on HVR-1900
 class devices

The Zilog IR chip on HVR-1900 devices is held in reset when the device
initializes.  We have to bring this chip out of reset before LIRC has
any chance of operating the chip.  So do it.

Subject: [PATCH 253/788] V4L/DVB (8479): tveeprom/ivtv: fix usage of has_ir
 field

has_ir was set to and compared to -1 in several cases, even though it is
an u32. ivtv also contained a FIXME for an old kernel that could be
removed.

Thanks to Roel Kluin for creating an initial patch for this. Although
I chose a different solution here it did help in pointing out the problem.

Subject: [PATCH 254/788] V4L/DVB (8482): videodev: move all ioctl callbacks to
 a new v4l2_ioctl_ops struct

All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in
a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it.

This ensures a clean separation between the const ops struct and the non-const
video_device struct.

From 9c39d7eafa366b807067697f7fc5b14d8b865179 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Mon, 21 Jul 2008 07:51:45 -0300
Subject: [PATCH 255/788] V4L/DVB (8483): Remove obsolete owner field from
 video_device struct.

According to an old comment this should have been removed in 2.6.15.
Better late than never...

The PlanB driver has been broken since around May 2004. No one stepped
in to maintain it, so it is now being removed.

From 33b687cf1df62bd83167616516922b4e472be662 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Fri, 25 Jul 2008 05:32:50 -0300
Subject: [PATCH 258/788] V4L/DVB (8487): videodev: replace videodev.h includes
 by videodev2.h where possible

Several V4L2 drivers still included videodev.h. Fix this.

From f894dfd735237548d282d6fd55b6ebb4b2fd9ef2 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Fri, 25 Jul 2008 07:39:54 -0300
Subject: [PATCH 260/788] V4L/DVB (8488): videodev: remove some
 CONFIG_VIDEO_V4L1_COMPAT code from v4l2-dev.h

The video_device_create_file and video_device_remove_file functions can be
removed from v4l2-dev.h, removing the dependency on videodev.h in v4l2-dev.h.

Also removed a few more videodev.h includes that should have been videodev2.h.

Subject: [PATCH 262/788] V4L/DVB (8490): s2255drv Sensoray 2255 driver fixes

This patch fixes timer issues in driver disconnect.
It also removes the restriction of one user per channel at a time.

Thanks to Oliver Neukum and Mauro Chehab for finding these issues.
Locking of video stream partly based on saa7134 driver.

Subject: [PATCH 263/788] V4L/DVB (8491): stkwebcam: Always reuse last queued
 buffer

This change keeps the video stream going on when the application
is slow queuing buffers, instead of spamming dmesg and hanging.

Fixes a problem with aMSN reported by Samed Beyribey <beyribey@gmail.com>

Subject: [PATCH 268/788] V4L/DVB (8496): saa7134: Copy tuner data earlier in
 init to avoid overwriting manual tuner type

When saa7134_board_init2 runs, it immediately overwrites the current value
(set earlier from module parameter) of tuner_type with the static values,
and then does autodetection. This patch moves the tuner_addr copy to earlier
in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2.

Autodetection could still potentially change to the wrong tuner type, but it
is now possible to override the default type for the card again.

My card's tuner is configured with autodetection from eeprom, so I don't
need to manually set the tuner. I've checked that the autodetection still
works for my card.

to set the bounds to 0 and 1 for boolean controls instead of returning
uninitialized values.

Subject: [PATCH 271/788] V4L/DVB (8499): zr36067: Rework device memory
 allocation

Allocate zoran devices dynamically. Currently, the zr36067 driver
stores the device structures in a global array, with room for 4
devices. This makes the bss section very large (90 kB!), and given
that most users, I suspect, have only one zoran device, this is a
waste of kernel memory. Allocating the memory dynamically lets us use
only the amount of memory we need.

Subject: [PATCH 283/788] pnp: set the pnp_card dma_mask for use by ISAPnP
 cards

dma_alloc_coherent() on x86 currently takes a passed in NULL device
pointer to mean that it should allocate an ISA compatible (24-bit) buffer
which is a bit of a hack.

The ALSA ISA drivers are the main consumers of this but have a struct
device in fact readily available.

For the PnP drivers, the specific pnp_dev->dev device pointer is not
always available at the right time so for now we want to pass the
pnp_card->dev instead which is always available.  Set its dma_mask in
preparation for doing so.

This does not fix a current bug -- 2.6.26-rc1 stumbled over the NULL hack
in dma_alloc_coherent() but this has already been fixed in commit
4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.

using the actual device with the DMA API so as to eventually not need the
NULL hack in dma_alloc_coherent().

This does not fix a current bug -- 2.6.26-rc1 stumbled over the NULL hack
in dma_alloc_coherent() but this has already been fixed in commit
4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.

Subject: [PATCH 285/788] pnp: have quirk_system_pci_resources() include io
 resources

quirk_system_pci_resources() disables a PnP mem resource that overlaps a
PCI BAR so as to not keep the PCI driver from claiming the resource.  Have
it do the same for io resources.

Here, ACPI claims ports that overlap with my soundcard causing the
soundcard driver to fail to load.  It's unknown why my ACPI BIOS claims
those ports; it did not use to but this is not a (kernel) regression.
Some odd BIOS reconfig triggered by temporarily removing the card seems to
have brought this on.

Fix the fcpnp_driver declaration to only exist if CONFIG_PNP=y as it's
only accessed in that case.

The PNP=n variant was added by 30d55e71a81b1f5a8136f191dc9f4c21f18e77e6
("hisax: depend on CONFIG_PNP, not __ISAPNP__")

Fixes an unused variable warning.

Subject: [PATCH 287/788] dma-mapping: add the device argument to
 dma_mapping_error()

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
architecture does:

This enables us to cleanly fix the Calgary IOMMU issue that some devices
are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).

I think that per-device dma_mapping_ops support would be also helpful for
KVM people to support PCI passthrough but Andi thinks that this makes it
difficult to support the PCI passthrough (see the above thread).  So I
CC'ed this to KVM camp.  Comments are appreciated.

A pointer to dma_mapping_ops to struct dev_archdata is added.  If the
pointer is non NULL, DMA operations in asm/dma-mapping.h use it.  If it's
NULL, the system-wide dma_ops pointer is used as before.

If it's useful for KVM people, I plan to implement a mechanism to register
a hook called when a new pci (or dma capable) device is created (it works
with hot plugging).  It enables IOMMUs to set up an appropriate
dma_mapping_ops per device.

The major obstacle is that dma_mapping_error doesn't take a pointer to the
device unlike other DMA operations.  So x86 can't have dma_mapping_ops per
device.  Note all the POWER IOMMUs use the same dma_mapping_error function
so this is not a problem for POWER but x86 IOMMUs use different
dma_mapping_error functions.

The first patch adds the device argument to dma_mapping_error.  The patch
is trivial but large since it touches lots of drivers and dma-mapping.h in
all the architecture.

This patch:

dma_mapping_error() doesn't take a pointer to the device unlike other DMA
operations.  So we can't have dma_mapping_ops per device.

Note that POWER already has dma_mapping_ops per device but all the POWER
IOMMUs use the same dma_mapping_error function.  x86 IOMMUs use device
argument.

From 1956a96de488feb05e95c08c9d5e80f63a4be2b1 Mon Sep 17 00:00:00 2001
From: Alexis Bruemmer <alexisb@us.ibm.com>
Date: Fri, 25 Jul 2008 19:44:51 -0700
Subject: [PATCH 288/788] x86 calgary: fix handling of devices that aren't
 behind the Calgary

The calgary code can give drivers addresses above 4GB which is very bad
for hardware that is only 32bit DMA addressable.

With this patch, the calgary code sets the global dma_ops to swiotlb or
nommu properly, and the dma_ops of devices behind the Calgary/CalIOC2
to calgary_dma_ops.  So the calgary code can handle devices safely that
aren't behind the Calgary/CalIOC2.

Subject: [PATCH 294/788] parport_pc: add base_hi BAR for oxsemi_840

Use the 2nd BAR for the oxsemi_840 chip as BAR for base_hi.  Tested with:

Parallel controller [0701]: Oxford Semiconductor Ltd VScom 011H-EP1
        1 port parallel adaptor [1415:8403] (prog-if 03 [IEEE1284])

This patch is needed to make 'TRISTATE' work with that adaptor.

Subject: [PATCH 297/788] tpm: increase size of internal TPM response buffers

This patch increases size of driver internal response buffers.  Some TPM
responses defined in TCG TPM Specification Version 1.2 Revision 103 have
increased size and do not fit previously defined buffers.  Some TPM
responses do not have fixed size, so bigger response buffers have to be
allocated.  200B buffers should be enough.

Subject: [PATCH 298/788] tpm: Use correct data types for sizes in tpm_write()

Use the correct data types for the size parameters in tpm_write() and
tpm_read(). Note that rw_verify_area() makes sure that this bug cannot
be exploited to produce a buffer overrun.

Subject: [PATCH 299/788] memstick: allow "set_param" method to return an error
 code

Some controllers (Jmicron, for instance) can report temporal failure
condition during power-on.  It is desirable to account for this using a
return value of "set_param" device method.  The return value can also be
handy to distinguish between supported and unsupported device parameters
in run time.

In some cases it may be desirable to ensure that associated driver is not
going to access the media in some period of time.  "start" and "stop"
methods are provided therefore to allow it.

Subject: [PATCH 303/788] kexec jump

This patch provides an enhancement to kexec/kdump.  It implements the
following features:

- Backup/restore memory used by the original kernel before/after
  kexec.

- Save/restore CPU state before/after kexec.

The features of this patch can be used as a general method to call program in
physical mode (paging turning off).  This can be used to call BIOS code under
Linux.

kexec-tools needs to be patched to support kexec jump. The patches and
the precompiled kexec can be download from the following URL:

       source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2
       patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2
       binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10

Usage example of calling some physical mode code and return:

1. Compile and install patched kernel with following options selected:

CONFIG_X86_32=y
CONFIG_KEXEC=y
CONFIG_PM=y
CONFIG_KEXEC_JUMP=y

2. Build patched kexec-tool or download the pre-built one.

3. Build some physical mode executable named such as "phy_mode"

4. Boot kernel compiled in step 1.

5. Load physical mode executable with /sbin/kexec. The shell command
   line can be as follow:

   /sbin/kexec --load-preserve-context --args-none phy_mode

6. Call physical mode executable with following shell command line:

   /sbin/kexec -e

Implementation point:

To support jumping without reserving memory.  One shadow backup page (source
page) is allocated for each page used by kexeced code image (destination
page).  When do kexec_load, the image of kexeced code is loaded into source
pages, and before executing, the destination pages and the source pages are
swapped, so the contents of destination pages are backupped.  Before jumping
to the kexeced code image and after jumping back to the original kernel, the
destination pages and the source pages are swapped too.

C ABI (calling convention) is used as communication protocol between
kernel and called code.

A flag named KEXEC_PRESERVE_CONTEXT for sys_kexec_load is added to
indicate that the loaded kernel image is used for jumping back.

Now, only the i386 architecture is supported.

Subject: [PATCH 304/788] kexec jump: save/restore device state

This patch implements devices state save/restore before after kexec.

This patch together with features in kexec_jump patch can be used for
following:

- A simple hibernation implementation without ACPI support.  You can kexec a
  hibernating kernel, save the memory image of original system and shutdown
  the system.  When resuming, you restore the memory image of original system
  via ordinary kexec load then jump back.

- Kernel/system debug through making system snapshot.  You can make system
  snapshot, jump back, do some thing and make another system snapshot.

- Cooperative multi-kernel/system.  With kexec jump, you can switch between
  several kernels/systems quickly without boot process except the first time.
  This appears like swap a whole kernel/system out/in.

- A general method to call program in physical mode (paging turning
  off). This can be used to invoke BIOS code under Linux.

The following user-space tools can be used with kexec jump:

- kexec-tools needs to be patched to support kexec jump. The patches
  and the precompiled kexec can be download from the following URL:
       source: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-src_git_kh10.tar.bz2
       patches: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec-tools-patches_git_kh10.tar.bz2
       binary: http://khibernation.sourceforge.net/download/release_v10/kexec-tools/kexec_git_kh10

- makedumpfile with patches are used as memory image saving tool, it
  can exclude free pages from original kernel memory image file. The
  patches and the precompiled makedumpfile can be download from the
  following URL:
       source: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-src_cvs_kh10.tar.bz2
       patches: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile-patches_cvs_kh10.tar.bz2
       binary: http://khibernation.sourceforge.net/download/release_v10/makedumpfile/makedumpfile_cvs_kh10

- An initramfs image can be used as the root file system of kexeced
  kernel. An initramfs image built with "BuildRoot" can be downloaded
  from the following URL:
       initramfs image: http://khibernation.sourceforge.net/download/release_v10/initramfs/rootfs_cvs_kh10.gz
  All user space tools above are included in the initramfs image.

Usage example of simple hibernation:

1. Compile and install patched kernel with following options selected:

CONFIG_X86_32=y
CONFIG_RELOCATABLE=y
CONFIG_KEXEC=y
CONFIG_CRASH_DUMP=y
CONFIG_PM=y
CONFIG_HIBERNATION=y
CONFIG_KEXEC_JUMP=y

2. Build an initramfs image contains kexec-tool and makedumpfile, or
   download the pre-built initramfs image, called rootfs.gz in
   following text.

3. Prepare a partition to save memory image of original kernel, called
   hibernating partition in following text.

4. Boot kernel compiled in step 1 (kernel A).

5. In the kernel A, load kernel compiled in step 1 (kernel B) with
   /sbin/kexec. The shell command line can be as follow:

   /sbin/kexec --load-preserve-context /boot/bzImage --mem-min=0x100000
     --mem-max=0xffffff --initrd=rootfs.gz

6. Boot the kernel B with following shell command line:

   /sbin/kexec -e

7. The kernel B will boot as normal kexec. In kernel B the memory
   image of kernel A can be saved into hibernating partition as
   follow:

   jump_back_entry=`cat /proc/cmdline | tr ' ' '\n' | grep kexec_jump_back_entry | cut -d '='`
   echo $jump_back_entry > kexec_jump_back_entry
   cp /proc/vmcore dump.elf

   Then you can shutdown the machine as normal.

8. Boot kernel compiled in step 1 (kernel C). Use the rootfs.gz as
   root file system.

9. In kernel C, load the memory image of kernel A as follow:

   /sbin/kexec -l --args-none --entry=`cat kexec_jump_back_entry` dump.elf

10. Jump back to the kernel A as follow:

   /sbin/kexec -e

   Then, kernel A is resumed.

Implementation point:

To support jumping between two kernels, before jumping to (executing)
the new kernel and jumping back to the original kernel, the devices
are put into quiescent state, and the state of devices and CPU is
saved. After jumping back from kexeced kernel and jumping to the new
kernel, the state of devices and CPU are restored accordingly. The
devices/CPU state save/restore code of software suspend is called to
implement corresponding function.

Known issues:

- Because the segment number supported by sys_kexec_load is limited,
  hibernation image with many segments may not be load. This is
  planned to be eliminated by adding a new flag to sys_kexec_load to
  make a image can be loaded with multiple sys_kexec_load invoking.

Now, only the i386 architecture is supported.

Subject: [PATCH 305/788] Better interface for hooking early initcalls

Added early initcall (pre-SMP) support, using an identical interface to
that of regular initcalls.  Functions called from do_pre_smp_initcalls()
could be converted to use this cleaner interface.

This is required by CPU hotplug, because early users have to register
notifiers before going SMP.  One such CPU hotplug user is the relay
interface with buffer-only channels, which needs to register such a
notifier, to be usable in early code.  This in turn is used by kmemtrace.

Subject: [PATCH 307/788] relay: add buffer-only channels; useful for early
 logging

Allows one to create and use a channel with no associated files.  Files
can be initialized later.  This is useful in scenarios such as logging in
early code, before VFS is up.  Therefore, such channels can be created and
used as soon as kmem_cache_init() completed.

This is needed by kmemtrace to do tracing in early kernel code.

+Buffer-only channels
+--------------------
+
+These channels have no files associated and can be created with
+relay_open(NULL, NULL, ...). Such channels are useful in scenarios such
+as when doing early tracing in the kernel, before the VFS is up. In these
+cases, one may open a buffer-only channel and then call

Subject: [PATCH 309/788] omfs: add filesystem documentation

These patches add the Optimized MPEG Filesystem, a proprietary filesystem used
by the embedded devices Rio Karma and ReplayTV, which are no longer
manufactured.  This filesystem module enables people to access files on these
devices.

This patch:

OMFS is a proprietary filesystem created for the ReplayTV and also used by the
Rio Karma.  It uses hash tables with unordered, unbounded lists in each bucket
for directories, extents for data blocks, 64-bit addressing for blocks, with
up to 8K blocks (only 2K of a given block is ever used for metadata, so the FS
still works with 4K pages).

Document the filesystem usage and structures.

+Optimized MPEG Filesystem (OMFS)
+
+Overview
+========
+
+OMFS is a filesystem created by SonicBlue for use in the ReplayTV DVR
+and Rio Karma MP3 player.  The filesystem is extent-based, utilizing
+block sizes from 2k to 8k, with hash-based directories.  This
+filesystem driver may be used to read and write disks from these
+devices.
+
+Note, it is not recommended that this FS be used in place of a general
+filesystem for your own streaming media device.  Native Linux filesystems
+will likely perform better.
+
+More information is available at:
+
+    http://linux-karma.sf.net/
+
+Various utilities, including mkomfs and omfsck, are included with
+omfsprogs, available at:
+
+    http://bobcopeland.com/karma/
+
+Instructions are included in its README.
+
+Options
+=======
+
+OMFS supports the following mount-time options:
+
+    uid=n        - make all files owned by specified user
+    gid=n        - make all files owned by specified group
+    umask=xxx    - set permission umask to xxx
+    fmask=xxx    - set umask to xxx for files
+    dmask=xxx    - set umask to xxx for directories
+
+Disk format
+===========
+
+OMFS discriminates between "sysblocks" and normal data blocks.  The sysblock
+group consists of super block information, file metadata, directory structures,
+and extents.  Each sysblock has a header containing CRCs of the entire
+sysblock, and may be mirrored in successive blocks on the disk.  A sysblock may
+have a smaller size than a data block, but since they are both addressed by the
+same 64-bit block number, any remaining space in the smaller sysblock is
+unused.
+
+Sysblock header information:
+
+struct omfs_header {
+        __be64 h_self;                  /* FS block where this is located */
+        __be32 h_body_size;             /* size of useful data after header */
+        __be16 h_crc;                   /* crc-ccitt of body_size bytes */
+        char h_fill1[2];
+        u8 h_version;                   /* version, always 1 */
+        char h_type;                    /* OMFS_INODE_X */
+        u8 h_magic;                     /* OMFS_IMAGIC */
+        u8 h_check_xor;                 /* XOR of header bytes before this */
+        __be32 h_fill2;
+};
+
+Files and directories are both represented by omfs_inode:
+
+struct omfs_inode {
+        struct omfs_header i_head;      /* header */
+        __be64 i_parent;                /* parent containing this inode */
+        __be64 i_sibling;               /* next inode in hash bucket */
+        __be64 i_ctime;                 /* ctime, in milliseconds */

+};
+
+Directories in OMFS are implemented as a large hash table.  Filenames are
+hashed then prepended into the bucket list beginning at OMFS_DIR_START.
+Lookup requires hashing the filename, then seeking across i_sibling pointers
+until a match is found on i_name.  Empty buckets are represented by block
+pointers with all-1s (~0).
+
+A file is an omfs_inode structure followed by an extent table beginning at
+OMFS_EXTENT_START:
+
+struct omfs_extent_entry {
+        __be64 e_cluster;               /* start location of a set of blocks */
+        __be64 e_blocks;                /* number of blocks after e_cluster */
+};
+
+struct omfs_extent {
+        __be64 e_next;                  /* next extent table location */
+        __be32 e_extent_count;          /* total # extents in this table */
+        __be32 e_fill;
+        struct omfs_extent_entry e_entry;       /* start of extent entries */
+};
+
+Each extent holds the block offset followed by number of blocks allocated to
+the extent.  The final extent in each table is a terminator with e_cluster
+being ~0 and e_blocks being ones'-complement of the total number of blocks
+in the table.
+
+If this table overflows, a continuation inode is written and pointed to by
+e_next.  These have a header but lack the rest of the inode structure.

From: Bob Copeland <me@bobcopeland.com>
Date: Fri, 25 Jul 2008 19:45:16 -0700
Subject: [PATCH 312/788] omfs: add directory routines

Add lookup and directory management routines for OMFS.  The filesystem uses
hashing based on the filename and stores collisions, unordered, in siblings
of files' inode structures.  To support telldir, the current position in
the hash table is encoded in fpos.

Subject: [PATCH 320/788] x86: implement pte_special

Implement the pte_special bit for x86.  This is required to support
lockless get_user_pages, because we need to know whether or not we can
refcount a particular page given only its pte (and no vma).

Subject: [PATCH 321/788] mm: introduce get_user_pages_fast

Introduce a new get_user_pages_fast mm API, which is basically a
get_user_pages with a less general API (but still tends to be suited to
the common case):

- task and mm are always current and current->mm
- force is always 0
- pages is always non-NULL
- don't pass back vmas

This restricted API can be implemented in a much more scalable way on many
architectures when the ptes are present, by walking the page tables
locklessly (no mmap_sem or page table locks).  When the ptes are not
populated, get_user_pages_fast() could be slower.

This is implemented locklessly on x86, and used in some key direct IO call
sites, in later patches, which provides nearly 10% performance improvement
on a threaded database workload.

Lots of other code could use this too, depending on use cases (eg.  grep
drivers/).  And it might inspire some new and clever ways to use it.

Subject: [PATCH 322/788] x86: lockless get_user_pages_fast()

Implement get_user_pages_fast without locking in the fastpath on x86.

Do an optimistic lockless pagetable walk, without taking mmap_sem or any
page table locks or even mmap_sem.  Page table existence is guaranteed by
turning interrupts off (combined with the fact that we're always looking
up the current mm, means we can do the lockless page table walk within the
constraints of the TLB shootdown design).  Basically we can do this
lockless pagetable walk in a similar manner to the way the CPU's pagetable
walker does not have to take any locks to find present ptes.

This patch (combined with the subsequent ones to convert direct IO to use
it) was found to give about 10% performance improvement on a 2 socket 8
core Intel Xeon system running an OLTP workload on DB2 v9.5

 "To test the effects of the patch, an OLTP workload was run on an IBM
  x3850 M2 server with 2 processors (quad-core Intel Xeon processors at
  2.93 GHz) using IBM DB2 v9.5 running Linux 2.6.24rc7 kernel.  Comparing
  runs with and without the patch resulted in an overall performance
  benefit of ~9.8%.  Correspondingly, oprofiles showed that samples from
  __up_read and __down_read routines that is seen during thread contention
  for system resources was reduced from 2.8% down to .05%.  Monitoring the
  /proc/vmstat output from the patched run showed that the counter for
  fast_gup contained a very high number while the fast_gup_slow value was
  zero."

(fast_gup is the old name for get_user_pages_fast, fast_gup_slow is a
counter we had for the number of times the slowpath was invoked).

The main reason for the improvement is that DB2 has multiple threads each
issuing direct-IO.  Direct-IO uses get_user_pages, and thus the threads
contend the mmap_sem cacheline, and can also contend on page table locks.

I would anticipate larger performance gains on larger systems, however I
think DB2 uses an adaptive mix of threads and processes, so it could be
that thread contention remains pretty constant as machine size increases.
In which case, we stuck with "only" a 10% gain.

The downside of using get_user_pages_fast is that if there is not a pte
with the correct permissions for the access, we end up falling back to
get_user_pages and so the get_user_pages_fast is a bit of extra work.
However this should not be the common case in most performance critical
code.

Subject: [PATCH 324/788] splice: use get_user_pages_fast

Use get_user_pages_fast in splice.  This reverts some mmap_sem batching
there, however the biggest problem with mmap_sem tends to be hold times
blocking out other threads rather than cacheline bouncing.  Further: on
architectures that implement get_user_pages_fast without locks, mmap_sem
can be avoided completely anyway.

Subject: [PATCH 326/788] mm: readahead scan lockless

radix_tree_next_hole() is implemented as a series of radix_tree_lookup()s.
So it can be called locklessly, under rcu_read_lock().

Subject: [PATCH 328/788] mm: speculative page references

If we can be sure that elevating the page_count on a pagecache page will
pin it, we can speculatively run this operation, and subsequently check to
see if we hit the right page rather than relying on holding a lock or
otherwise pinning a reference to the page.

This can be done if get_page/put_page behaves consistently throughout the
whole tree (ie.  if we "get" the page after it has been used for something
else, we must be able to free it with a put_page).

Actually, there is a period where the count behaves differently: when the
page is free or if it is a constituent page of a compound page.  We need
an atomic_inc_not_zero operation to ensure we don't try to grab the page
in either case.

This patch introduces the core locking protocol to the pagecache (ie.
adds page_cache_get_speculative, and tweaks some update-side code to make
it work).

Thanks to Hugh for pointing out an improvement to the algorithm setting
page_count to zero when we have control of all references, in order to
hold off speculative getters.

From a60637c85893e7191faaafa6a72e197c24386727 Mon Sep 17 00:00:00 2001
From: Nick Piggin <npiggin@suse.de>
Date: Fri, 25 Jul 2008 19:45:31 -0700
Subject: [PATCH 329/788] mm: lockless pagecache

Combine page_cache_get_speculative with lockless radix tree lookups to
introduce lockless page cache lookups (ie.  no mapping->tree_lock on the
read-side).

The only atomicity changes this introduces is that the gang pagecache
lookup functions now behave as if they are implemented with multiple
find_get_page calls, rather than operating on a snapshot of the pages.  In
practice, this atomicity guarantee is not used anyway, and it is to
replace individual lookups, so these semantics are natural.

Subject: [PATCH 332/788] SL*B: drop kmem cache argument from constructor

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres.  Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.

Non-trivial places are:
	arch/powerpc/mm/init_64.c
	arch/powerpc/mm/hugetlbpage.c

This is flag day, yes.

Subject: [PATCH 333/788] Use WARN() in kernel/irq/manage.c

Replace a printk+WARN_ON() by a WARN(); this increases the chance of the
string making it into the bugreport (ie: it goes inside the
---[ cut here ]--- section)

Subject: [PATCH 342/788] tracehook: add linux/tracehook.h

This patch series introduces the "tracehook" interface layer of inlines in
<linux/tracehook.h>.  There are more details in the log entry for patch
01/23 and in the header file comments inside that patch.  Most of these
changes move code around with little or no change, and they should not
break anything or change any behavior.

This sets a new standard for uniform arch support to enable clean
arch-independent implementations of new debugging and tracing stuff,
denoted by CONFIG_HAVE_ARCH_TRACEHOOK.  Patch 20/23 adds that symbol to
arch/Kconfig, with comments listing everything an arch has to do before
setting "select HAVE_ARCH_TRACEHOOK".  These are elaborted a bit at:

	http://sourceware.org/systemtap/wiki/utrace/arch/HowTo

The new inlines that arch code must define or call have detailed kerneldoc
comments in the generic header files that say what is required.

No arch is obligated to do any work, and no arch's build should be broken
by these changes.  There are several steps that each arch should take so
it can set HAVE_ARCH_TRACEHOOK.  Most of these are simple.  Providing this
support will let new things people add for doing debugging and tracing of
user-level threads "just work" for your arch in the future.  For an arch
that does not provide HAVE_ARCH_TRACEHOOK, some new options for such
features will not be available for config.

I have done some arch work and will submit this to the arch maintainers
after the generic tracehook series settles in.  For now, that work is
available in my GIT repositories, and in patch and mbox-of-patches form at
http://people.redhat.com/roland/utrace/2.6-current/

This paves the way for my "utrace" work, to be submitted later.  But it is
not innately tied to that.  I hope that the tracehook series can go in
soon regardless of what eventually does or doesn't go on top of it.  For
anyone implementing any kind of new tracing/debugging plan, or just
understanding all the context of the existing ptrace implementation,
having tracehook.h makes things much easier to find and understand.

This patch:

This adds the new kernel-internal header file <linux/tracehook.h>.  This
is not yet used at all.  The comments in the header introduce what the
following series of patches is about.

The aim is to formalize and consolidate all the places that the core
kernel code and the arch code now ties into the ptrace implementation.

These patches mostly don't cause any functional change.  They just move
the details of ptrace logic out of core code into tracehook.h inlines,
where they are mostly compiled away to the same as before.  All that
changes is that everything is thoroughly documented and any future
reworking of ptrace, or addition of something new, would not have to touch
core code all over, just change the tracehook.h inlines.

The new linux/ptrace.h inlines are used by the following patches in the
new tracehook_*() inlines.  Using these helpers for the ptrace event stops
makes it simple to change or disable the old ptrace implementation of
these stops conditionally later.

From 6341c393fcc37d58727865f1ee2f65e632e9d4f0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 343/788] tracehook: exec

This moves all the ptrace hooks related to exec into tracehook.h inlines.

This also lifts the calls for tracing out of the binfmt load_binary hooks
into search_binary_handler() after it calls into the binfmt module.  This
change has no effect, since all the binfmt modules' load_binary functions
did the call at the end on success, and now search_binary_handler() does
it immediately after return if successful.  We consolidate the repeated
code, and binfmt modules no longer need to import ptrace_notify().

Subject: [PATCH 344/788] tracehook: unexport ptrace_notify

The ptrace_notify() function should not be called by any modules.  It was
only ever exported to be called by binfmt exec functions.  But that is no
longer necessary since fs/exec.c deals with that generically now.  There
should be no calls to ptrace_notify() from outside the core kernel.

Subject: [PATCH 346/788] tracehook: clone

This moves all the ptrace initialization and tracing logic for task
creation into tracehook.h and ptrace.h inlines.  It reorganizes the code
slightly, but should not change any behavior.

There are four tracehook entry points, at each important stage of task
creation.  This keeps the interface from the core fork.c code fairly
clean, while supporting the complex setup required for ptrace or something
like it.

Subject: [PATCH 348/788] tracehook: release_task

This moves the ptrace-related logic from release_task into tracehook.h and
ptrace.h inlines.  It provides clean hooks both before and after locking
tasklist_lock, for future tracing logic to do more cleanup without the
lock.

This also changes release_task() itself in the rare "zap_leader" case to
set the leader to EXIT_DEAD before iterating.  This maintains the
invariant that release_task() only ever handles a task in EXIT_DEAD.  This
is a common-sense invariant that is already always true except in this one
arcane case of zombie leader whose parent ignores SIGCHLD.

This change is harmless and only costs one store in this one rare case.
It keeps the expected state more consisently sane, which is nicer when
debugging weirdness in release_task().  It also lets some future code in
the tracehook entry points rely on this invariant for bookkeeping.

Subject: [PATCH 351/788] tracehook: tracehook_signal_handler

This defines tracehook_signal_handler() as a hook for the arch signal
handling code to call.  It gives ptrace the opportunity to stop for a
pseudo-single-step trap immediately after signal handler setup is done.

Subject: [PATCH 355/788] tracehook: get_signal_to_deliver

This defines the tracehook_get_signal() hook to allow tracing code to slip
in before normal signal dequeuing.  This lays the groundwork for new
tracing features that can inject synthetic signals outside the normal
queue or control the disposition of delivered signals.  The calling
convention lets tracehook_get_signal() decide both exactly what will
happen and what signal number to report in the handler/exit.

Subject: [PATCH 357/788] tracehook: death

This moves the ptrace logic in task death (exit_notify) into tracehook.h
inlines.  Some code is rearranged slightly to make things nicer.  There is
no change, only cleanup.

There is one hook called with the tasklist_lock write-locked, as ptrace
needs.  There is also a new hook called after exit_state changes and
without locks.  This is a better place for tracing work to be in the
future, since it doesn't delay the whole system with locking.

Subject: [PATCH 358/788] tracehook: force signal_pending()

This defines a new hook tracehook_force_sigpending() that lets tracing
code decide to force TIF_SIGPENDING on in recalc_sigpending().

This is not used yet, so it compiles away to nothing for now.  It lays the
groundwork for new tracing code that can interrupt a task synthetically
without actually sending a signal.

Subject: [PATCH 359/788] tracehook: TIF_NOTIFY_RESUME

This adds tracehook.h inlines to enable a new arch feature in support of
user debugging/tracing.  This is not used yet, but it lays the groundwork
for a debugger to be able to wrangle a task that's possibly running,
without interrupting its syscalls in progress.

Each arch should define TIF_NOTIFY_RESUME, and in their entry.S code treat
it much like TIF_SIGPENDING.  That is, it causes you to take the slow path
when returning to user mode, where you get the full user-mode state
accessible as for signal handling or ptrace.  The arch code should check
TIF_NOTIFY_RESUME after handling TIF_SIGPENDING.  When it's set, clear it
and then call tracehook_notify_resume().

In future, tracing code will call set_notify_resume() when it wants to get
a callback in tracehook_notify_resume().

Subject: [PATCH 360/788] tracehook: asm/syscall.h

This adds asm-generic/syscall.h, which documents what a real
asm-ARCH/syscall.h file should define.  This is not used yet, but will
provide all the machine-dependent details of examining a user system call
about to begin, in progress, or just ended.

Each arch should add an asm-ARCH/syscall.h that defines all the entry
points documented in asm-generic/syscall.h, as short inlines if possible.
This lets us write new tracing code that understands user system call
registers, without any new arch-specific work.

Subject: [PATCH 361/788] tracehook: CONFIG_HAVE_ARCH_TRACEHOOK

This adds the generic HAVE_ARCH_TRACEHOOK kconfig item.  Each arch should
add to some Kconfig file:

	select HAVE_ARCH_TRACEHOOK

if the arch code uses all the latest hooks to enable newfangled tracing
and debugging code.  The comment in arch/Kconfig lists all the
prerequisite arch support.  When all these are available, setting
HAVE_ARCH_TRACEHOOK will allow enabling any new features that depend on
the modern arch interfaces.

Subject: [PATCH 362/788] tracehook: wait_task_inactive

This extends wait_task_inactive() with a new argument so it can be used in
a "soft" mode where it will check for the task changing state unexpectedly
and back off.  There is no change to existing callers.  This lays the
groundwork to allow robust, noninvasive tracing that can try to sample a
blocked thread but back off safely if it wakes up.

Subject: [PATCH 363/788] task_current_syscall

This adds the new function task_current_syscall() on machines where the
asm/syscall.h interface is supported (CONFIG_HAVE_ARCH_TRACEHOOK).  It's
exported for modules to use in the future.  This function safely samples
the state of a blocked thread to collect what system call it is blocked
in, and the six system call argument registers.

Subject: [PATCH 364/788] /proc/PID/syscall

This adds /proc/PID/syscall and /proc/PID/task/TID/syscall magic files.
These use task_current_syscall() to show the task's current system call
number and argument registers, stack pointer and PC.  For a task blocked
but not in a syscall, the file shows "-1" in place of the syscall number,
followed by only the SP and PC.  For a task that's not blocked, it shows
"running".

Subject: [PATCH 365/788] mm: print swapcache page count in
 show_swap_cache_info()

Every arch implements its own show_mem() function.  Most of them share
quite some code, some of them are completely identical.

This series implements a generic version of this function and migrates
almost all architectures to it.

This patch:

Most show_mem() implementations calculate the amount of pages within
the swapcache every time.  Move the output to a more appropriate place
and use the anyway available total_swapcache_pages variable.

Subject: [PATCH 367/788] alpha: use generic show_mem()

Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

	- free pages, printed by show_free_areas()
	- free swap pages, printed by show_swap_cache_info()
	- pages in swapcache, printed by show_swap_cache_info()

where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().

Subject: [PATCH 383/788] frv: use generic show_mem()

Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

	- free pages, printed by show_free_areas()

where show_mem() calls show_free_areas().

Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

	- free pages, printed by show_free_areas()
	- pages in swapcache, printed by show_swap_cache_info()

where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().

Commit 2c96d8d0c17978bbf5eb82314d488f46d4a51280 pushed the
acquisition of hardware_lock to too fine a level, which in turn
will cause problems with cond_resched()s added with
40a2e34a94c336b716f631b2952d233e1ba76e3c.

Subject: [PATCH 400/788] [SCSI] qla2xxx: Set an rport's dev_loss_tmo value in
 a consistent manner.

As there's no point in adding a fixed-fudge value (originally 5
seconds), honor the user settings only.  We also remove the
driver's dead-callback get_rport_dev_loss_tmo function
(qla2x00_get_rport_loss_tmo()).

Subject: [PATCH 404/788] [SCSI] qla2xxx: Allow the user the option of
 disabling iIDMA.

iIDMA support requires the driver issue several additional
fabric-managegment (FM) commands per port discovered during SNS
scanning -- GFPN (Get Fabric Port Name) and GPSC (Get Port Speed
Capabilities).  It has been found during testing that some
switches do not respond as *well* as expected to these commands
(silence -- no ACC nor BS_RJT).  So, to handle such conditions,
allow the user the ability to indirectly disable the FM commands
by disabling iIDMA with the ql2xiidmaenable module-parameter.

Subject: [PATCH 405/788] [SCSI] qla2xxx: Retrieve board serial-number and
 description from VPD.

Recent ISPs have this information written at manufacturing time,
so use the information.  This also reduces future churn of the
qla_devtbl.h file contents, as the driver can now depend on the
information to be present in VPD.

Subject: [PATCH 406/788] [SCSI] qla2xxx: Swap enablement order of EFT and FCE.

The firmware group has suggested that FCE (Fibre Channel Event)
tracing be enabled prior to EFT (Extended Firmware Tracing) to
maximize the capturing of data on the wire.  This change has no
real semantic effect on driver operation, as it's mostly a
shuffling of code.

All fcport->state management should be done within
qla2x00_mark_device_lost(), the assignment of state within
qla2x00_mark_vp_devices_dead() caused associated rports to not be

Subject: [PATCH 410/788] [SCSI] qla2xxx: Correct rport/fcport visibility-state
 handling during loop-resync.

There were several issues here, one, during RSCN handling if a
follow-on RSCN occurred (within interrupt context) the DPC thread
could inadvertantly leave the fcport in a stale lost state.
Secondly, scheduled rport removal is handled exclusively by the
'parent' DPC thread, so wake up the proper thread.  Finally,
process vport loop-resync's only when the vport has in an
"active" state (ID acquired).

Mike Christie noticed a bogus memset. It can be removed as dead code
since the number of bytes in the driver buffer in fixed block mode is
always a multiple of the tape block size.

Subject: [PATCH 418/788] [SCSI] fix shared tag map setup

Currently qla4xxx and stex pass in their can_queue values into
scsi_activate_tcq because they wanted the tag map that large.
The problem with this is that it ends up also setting the queue
depth to that large value. All we want to do this in this case
is set the device queue depth and the other device settings.
We do not need to touch the tag map sizing because the drivers
had setup that map according to their can_queue limits when the
shared map was created.

The scsi mid layer in request_fn will then handle the case where we
have more requests than available tags when it checks the host
queue ready function.

Subject: [PATCH 421/788] [SCSI] fix shared tag map tag allocation

When drivers use a shared tag map we can end up with more requests
than tags, because the tag map is shost->can_queue tags and there
can be sdevs * sdev->queue_depth requests. In scsi_request_fn
if tag allocation fails we just drop down to just dequeueing the
tag without a tag. The problem is that drivers using the shared tag
map rely on a valid tag always being set, because it will use the
tag number to lookup commands later.

This patch has us check if we got a valid tag when the host lock
is held right before we check if the host queue is ready. We do the
check here because to allocate the tag we need the q lock, but
if the tag is bad we want to add the device/q onto the starved list
which requires the host lock.

This allows us also to implement a general notifier chain

From 4c05ae52fcb0e27a2ee4a16d1f31f8c547fd4886 Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Thu, 17 Jul 2008 16:52:57 -0700
Subject: [PATCH 425/788] [SCSI] scsi_dh: Add 'dh_state' sysfs attribute

Implement a 'dh_state' sdev attribute for dynamic device handler
manipulation. A read on the attribute will return the name of
the currently attached device handler or 'detached' if no handler
is attached.
The attribute allows the following strings to be written:
- The name of the device handler to be attached if the state is
  'detached'.
- 'activate' to trigger path activation if a device handler
  is attached.
- 'detach' to detach the currently attached device handler.

From b6ff1b14cdf4b4cb5403f3af2c3272f7e609a241 Mon Sep 17 00:00:00 2001
From: Hannes Reinecke <hare@suse.de>
Date: Thu, 17 Jul 2008 16:53:03 -0700
Subject: [PATCH 426/788] [SCSI] scsi_dh: Update EMC handler

This patch converts the EMC device handler to use a proper
state machine. We now also parse the extended INQUIRY
information to determine if long trespass commands are
supported. And we're now using the long trespass command
correctly. And finally there's now an check at init time
to refuse to attach to devices not supporting EMC-specific
VPD pages.

Subject: [PATCH 427/788] [SCSI] scsi_dh: Update hp_sw hardware handler

This patch updates the hp_sw device handler to properly
check the return codes etc.
And adds the 'correct' machine definitions.

Subject: [PATCH 430/788] [SCSI] scsi_dh: attach to hardware handler from
 dm-mpath

multipath keeps a separate device table which may be
more current than the built-in one.
So we should make sure to always call ->attach whenever
a multipath map with hardware handler is instantiated.
And we should call ->detach on removal, too.

Subject: [PATCH 431/788] [SCSI] scsi_dh: create lookup cache

Create a cache of devices that are seen in a system. This will avoid
the unnecessary traversal of the device list in the scsi_dh when there
are multiple luns of a same type.

Subject: [PATCH 432/788] [SCSI] Host protection capabilities

Controllers that support protection information must indicate this to
the SCSI midlayer so that the ULD can prepare scsi_cmnds accordingly.

This patch implements a host mask and various types of protection:

 - DIF Type 1-3 (between HBA and disk)
 - DIX Type 0-3 (between OS and HBA)

The patch also allows the HBA to set the guard type to something
different than the T10-mandated CRC.

Subject: [PATCH 433/788] [SCSI] Command protection operation

Controllers that support DMA of protection information must be told
explicitly how to handle the I/O.  The controller has no knowledge of
the protection capabilities of the target device so this information
must be passed in the scsi_cmnd.

 - The protection operation tells the HBA whether to generate, strip or
   verify protection information.

 - The protection type tells the HBA which layout the target is
   formatted with.  This is necessary because the controller must be
   able to correctly interpret the included protection information in
   order to verify it.

 - When a scsi_cmnd is reused for error handling the protection
   operation must be cleared and saved while error handling is in
   progress.

 - prot_op and prot_type are placed in an existing hole in scsi_cmnd
   and don't cause the structure to grow.

Subject: [PATCH 434/788] [SCSI] Support devices with protection information

Implement support for DMA of protection information for devices that
are data integrity capable.

 - Add support for mapping an extra scatter-gather list containing
   the protection information.

 - Allocate protection scsi_data_buffer if host is DIX (integrity DMA)
   capable.

 - Accessor function for checking whether a device has protection
   enabled.

Subject: [PATCH 436/788] [SCSI] sd: Identify DIF protection type and
 application tag ownership

If a disk is formatted with protection information (Inquiry bit
PROTECT=1) it is required to support Read Capacity(16).  Force use of
the 16-bit command in this case and extract the P_TYPE field which
indicates whether the disk is formatted using DIF Type 1, 2 or 3.

The ATO (App Tag Own) bit in the Control Mode Page indicates whether
the storage device or the initiator own the contents of the
DIF application tag.

Subject: [PATCH 437/788] [SCSI] sd: Support for SCSI disk (SBC) Data Integrity
 Field

Support for controllers and disks that implement DIF protection
information:

 - During command preparation the RDPROTECT/WRPROTECT must be set
   correctly if the target has DIF enabled.

 - READ(6) and WRITE(6) are not supported when DIF is on.

 - The controller must be told how to handle the I/O via the
   protection operation field in scsi_cmnd.

 - Refactor the I/O completion code that extracts failed LBA from the
   returned sense data and handle DIF failures correctly.

 - sd_dif.c implements the functions required to prepare and complete
   requests with protection information attached.

Subject: [PATCH 438/788] [SCSI] scsi_eh_prep_cmnd should save scmd->underflow

This patch (as1116) fixes a bug in scsi_eh_prep_cmnd() and
scsi_eh_restore_cmnd().  These routines are supposed to save any
values they change and restore them later, but someone forgot to
save & restore scmd->underflow.

This fixes part of the problem reported in Bugzilla #9638.

This patch frees the luntbl dma area in sym_hcb_free if allocated.
Since the luntbl is part of a larger dma coherent area not freeing the
luntbl kept a 64k dma coherent area previous allocated through
dma_alloc_coherent allocated. This prevented a DLPAR remove IO
operation from completing successfully.

Subject: [PATCH 443/788] [SCSI] ibmvfc: Fix hang on module removal

If certain ELS events are received during module removal, after the kthread
is stopped, the rmmod can hang. This fixes the ibmvfc driver so that ELS
events during rmmod are ignored by stopping all device activity prior to
killing the kthread and also changes reinitialization to not attempt a reinit
if the adapter has been taken offline.

Subject: [PATCH 444/788] [SCSI] ibmvfc: Miscellaneous fixes

Properly setup the size of the async event queue. This fixes a bug where async events
were not getting processed by the driver.

Setup target_id field in the driver's target struct so that target sysfs attributes
work for multiple targets.

I goofed and did not see the macro for checking if a request is tagged.
This patch has us use blk_rq_tagged instead of digging into the req->tag.

Patch was made over scsi-misc.

Subject: [PATCH 448/788] [SCSI] 3w-9xxx: add MSI support and misc fixes

This patch for the 3w-9xxx scsi driver applies on top of the
BKL-pushdown changes in -git9.

This patch does the following:

- Increase max AENs drained to 256.
- Add MSI support and "use_msi" module parameter.
- Fix bug in twa_get_param() on 4GB+.
- Use pci_resource_len() for ioremap().

Subject: [PATCH 449/788] [SCSI] ch: fix ch_remove oops

The following commit causes ch_remove oops:

commit 24b42566c3fcbb5a9011d1446783d0f5844ccd45
Author: Greg Kroah-Hartman <gregkh@suse.de>
Date:   Fri May 16 17:55:12 2008 -0700

    SCSI: fix race in device_create

    There is a race from when a device is created with device_create() and
    then the drvdata is set with a call to dev_set_drvdata() in which a
    sysfs file could be open, yet the drvdata will be NULL, causing all
    sorts of bad things to happen.

    This patch fixes the problem by using the new function,
    device_create_drvdata().  It fixes the problem in all of the scsi
    drivers that need it.

    Cc: Kay Sievers <kay.sievers@vrfy.org>
    Cc: Doug Gilbert <dgilbert@interlog.com>
    Cc: James E.J. Bottomley <James.Bottomley@HansenPartnership.com>
    Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The problem is ch_probe stores ch's private data at a wrong place.

We need to store it at scsi_device->sdev_gendev but the above patch
stores it at device struct that device_create_drvdata returns. So we
hit an oops when ch_remove accesses
scsi_device->sdev_gendev->driver_data, which is NULL.

Actually, there wasn't a race because ch doesn't create sysfs files
with device struct that device_create returns. This patch puts back
dev_set_drvdata() to set ch's private data properly.

Subject: [PATCH 450/788] [SCSI] qla2xxx: Issue proper ISP callbacks during
 stop-firmware.

As the original code would incorrectly call the non-ISP24xx/25xx
callbacks during recovery, a stop-firmware failure could result
in improper bit-banging of the RISC and in some cases manifest in
a NMI-watchdog trigger due to the RISC not coming out of its
reset state.

Subject: [PATCH 456/788] dsp56k: Fix BKL pushdown

commit 236b8756a2b6f90498d45b2c36d43e5372f2d4b8 ("dsp56k: BKL pushdown")
removed the `struct inode *inode' parameter from dsp56k_ioctl(), but
forgot to update the use of `inode' in the first line of the function.

Subject: [PATCH 461/788] imxmmc: remove DEBUG definition

Removed DEBUG #define #undef, because module is automaticaly
compiled with -DDEBUG when CONFIG_MMC_DEBUG is defined.
Currently it just generates compiler warning about redefinition.

Subject: [PATCH 464/788] mmc: Export internal host state through debugfs

When CONFIG_DEBUG_FS is set, create a few files under /sys/kernel/debug
containing information about an mmc host's internal state. Currently,
just a single file is created, "ios", which contains information about
the current operating parameters for the bus (clock speed, bus width,
etc.)

Host drivers can add additional files and directories under the host's
root directory by passing the debugfs_root field in struct mmc_host as
the 'parent' parameter to debugfs_create_*.

Subject: [PATCH 465/788] mmc: Add per-card debugfs support

For each card successfully added to the bus, create a subdirectory under
the host's debugfs root with information about the card.

At the moment, only a single file is added to the card directory for
all cards: "state". It reflects the "state" field in struct mmc_card,
indicating whether the card is present, readonly, etc.

For MMC and SD cards (not SDIO), another file is added: "status".
Reading this file will ask the card about its current status and
return it. This can be useful if the card just refuses to respond to
any commands, which might indicate that the card state is not what the
MMC core thinks it is (due to a missing stop command, for example.)

+mISDN is a new modular ISDN driver, in the long term it should replace
+the old I4L driver architecture for passiv ISDN cards.
+It was designed to allow a broad range of applications and interfaces
+but only have the basic function in kernel, the interface to the user
+space is based on sockets with a own address family AF_ISDN.

From 960366cf8dbb3359afaca30cf7fdbf69a6d6dda7 Mon Sep 17 00:00:00 2001
From: Karsten Keil <kkeil@suse.de>
Date: Sun, 27 Jul 2008 01:56:38 +0200
Subject: [PATCH 470/788] Add mISDN DSP

Enable support for digital audio processing capability.
This module may be used for special applications that require
cross connecting of bchannels, conferencing, dtmf decoding
echo cancelation, tone generation, and Blowfish encryption and
decryption.
It may use hardware features if available.

+ * of course, a packet may have much more than 9 sample, but is may have
+ * not excacly the multiple of 9 samples. if there is a rest, the next
+ * received data will complete the block.
+ *
+ * the block is then converted to 9 uLAW samples without the least sigificant
+ * bit. the result is a 7-bit encoded sample.
+ *
+ * the samples will be reoganised to form 8 bytes of data:
+ * (5(6) means: encoded sample no. 5, bit 6)
+ *
+ * 0(6) 0(5) 0(4) 0(3) 0(2) 0(1) 0(0) 1(6)
+ * 1(5) 1(4) 1(3) 1(2) 1(1) 1(0) 2(6) 2(5)
+ * 2(4) 2(3) 2(2) 2(1) 2(0) 3(6) 3(5) 3(4)
+ * 3(3) 3(2) 3(1) 3(0) 4(6) 4(5) 4(4) 4(3)
+ * 4(2) 4(1) 4(0) 5(6) 5(5) 5(4) 5(3) 5(2)
+ * 5(1) 5(0) 6(6) 6(5) 6(4) 6(3) 6(2) 6(1)
+ * 6(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ * 8(6) 8(5) 8(4) 8(3) 8(2) 8(1) 8(0)
+ *
+ * the missing bit 0 of the last byte is filled with some
+ * random noise, to fill all 8 bytes.
+ *
+ * the 8 bytes will be encrypted using blowfish.
+ *
+ * the result will be converted into 9 bytes. the bit 7 is used for
+ * checksumme (CS) for sync (0, 1) and for the last bit:
+ * (5(6) means: crypted byte 5, bit 6)
+ *
+ * 1    0(7) 0(6) 0(5) 0(4) 0(3) 0(2) 0(1)
+ * 0    0(0) 1(7) 1(6) 1(5) 1(4) 1(3) 1(2)
+ * 0    1(1) 1(0) 2(7) 2(6) 2(5) 2(4) 2(3)
+ * 0    2(2) 2(1) 2(0) 3(7) 3(6) 3(5) 3(4)
+ * 0    3(3) 3(2) 3(1) 3(0) 4(7) 4(6) 4(5)
+ * CS   4(4) 4(3) 4(2) 4(1) 4(0) 5(7) 5(6)
+ * CS   5(5) 5(4) 5(3) 5(2) 5(1) 5(0) 6(7)
+ * CS   6(6) 6(5) 6(4) 6(3) 6(2) 6(1) 6(0)
+ * 7(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ *
+ * the checksum is used to detect transmission errors and frame drops.
+ *
+ * synchronisation of received block is done by shifting the upper bit of each
+ * byte (bit 7) to a shift register. if the rigister has the first five bits
+ * (10000), this is used to find the sync. only if sync has been found, the
+ * current block of 9 received bytes are decrypted. before that the check
+ * sum is calculated. if it is incorrect the block is dropped.
+ * this will avoid loud noise due to corrupt encrypted data.
+ *
+ * if the last block is corrupt, the current decoded block is repeated
+ * until a valid block has been received.

+ * The process of adding and removing parties to/from a conference:
+ *
+ * There is a chain of struct dsp_conf which has one or more members in a chain
+ * of struct dsp_conf_member.
+ *
+ * After a party is added, the conference is checked for hardware capability.
+ * Also if a party is removed, the conference is checked again.
+ *
+ * There are 3 different solutions: -1 = software, 0 = hardware-crossconnect
+ * 1-n = hardware-conference. The n will give the conference number.
+ *
+ * Depending on the change after removal or insertion of a party, hardware
+ * commands are given.
+ *
+ * The current solution is stored within the struct dsp_conf entry.
+ */
+
+/*
+ * HOW THE CMX WORKS:
+ *
+ * There are 3 types of interaction: One member is alone, in this case only
+ * data flow from upper to lower layer is done.
+ * Two members will also exchange their data so they are crossconnected.
+ * Three or more members will be added in a conference and will hear each
+ * other but will not receive their own speech (echo) if not enabled.
+ *
+ * Features of CMX are:
+ *  - Crossconnecting or even conference, if more than two members are together.
+ *  - Force mixing of transmit data with other crossconnect/conference members.
+ *  - Echo generation to benchmark the delay of audio processing.
+ *  - Use hardware to minimize cpu load, disable FIFO load and minimize delay.
+ *  - Dejittering and clock generation.
+ *
+ * There are 2 buffers:
+ *
+ *
+ * RX-Buffer
+ *                 R             W
+ *                 |             |
+ * ----------------+-------------+-------------------
+ *
+ * The rx-buffer is a ring buffer used to store the received data for each
+ * individual member. This is only the case if data needs to be dejittered
+ * or in case of a conference where different clocks require reclocking.
+ * The transmit-clock (R) will read the buffer.
+ * If the clock overruns the write-pointer, we will have a buffer underrun.
+ * If the write pointer always has a certain distance from the transmit-
+ * clock, we will have a delay. The delay will dynamically be increased and
+ * reduced.
+ *
+ *
+ * TX-Buffer
+ *                  R        W
+ *                  |        |
+ * -----------------+--------+-----------------------
+ *
+ * The tx-buffer is a ring buffer to queue the transmit data from user space
+ * until it will be mixed or sent. There are two pointers, R and W. If the write
+ * pointer W would reach or overrun R, the buffer would overrun. In this case
+ * (some) data is dropped so that it will not overrun.
+ * Additionally a dynamic dejittering can be enabled. this allows data from
+ * user space that have jitter and different clock source.
+ *
+ *
+ * Clock:
+ *
+ * A Clock is not required, if the data source has exactly one clock. In this
+ * case the data source is forwarded to the destination.
+ *
+ * A Clock is required, because the data source
+ *  - has multiple clocks.
+ *  - has no usable clock due to jitter or packet loss (VoIP).
+ * In this case the system's clock is used. The clock resolution depends on
+ * the jiffie resolution.
+ *
+ * If a member joins a conference:
+ *
+ * - If a member joins, its rx_buff is set to silence and change read pointer
+ *   to transmit clock.
+ *
+ * The procedure of received data from card is explained in cmx_receive.
+ * The procedure of received data from user space is explained in cmx_transmit.
+ * The procedure of transmit data to card is cmx_send.
+ *
+ *
+ * Interaction with other features:
+ *
+ * DTMF:
+ * DTMF decoding is done before the data is crossconnected.
+ *
+ * Volume change:
+ * Changing rx-volume is done before the data is crossconnected. The tx-volume
+ * must be changed whenever data is transmitted to the card by the cmx.
+ *
+ * Tones:
+ * If a tone is enabled, it will be processed whenever data is transmitted to
+ * the card. It will replace the tx-data from the user space.
+ * If tones are generated by hardware, this conference member is removed for
+ * this time.
+ *
+ * Disable rx-data:
+ * If cmx is realized in hardware, rx data will be disabled if requested by
+ * the upper layer. If dtmf decoding is done by software and enabled, rx data
+ * will not be diabled but blocked to the upper layer.
+ *
+ * HFC conference engine:
+ * If it is possible to realize all features using hardware, hardware will be
+ * used if not forbidden by control command. Disabling rx-data provides
+ * absolutely traffic free audio processing. (except for the quick 1-frame
+ * upload of a tone loop, only once for a new tone)

+/* STRUCTURE:
+ *
+ * The dsp module provides layer 2 for b-channels (64kbit). It provides
+ * transparent audio forwarding with special digital signal processing:
+ *
+ * - (1) generation of tones
+ * - (2) detection of dtmf tones
+ * - (3) crossconnecting and conferences (clocking)
+ * - (4) echo generation for delay test
+ * - (5) volume control
+ * - (6) disable receive data
+ * - (7) pipeline
+ * - (8) encryption/decryption
+ *
+ * Look:

+ *         ------card  layer------
+ *             TX            RX
+ *
+ * Above you can see the logical data flow. If software is used to do the
+ * process, it is actually the real data flow. If hardware is used, data
+ * may not flow, but hardware commands to the card, to provide the data flow
+ * as shown.
+ *
+ * NOTE: The channel must be activated in order to make dsp work, even if
+ * no data flow to the upper layer is intended. Activation can be done
+ * after and before controlling the setting using PH_CONTROL requests.
+ *
+ * DTMF: Will be detected by hardware if possible. It is done before CMX
+ * processing.
+ *
+ * Tones: Will be generated via software if endless looped audio fifos are
+ * not supported by hardware. Tones will override all data from CMX.
+ * It is not required to join a conference to use tones at any time.
+ *
+ * CMX: Is transparent when not used. When it is used, it will do
+ * crossconnections and conferences via software if not possible through
+ * hardware. If hardware capability is available, hardware is used.
+ *
+ * Echo: Is generated by CMX and is used to check performane of hard and
+ * software CMX.
+ *
+ * The CMX has special functions for conferences with one, two and more
+ * members. It will allow different types of data flow. Receive and transmit
+ * data to/form upper layer may be swithed on/off individually without loosing
+ * features of CMX, Tones and DTMF.
+ *
+ * Echo Cancellation: Sometimes we like to cancel echo from the interface.
+ * Note that a VoIP call may not have echo caused by the IP phone. The echo
+ * is generated by the telephone line connected to it. Because the delay
+ * is high, it becomes an echo. RESULT: Echo Cachelation is required if
+ * both echo AND delay is applied to an interface.
+ * Remember that software CMX always generates a more or less delay.
+ *
+ * If all used features can be realized in hardware, and if transmit and/or
+ * receive data ist disabled, the card may not send/receive any data at all.
+ * Not receiving is usefull if only announcements are played. Not sending is
+ * usefull if an answering machine records audio. Not sending and receiving is
+ * usefull during most states of the call. If supported by hardware, tones
+ * will be played without cpu load. Small PBXs and NT-Mode applications will
+ * not need expensive hardware when processing calls.
+ *
+ *
+ * LOCKING:
+ *
+ * When data is received from upper or lower layer (card), the complete dsp
+ * module is locked by a global lock.  This lock MUST lock irq, because it
+ * must lock timer events by DSP poll timer.
+ * When data is ready to be transmitted down, the data is queued and sent
+ * outside lock and timer event.
+ * PH_CONTROL must not change any settings, join or split conference members
+ * during process of data.
+ *
+ * HDLC:
+ *
+ * It works quite the same as transparent, except that HDLC data is forwarded
+ * to all other conference members if no hardware bridging is possible.
+ * Send data will be writte to sendq. Sendq will be sent if confirm is received.
+ * Conference cannot join, if one member is not hdlc.

+ * module parameters:
+ * type:
+ *	By default (0), the card is automatically detected.
+ *	Or use the following combinations:
+ *	Bit 0-7   = 0x00001 = HFC-E1 (1 port)
+ * or	Bit 0-7   = 0x00004 = HFC-4S (4 ports)
+ * or	Bit 0-7   = 0x00008 = HFC-8S (8 ports)
+ *	Bit 8     = 0x00100 = uLaw (instead of aLaw)
+ *	Bit 9     = 0x00200 = Disable DTMF detect on all B-channels via hardware
+ *	Bit 10    = spare
+ *	Bit 11    = 0x00800 = Force PCM bus into slave mode. (otherwhise auto)
+ * or   Bit 12    = 0x01000 = Force PCM bus into master mode. (otherwhise auto)
+ *	Bit 13	  = spare
+ *	Bit 14    = 0x04000 = Use external ram (128K)
+ *	Bit 15    = 0x08000 = Use external ram (512K)
+ *	Bit 16    = 0x10000 = Use 64 timeslots instead of 32
+ * or	Bit 17    = 0x20000 = Use 128 timeslots instead of anything else
+ *	Bit 18    = spare
+ *	Bit 19    = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog)
+ * (all other bits are reserved and shall be 0)
+ *	example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM
+ *		 bus (PCM master)
+ *
+ * port: (optional or required for all ports on all installed cards)
+ *	HFC-4S/HFC-8S only bits:
+ *	Bit 0	  = 0x001 = Use master clock for this S/T interface
+ *			    (ony once per chip).
+ *	Bit 1     = 0x002 = transmitter line setup (non capacitive mode)
+ *			    Don't use this unless you know what you are doing!
+ *	Bit 2     = 0x004 = Disable E-channel. (No E-channel processing)
+ *	example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock
+ *		 received from port 1
+ *
+ *	HFC-E1 only bits:
+ *	Bit 0     = 0x0001 = interface: 0=copper, 1=optical
+ *	Bit 1     = 0x0002 = reserved (later for 32 B-channels transparent mode)
+ *	Bit 2     = 0x0004 = Report LOS
+ *	Bit 3     = 0x0008 = Report AIS
+ *	Bit 4     = 0x0010 = Report SLIP
+ *	Bit 5     = 0x0020 = Report RDI
+ *	Bit 8     = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame
+ *			     mode instead.
+ *	Bit 9	  = 0x0200 = Force get clock from interface, even in NT mode.
+ * or	Bit 10	  = 0x0400 = Force put clock to interface, even in TE mode.
+ *	Bit 11    = 0x0800 = Use direct RX clock for PCM sync rather than PLL.
+ *			     (E1 only)
+ *	Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
+ *			     for default.
+ * (all other bits are reserved and shall be 0)
+ *
+ * debug:
+ *	NOTE: only one debug value must be given for all cards
+ *	enable debugging (see hfc_multi.h for debug options)
+ *
+ * poll:
+ *	NOTE: only one poll value must be given for all cards
+ *	Give the number of samples for each fifo process.
+ *	By default 128 is used. Decrease to reduce delay, increase to
+ *	reduce cpu load. If unsure, don't mess with it!
+ *	Valid is 8, 16, 32, 64, 128, 256.
+ *
+ * pcm:
+ *	NOTE: only one pcm value must be given for every card.
+ *	The PCM bus id tells the mISDNdsp module about the connected PCM bus.
+ *	By default (0), the PCM bus id is 100 for the card that is PCM master.
+ *	If multiple cards are PCM master (because they are not interconnected),
+ *	each card with PCM master will have increasing PCM id.
+ *	All PCM busses with the same ID are expected to be connected and have
+ *	common time slots slots.
+ *	Only one chip of the PCM bus must be master, the others slave.
+ *	-1 means no support of PCM bus not even.
+ *	Omit this value, if all cards are interconnected or none is connected.
+ *	If unsure, don't give this parameter.
+ *
+ * dslot:
+ *	NOTE: only one poll value must be given for every card.
+ *	Also this value must be given for non-E1 cards. If omitted, the E1
+ *	card has D-channel on time slot 16, which is default.
+ *	If 1..15 or 17..31, an alternate time slot is used for D-channel.
+ *	In this case, the application must be able to handle this.
+ *	If -1 is given, the D-channel is disabled and all 31 slots can be used
+ *	for B-channel. (only for specific applications)
+ *	If you don't know how to use it, you don't need it!
+ *
+ * iomode:
+ *	NOTE: only one mode value must be given for every card.
+ *	-> See hfc_multi.h for HFC_IO_MODE_* values
+ *	By default, the IO mode is pci memory IO (MEMIO).
+ *	Some cards requre specific IO mode, so it cannot be changed.
+ *	It may be usefull to set IO mode to register io (REGIO) to solve
+ *	PCI bridge problems.
+ *	If unsure, don't give this parameter.
+ *
+ * clockdelay_nt:
+ *	NOTE: only one clockdelay_nt value must be given once for all cards.
+ *	Give the value of the clock control register (A_ST_CLK_DLY)
+ *	of the S/T interfaces in NT mode.
+ *	This register is needed for the TBR3 certification, so don't change it.
+ *
+ * clockdelay_te:
+ *	NOTE: only one clockdelay_te value must be given once
+ *	Give the value of the clock control register (A_ST_CLK_DLY)
+ *	of the S/T interfaces in TE mode.
+ *	This register is needed for the TBR3 certification, so don't change it.

+
+How the codec works:
+--------------------
+
+The volume is increased to increase the dynamic range of the audio signal.
+Each sample is converted to a-LAW with only 16 steps of level resolution.
+A pair of two samples are stored in one byte.
+
+The first byte is stored in the upper bits, the second byte is stored in the
+lower bits.
+
+To speed up compression and decompression, two lookup tables are formed:
+
+- 16 bits index for two samples (law encoded) with 8 bit compressed result.
+- 8 bits index for one compressed data with 16 bits decompressed result.
+
+NOTE: The bytes are handled as they are law-encoded.

+/* module parameters:
+ * type:
+	Value 1	= BRI
+	Value 2	= PRI
+	Value 3 = BRI (multi channel frame, not supported yet)
+	Value 4 = PRI (multi channel frame, not supported yet)
+	A multi channel frame reduces overhead to a single frame for all
+	b-channels, but increases delay.
+	(NOTE: Multi channel frames are not implemented yet.)
+
+ * codec:
+	Value 0 = transparent (default)
+	Value 1 = transfer ALAW
+	Value 2 = transfer ULAW
+	Value 3 = transfer generic 4 bit compression.
+
+ * ulaw:
+	0 = we use a-Law (default)
+	1 = we use u-Law
+
+ * limit:
+	limitation of B-channels to control bandwidth (1...126)
+	BRI: 1 or 2
+	PRI: 1-30, 31-126 (126, because dchannel ist not counted here)
+	Also limited ressources are used for stack, resulting in less channels.
+	It is possible to have more channels than 30 in PRI mode, this must
+	be supported by the application.
+
+ * ip:
+	byte representation of remote ip address (127.0.0.1 -> 127,0,0,1)
+	If not given or four 0, no remote address is set.
+	For multiple interfaces, concat ip addresses. (127,0,0,1,127,0,0,1)
+
+ * port:
+	port number (local interface)
+	If not given or 0, port 931 is used for fist instance, 932 for next...
+	For multiple interfaces, different ports must be given.
+
+ * remoteport:
+	port number (remote interface)
+	If not given or 0, remote port equals local port
+	For multiple interfaces on equal sites, different ports must be given.
+
+ * ondemand:
+	0 = fixed (always transmit packets, even when remote side timed out)
+	1 = on demand (only transmit packets, when remote side is detected)
+	the default is 0
+	NOTE: ID must also be set for on demand.
+
+ * id:
+	optional value to identify frames. This value must be equal on both
+	peers and should be random. If omitted or 0, no ID is transmitted.
+
+ * debug:
+	NOTE: only one debug value must be given for all cards
+	enable debugging (see l1oip.h for debug options)
+
+
+Special mISDN controls:
+
+ op = MISDN_CTRL_SETPEER*
+ p1 = bytes 0-3 : remote IP address in network order (left element first)
+ p2 = bytes 1-2 : remote port in network order (high byte first)
+ optional:
+ p2 = bytes 3-4 : local port in network order (high byte first)
+
+ op = MISDN_CTRL_UNSETPEER*
+

+
+* Only included in some cases.
+
+- Ver = Version
+If version is missmatch, the frame must be ignored.
+
+- T = Type of interface
+Must be 0 for S0 or 1 for E1.
+
+- I = Id present
+If bit is set, four ID bytes are included in frame.
+
+- ID = Connection ID
+Additional ID to prevent Denial of Service attacs. Also it prevents hijacking
+connections with dynamic IP. The ID should be random and must not be 0.
+
+- Coding = Type of codec
+Must be 0 for no transcoding. Also for D-channel and other HDLC frames.
+ 1 and 2 are reserved for explicitly use of a-LAW or u-LAW codec.
+ 3 is used for generic table compressor.
+
+- M = More channels to come. If this flag is 1, the following byte contains
+the length of the channel data. After the data block, the next channel will
+be defined. The flag for the last channel block (or if only one channel is
+transmitted), must be 0 and no length is given.
+
+- Channel = Channel number
+0 reserved
+1-3 channel data for S0 (3 is D-channel)
+1-31 channel data for E1 (16 is D-channel)
+32-127 channel data for extended E1 (16 is D-channel)
+
+- The length is used if the M-flag is 1. It is used to find the next channel
+inside frame.
+NOTE: A value of 0 equals 256 bytes of data.
+ -> For larger data blocks, a single frame must be used.
+ -> For larger streams, a single frame or multiple blocks with same channel ID
+   must be used.
+
+- Time Base = Timestamp of first sample in frame
+The "Time Base" is used to rearange packets and to detect packet loss.
+The 16 bits are sent in network order (MSB first) and count 1/8000 th of a
+second. This causes a wrap arround each 8,192 seconds. There is no requirement
+for the initial "Time Base", but 0 should be used for the first packet.
+In case of HDLC data, this timestamp counts the packet or byte number.
+
+
+Two Timers:
+
+After initialisation, a timer of 15 seconds is started. Whenever a packet is
+transmitted, the timer is reset to 15 seconds again. If the timer expires, an
+empty packet is transmitted. This keep the connection alive.
+
+When a valid packet is received, a timer 65 seconds is started. The interface
+become ACTIVE. If the timer expires, the interface becomes INACTIVE.
+
+
+Dynamic IP handling:
+
+To allow dynamic IP, the ID must be non 0. In this case, any packet with the
+correct port number and ID will be accepted. If the remote side changes its IP
+the new IP is used for all transmitted packets until it changes again.
+
+
+On Demand:
+
+If the ondemand parameter is given, the remote IP is set to 0 on timeout.
+This will stop keepalive traffic to remote. If the remote is online again,
+traffic will continue to the remote address. This is usefull for road warriors.
+This feature only works with ID set, otherwhise it is highly unsecure.
+
+
+Socket and Thread
+-----------------
+
+The complete socket opening and closing is done by a thread.
+When the thread opened a socket, the hc->socket descriptor is set. Whenever a
+packet shall be sent to the socket, the hc->socket must be checked wheter not
+NULL. To prevent change in socket descriptor, the hc->socket_lock must be used.
+To change the socket, a recall of l1oip_socket_open() will safely kill the
+socket process and create a new one.

Subject: [PATCH 478/788] netfilter: fix double-free and use-after free

As suggested by Patrick McHardy, introduce a __krealloc() that doesn't
free the original buffer to fix a double-free and use-after-free bug
introduced by me in netfilter that uses RCU.

Running recent kernels, and using a particular vpn gateway, I've been
having to edit my mails down to get them accepted by the smtp server.

Git bisect led to commit e84f84f276473dcc673f360e8ff3203148bdf0e2 -
netns: place rt_genid into struct net.  The conversion from a != test
to rt_is_expired() put one negative too many: and now my mail works.

Subject: [PATCH 481/788] [patch] vfs: fix lookup on deleted directory

Lookup can install a child dentry for a deleted directory.  This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.

This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode.  But for UBIFS this causes problems because its orphan area can
overflow.

Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.

Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.

New object: set of sysctls [currently - root and per-net-ns].
Contains: pointer to parent set, list of tables and "should I see this set?"
method (->is_seen(set)).
Current lists of tables are subsumed by that; net-ns contains such a beast.
->lookup() for ctl_table_root returns pointer to ctl_table_set instead of
that to ->list of that ctl_table_set.

[folded compile fixes by rdd for configs without sysctl]

Subject: [PATCH 485/788] [PATCH] allow delayed freeing of ctl_table_header

Refcount the sucker; instead of freeing it by the end of unregistration
just drop the refcount and free only when it hits zero.  Make sure that
we _always_ make ->unregistering non-NULL in start_unregistering().

That allows anybody to get a reference to such puppy, preventing its
freeing and reuse.  It does *not* block unregistration.  Anybody who
holds such a reference can
	* try to grab a "use" reference (ctl_head_grab()); that will
succeeds if and only if it hadn't entered unregistration yet.  If it
succeeds, we can use it in all normal ways until we release the "use"
reference (with ctl_head_finish()).  Note that this relies on having
->unregistering become non-NULL in all cases when one starts to unregister
the sucker.
	* keep pointers to ctl_table entries; they *can* be freed if
the entire thing is unregistered.  However, if ctl_head_grab() succeeds,
we know that unregistration had not happened (and will not happen until
ctl_head_finish()) and such pointers can be used safely.

IOW, now we can have inodes under /proc/sys keep references to ctl_table
entries, protecting them with references to ctl_table_header and
grabbing the latter for the duration of operations that require access
to ctl_table.  That won't cause deadlocks, since unregistration will not
be stopped by mere keeping a reference to ctl_table_header.

Subject: [PATCH 486/788] [PATCH] sysctl: make sure that /proc/sys/net/ipv4
 appears before per-ns ones

Massage ipv4 initialization - make sure that net.ipv4 appears as
non-per-net-namespace before it shows up in per-net-namespace sysctls.
That's the only change outside of sysctl.c needed to get sane ordering
rules and data structures for sysctls (esp. for procfs side of that
mess).

Subject: [PATCH 487/788] [PATCH] sysctl: keep track of tree relationships

In a sense, that's the heart of the series.  It's based on the following
property of the trees we are actually asked to add: they can be split into
stem that is already covered by registered trees and crown that is entirely
new.  IOW, if a/b and a/c/d are introduced by our tree, then a/c is also
introduced by it.

That allows to associate tree and table entry with each node in the union;
while directory nodes might be covered by many trees, only one will cover
the node by its crown.  And that will allow much saner logics for /proc/sys
in the next patches.  This patch introduces the data structures needed to
keep track of that.

When adding a sysctl table, we find a "parent" one.  Which is to say,
find the deepest node on its stem that already is present in one of the
tables from our table set or its ancestor sets.  That table will be our
parent and that node in it - attachment point.  Add our table to list
anchored in parent, have it refer the parent and contents of attachment
point.  Also remember where its crown lives.

Subject: [PATCH 489/788] [patch 05/14] hpfs: dont call permission()

hpfs_unlink() calls permission() prior to truncating the file.  HPFS
doesn't define a .permission method, so replace with explicit call to
generic_permission().

This is equivalent, except that devcgroup_inode_permission() and
security_inode_permission() are not called.

The truncation is just an implementation detail of the unlink, so
these security checks are unnecessary.

I suspect that even calling generic_permission() is unnecessary, since
we shouldn't mind if the file isn't writable.  But I leave that to the
maintainer to decide.

* sanitize ecryptfs_permission()
* fix remaining places where ->permission() instances might barf on new
  MAY_... found in mask.

The obvious next target in that direction is permission(9)

folded fix for nfs_permission() breakage from Miklos Szeredi <mszeredi@suse.cz>

Subject: [PATCH 492/788] [patch 3/5] vfs: change remove_suid() to
 file_remove_suid()

All calls to remove_suid() are made with a file pointer, because
(similarly to file_update_time) it is called when the file is written.

Clean up callers by passing in a file instead of a dentry.

Subject: [PATCH 495/788] [PATCH] permission checks for chdir need special
 treatment only on the last step

... so we ought to pass MAY_CHDIR to vfs_permission() instead of having
it triggered on every step of preceding pathname resolution.  LOOKUP_CHDIR
is killed by that.

Subject: [PATCH 497/788] [PATCH] fix MAY_CHDIR/MAY_ACCESS/LOOKUP_ACCESS mess

* MAY_CHDIR is redundant - it's an equivalent of MAY_ACCESS
* MAY_ACCESS on fuse should affect only the last step of pathname resolution
* fchdir() and chroot() should pass MAY_ACCESS, for the same reason why
  chdir() needs that.
* now that we pass MAY_ACCESS explicitly in all cases, LOOKUP_ACCESS can be
  removed; it has no business being in nameidata.

Subject: [PATCH 501/788] [patch 1/4] vfs: utimes: move owner check into
 inode_change_ok()

Add a new ia_valid flag: ATTR_TIMES_SET, to handle the
UTIMES_OMIT/UTIMES_NOW and UTIMES_NOW/UTIMES_OMIT cases.  In these
cases neither ATTR_MTIME_SET nor ATTR_ATIME_SET is in the flags, yet
the POSIX draft specifies that permission checking is performed the
same way as if one or both of the times was explicitly set to a
timestamp.

See the path "vfs: utimensat(): fix error checking for
{UTIME_NOW,UTIME_OMIT} case" by Michael Kerrisk for the patch
introducing this behavior.

This is a cleanup, as well as allowing filesystems (NFS/fuse/...) to
perform their own permission checking instead of the default.

Subject: [PATCH 503/788] [patch 3/4] fat: dont call notify_change

The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change
the file mode before changing the inode attributes.  Replace with
explicit calls to security_inode_setattr(), fat_setattr() and
fsnotify_change().

This is equivalent to the original.  The reason it is needed, is that
later in the series we move the immutable check into notify_change().
That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to
perform the mode change regardless of the immutability of the file.

[Fix error if fat is built as a module.  Thanks to OGAWA Hirofumi for
noticing.]

Subject: [PATCH 504/788] [patch 4/4] vfs: immutable inode checking cleanup

Move the immutable and append-only checks from chmod, chown and utimes
into notify_change().  Checks for immutable and append-only files are
always performed by the VFS and not by the filesystem (see
permission() and may_...() in namei.c), so these belong in
notify_change(), and not in inode_change_ok().

This should be completely equivalent.

Date: Tue, 22 Jul 2008 08:09:30 -0400
Subject: [PATCH 508/788] [PATCH] preparation to __user_walk_fd cleanup

Almost all users __user_walk_fd() and friends care only about struct path.
Get rid of the few that do not.

From 2d8f30380ab8c706f4e0a8f1aaa22b5886e9ac8a Mon Sep 17 00:00:00 2001
From: Al Viro <viro@zeniv.linux.org.uk>
Date: Tue, 22 Jul 2008 09:59:21 -0400
Subject: [PATCH 509/788] [PATCH] sanitize __user_walk_fd() et.al.

* do not pass nameidata; struct path is all the callers want.
* switch to new helpers:
	user_path_at(dfd, pathname, flags, &path)
	user_path(pathname, &path)
	user_lpath(pathname, &path)
	user_path_dir(pathname, &path)  (fail if not a directory)
  The last 3 are trivial macro wrappers for the first one.
* remove nameidata in callers.

Subject: [PATCH 513/788] [PATCH] dup3 fix

Al Viro notice one cornercase that the new dup3() code.  The dup2()
function, as a special case, handles dup-ing to the same file
descriptor.  In this case the current dup3() code does nothing at
all.  I.e., it ingnores the flags parameter.  This shouldn't happen,
the close-on-exec flag should be set if requested.

In case the O_CLOEXEC bit in the flags parameter is not set the
dup3() function should behave in this respect identical to dup2().
This means dup3(fd, fd, 0) should not actively reset the c-o-e
flag.

The patch below implements this minor change.

[AV: credits to Artur Grabowski for bringing that up as potential subtle point
in dup2() behaviour]

Subject: [PATCH 514/788] [PATCH] f_count may wrap around

make it atomic_long_t; while we are at it, get rid of useless checks in affs,
hfs and hpfs - ->open() always has it equal to 1, ->release() - to 0.

Subject: [PATCH 518/788] [PATCH] get rid of corner case in dup3() entirely

Since Ulrich is OK with getting rid of dup3(fd, fd, flags) completely,
to hell the damn thing goes.  Corner case for dup2() is handled in
sys_dup2() (complete with -EBADF if dup2(fd, fd) is called with fd
that is not open), the rest is done in dup3().

Subject: [PATCH 519/788] [PATCH] fix RLIM_NOFILE handling

* dup2() should return -EBADF on exceeded sysctl_nr_open
* dup() should *not* return -EINVAL even if you have rlimit set to 0;
  it should get -EMFILE instead.

Check for orig_start exceeding rlimit taken to sys_fcntl().
Failing expand_files() in dup{2,3}() now gets -EMFILE remapped to -EBADF.
Consequently, remaining checks for rlimit are taken to expand_files().

Subject: [PATCH 531/788] ALSA: Allow to force model to intel-mac-v3 in
 snd_hda_intel (sigmatel).

Currently, even if you pass model=intel-mac-v3 as a module parameter to
snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still
try to auto-detect the model type. This is a problem on my MacBook Pro 1st
generation, which needs intel-mac-v3, but sometimes incorrectly reports
0x00000100 as subsystem id, which causes the switch in patch_stac922x to
select intel-mac-v4.

To fix this, I added a new model called intel-mac-auto, so in case no
module parameter is passed, and an Intel Mac board is detected, the
model will be automatically detected, while no detection will be done
if the model is forced to intel-mac-v3.

This problem has been around for quite a while, and I used to fix it
by moving the case statement for 0x00000100 in patch_stac922x so that
intel-mac-v3 is chosen.

Another way to fix the problem would be to check if a module parameter
was set directly in patch_stac922x, using something like this:
if (spec->board_config == STAC_INTEL_MAC_V3 &&
	!codec->bus->modelname) {

But I think it is less elegant (if you prefer that way, I can prepare a
patch).

Subject: [PATCH 532/788] KVM: SVM: allow enabling/disabling NPT by reloading
 only the architecture module

If NPT is enabled after loading both KVM modules on AMD and it should be
disabled, both KVM modules must be reloaded. If only the architecture module is
reloaded the behavior is undefined. With this patch it is possible to disable
NPT only by reloading the kvm_amd module.

 instead of reading from GDT

There is no guarantee that the old TSS descriptor in the GDT contains
the proper base address. This is the case for Windows installation's
reboot-via-triplefault.

Use guest registers instead. Also translate the address properly.

Subject: [PATCH 535/788] KVM: Avoid instruction emulation when event delivery
 is pending

When an event (such as an interrupt) is injected, and the stack is
shadowed (and therefore write protected), the guest will exit.  The
current code will see that the stack is shadowed and emulate a few
instructions, each time postponing the injection.  Eventually the
injection may succeed, but at that time the guest may be unwilling
to accept the interrupt (for example, the TPR may have changed).

This occurs every once in a while during a Windows 2008 boot.

Fix by unshadowing the fault address if the fault was due to an event
injection.

There is a call to local_irq_restore in the normal exit case, so it would
seem that there should be one on an error return as well.

Subject: [PATCH 541/788] KVM: s390: Fix guest kconfig

Cornelia Huck noticed that a modular virtio without kvm guest support
leads to a build error in the s390 virtio transport:

CONFIG_VIRTIO=m leads to
ERROR: "vmem_add_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "max_pfn" [drivers/s390/kvm/kvm_virtio.ko] undefined!
ERROR: "vmem_remove_mapping" [drivers/s390/kvm/kvm_virtio.ko] undefined!

The virtio transport only works with kvm guest support and only as a
builtin. Lets change the build process of drivers/s390/kvm/kvm_virtio.c
to depend on kvm guest support, which is also a bool.

CONFIG_S390_GUEST already selects CONFIG_VIRTIO, that should prevent
CONFIG_S390_GUEST=y CONFIG_VIRTIO=n situations.

Subject: [PATCH 543/788] KVM: s390: Fix program check on interrupt delivery
 handling

The current interrupt handling on s390 misbehaves on an error case. On s390
each cpu has the prefix area (lowcore) for interrupt delivery. This memory
must always be available. If we fail to access the prefix area for a guest
on interrupt delivery the configuration is completely unusable. There is no
point in sending another program interrupt to an inaccessible lowcore.
Furthermore, we should not bug the host kernel, because this can be triggered
by userspace. I think the guest kernel itself can not trigger the problem, as
SET PREFIX and SIGNAL PROCESSOR SET PREFIX both check that the memory is
available and sane. As this is a userspace bug (e.g. setting the wrong guest
offset, unmapping guest memory) we should kill the userspace process instead
of BUGing the host kernel.
In the long term we probably should notify the userspace process about this
problem.

Subject: [PATCH 545/788] KVM: s390: Fix possible host kernel bug on lctl(g)
 handling

The lctl(g) instructions require a specific alignment for the parameters.
The architecture requires a specification program check if these alignments
are not used. Enforcing this alignment also removes a possible host BUG,
since the get_guest functions check for proper alignment and emits a BUG.

When guest invalidates a large tlb map, there may be more than one
corresponding shadow tlb maps that need to be invalidated. Use eaddr and eend
to find these shadow tlb maps.

Subject: [PATCH 548/788] [ARM] fix VIPT/VIVT macro optimisations, add comments

cacheflush.h was doing:

... VIVT only stuff
... VIPT only stuff
... VIVT or VIPT stuff

which is clearly bogus - we would only ever use the "VIVT or VIPT" case
when both VIVT and VIPT are not selected.  Fix this.

Add comments to each case, including noting the impossibility of
correctly detecting the cache type of ARM926 and ARMv6 cores from
the cache type register in the "VIVT or VIPT" case.

Subject: [PATCH 549/788] [ARM] Fix shared mmap when more than two maps of the
 same file exist

The shared mmap code works fine for the test case, which only checked
for two shared maps of the same file.  However, three shared maps
result in one mapping remaining cached, resulting in stale data being
visible via that mapping.  Fix this.

Subject: [PATCH 551/788] net: missing bits of net-namespace / sysctl

Piss-poor sysctl registration API strikes again, film at 11...
What we really need is _pathname_ required to be present in
already registered table, so that kernel could warn about bad
order.  That's the next target for sysctl stuff (and generally
saner and more explicit order of initialization of ipv[46]
internals wouldn't hurt either).

For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and
make sure that sufficient skeleton is there before we start registering
per-net sysctls.

From: David Brownell <dbrownell@users.sourceforge.net>
Date: Sun, 27 Jul 2008 02:34:45 -0700
Subject: [PATCH 552/788] avr32: some mmc/sd cleanups

Minor cleanups for the MMC/SD support on avr32:

 - Make at32_add_device_mci() properly initialize "missing"
   platform data ... so boards like STK1002 won't try GPIO 0.

 - Switch over to gpio_is_valid() instead of testing for only
   one designated value.

 - Provide STK1002 platform data for the unlikely case that
   switches are set so first Ethernet controller isn't in use.
   (That's the only way to get card detect and writeprotect
   switch sensing on the STK1000.)

And get rid of one "unused variable" warning.

Subject: [PATCH 555/788] V4L/DVB (8505): saa7134-empress.c: fix deadlock

ts_release() locked a mutex that videobuf_stop() also tried to obtain.
But ts_release() shouldn't hold that mutex at all.

Make empress_users atomic as well to prevent possible race condition.

From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sat, 26 Jul 2008 08:26:43 -0300
Subject: [PATCH 567/788] V4L/DVB (8523): v4l2-dev: remove unused type and
 type2 field from video_device

The type and type2 fields were unused and so could be removed.
Instead add a vfl_type field that contains the type of the video
device.

Subject: [PATCH 568/788] V4L/DVB (8524): videodev: copy the VID_TYPE defines
 to videodev.h

The VID_TYPE defines are V4L1 specific, so copy them back to videodev.h.
In videodev2.h ensure that they are not used in the kernel (you need
to include videodev.h instead) and mark them are deprecated.

There is no reason to protect the i2c gate handling within the mxl5007t
state mutex.

Thanks to Steven Toth for pointing this out.

Subject: [PATCH 575/788] V4L/DVB (8532): mxl5007t: remove excessive locks

The use of mutex locking is overly paranoid in this driver.
The only locks we need are around the manipulation of the
register arrays. The other locks are not needed - remove them.

Thanks to Steven Toth for pointing this out.

Subject: [PATCH 576/788] [SCSI] extend the last_sector_bug flag to cover more
 sectors

The last_sector_bug flag was added to work around a bug in certain usb
cardreaders, where they would crash if a multiple sector read included the
last sector. The original implementation avoids this by e.g. splitting an 8
sector read which includes the last sector into a 7 sector read, and a single
sector read for the last sector.  The flag is enabled for all USB devices.

This revealed a second bug in other usb cardreaders, which crash when they
get a multiple sector read which stops 1 sector short of the last sector.
Affected hardware includes the Kingston "MobileLite" external USB cardreader
and the internal USB cardreader on the Asus EeePC.

Extend the last_sector_bug workaround to ensure that any access which touches
the last 8 hardware sectors of the device is a single sector long.  Requests
are shrunk as necessary to meet this constraint.

This gives us a safety margin against potential unknown or future bugs
affecting multi-sector access to the end of the device.  The two known bugs
only affect the last 2 sectors.  However, they suggest that these devices
are prone to fencepost errors and that multi-sector access to the end of the
device is not well tested.  Popular OS's use multi-sector accesses, but they
rarely read the last few sectors.  Linux (with udev & vol_id) automatically
reads sectors from the end of the device on insertion.  It is assumed that
single sector accesses are more thoroughly tested during development.

Subject: [PATCH 579/788] V4L/DVB (8534): remove select's of FW_LOADER

After commit d9b19199e4894089456aaad295023263b5225c1a
(always enable FW_LOADER unless EMBEDDED=y) we can remove
the FW_LOADER select's and corresponding dependencies
on HOTPLUG.

Subject: [PATCH 582/788] missing bits of net-namespace / sysctl

Piss-poor sysctl registration API strikes again, film at 11...

What we really need is _pathname_ required to be present in already
registered table, so that kernel could warn about bad order.  That's the
next target for sysctl stuff (and generally saner and more explicit
order of initialization of ipv[46] internals wouldn't hurt either).

For the time being, here are full fixups required by ..._rotable()
stuff; we make per-net sysctl sets descendents of "ro" one and make sure
that sufficient skeleton is there before we start registering per-net
sysctls.

Subject: [PATCH 589/788] x86: fix cpu hotplug on 32bit

commit 3e9704739daf46a8ba6593d749c67b5f7cd633d2 ("x86: boot secondary
cpus through initial_code") causes the kernel to crash when a CPU is
brought online after the read only sections have been write
protected. The write to initial_code in do_boot_cpu() fails.

Move inital_code to .cpuinit.data section.

Subject: [PATCH 590/788] sparc, sparc64: use arch/sparc/include

The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.

Subject: [PATCH 595/788] V4L/DVB (8544): gspca: probe/open race.

The device is flagged present after it is registered. During that window calls
to open() that should work fail with -ENODEV. Reversing the order fixes
the race.

Subject: [PATCH 596/788] V4L/DVB (8546): saa7146: fix read from uninitialized
 memory

The offset field of the scatterlist entry *after* the last valid scatterlist
entry was used instead of the first scatterlist entry (as was the intention
of this code).

This worked fine until the kzalloc of the sglist was replaced with kmalloc
and sg_init_table only zeroed the exact needed length. Apparently kzalloc
zeroes a bit more than is strictly necessary so the offset field was
always 0 in the past.

But now the offset field was suddenly random and this led to broken captures.

The new super.c:nfs_remount function doesn't check the validity of the
options/options4 pointers. Unfortunately, this seems to happend.
The obvious patch seems to check the pointers, and not to do anything if
the happend to be NULL.

Tested on an XScale PXA255 system, latest git.

Subject: [PATCH 603/788] sparc64: tracehook syscall

This changes sparc64 syscall tracing to use the new tracehook.h entry
points.

[ Add assembly changes to force an immediate -ENOSYS return from
  the system call when syscall_trace() returns non-zero at syscall
  entry.  -DaveM ]

Subject: [PATCH 615/788] stop_machine: add ALL_CPUS option

-allow stop_mahcine_run() to call a function on all cpus. Calling
 stop_machine_run() with a 'ALL_CPUS' invokes this new behavior.
 stop_machine_run() proceeds as normal until the calling cpu has
 invoked 'fn'. Then, we tell all the other cpus to call 'fn'.

Subject: [PATCH 616/788] Simplify stop_machine

stop_machine creates a kthread which creates kernel threads.  We can
create those threads directly and simplify things a little.  Some care
must be taken with CPU hotunplug, which has special needs, but that code
seems more robust than it was in the past.

Subject: [PATCH 617/788] Hotplug CPU: don't check cpu_online after
 take_cpu_down

Akinobu points out that if take_cpu_down() succeeds, the cpu must be offline.
Remove the cpu_online() check, and put a BUG_ON().

Quoting Akinobu Mita:
   Actually the cpu_online() check was necessary before appling this
   stop_machine: simplify patch.

   With old __stop_machine_run(), __stop_machine_run() could succeed
   (return !IS_ERR(p) value) even if take_cpu_down() returned non-zero value.
   The return value of take_cpu_down() was obtained through kthread_stop()..

Subject: [PATCH 618/788] stop_machine(): stop_machine_run() changed to use cpu
 mask

Instead of a "cpu" arg with magic values NR_CPUS (any cpu) and ~0 (all
cpus), pass a cpumask_t.  Allow NULL for the common case (where we
don't care which CPU the function is run on): temporary cpumask_t's
are usually considered bad for stack space.

This deprecates stop_machine_run, to be removed soon when all the
callers are dead.

Subject: [PATCH 625/788] powerpc: kill useless SMT code in prom_hold_cpus

This piece of code is broken for >2 threads, and possibly in some
other subtle ways (such as comparing a value obtained from an
"ibm,ppc-interrupt-server#s" property to a value obtained from a
"reg" property) and doesn't seem to have any useful purpose in the
first place other than a dubious warning in case NR_CPUS is too
small, which probably isn't the right place to do so.

Subject: [PATCH 627/788] powerpc: Update cpu_sibling_maps dynamically

Rather doing one initialization pass over all the per-cpu
cpu_sibling_maps at boot, update the maps at cpu online/offline time.

This is a behavior change -- the thread_siblings attribute now
reflects only online siblings, whereas it would display offline
siblings before.  The new behavior matches that of x86, and is
arguably more useful.

Subject: [PATCH 628/788] powerpc: Call tracehook_signal_handler() when setting
 up signal frames

This makes the powerpc signal handling code call tracehook_signal_handler()
after a handler is set up.  This means that using PTRACE_SINGLESTEP to
enter a signal handler will report to ptrace on the first instruction of
the handler, instead of the second.  This is consistent with what x86 and
other machines do, and what users and debuggers want.

BenH: Fixed up the test for the trap value.

In addition, the assembly changes allow do_syscall_trace_enter() to
abort the syscall without losing the information about the original

Subject: [PATCH 630/788] powerpc: Add asm/syscall.h with the tracehook entry
 points

Add asm/syscall.h for powerpc with all the required entry points.
This will allow arch-independent tracing code for system calls.

BenH: Fixed up use of regs->trap to properly mask low bit

Subject: [PATCH 631/788] powerpc: Add TIF_NOTIFY_RESUME support for tracehook

This adds TIF_NOTIFY_RESUME support for powerpc.  When set,
we call tracehook_notify_resume() on the way to user mode.
This overloads do_signal() to do the work, but changes its
arguments to it has the TIF_* bits handy in a register and
drops the useless first argument that was always zero.

Subject: [PATCH 637/788] powerpc: Make core id information available to
 userspace

Existing Open Firmware practice is to report each processor core as a
separate node in the device tree.  Report the value of the "reg" OF
property corresponding to a logical CPU's device node as the core_id
attribute in /sys/devices/system/cpu/cpu*/topology/core_id.

Subject: [PATCH 638/788] powerpc: Show processor cache information in sysfs

Collect cache information from the OF device tree and display it in
the cpu hierarchy in sysfs.  This is intended to be compatible at the
userspace level with x86's implementation[1], hence some of the funny
attribute names.  The arrangement of cache info is not immediately
intuitive, but (again) it's for compatibility's sake.

The cache attributes exposed are:

type (Data, Instruction, or Unified)
level (1, 2, 3...)
size
coherency_line_size
number_of_sets
ways_of_associativity

All of these can be derived on platforms that follow the OF PowerPC
Processor binding.  The code "publishes" only those attributes for
which it is able to determine values; attributes for values which
cannot be determined are not created at all.

[1] arch/x86/kernel/cpu/intel_cacheinfo.c

BenH: Turned some printk's into pr_debug, added better NULL checking
in a couple of places.

Subject: [PATCH 639/788] powerpc/mm: Implement _PAGE_SPECIAL & pte_special()
 for 64-bit

Implement _PAGE_SPECIAL and pte_special() for 64-bit powerpc. This bit will
be used by the fast get_user_pages() to differenciate PTEs that correspond
to a valid struct page from special mappings that don't such as IO mappings
obtained via io_remap_pfn_ranges().

Subject: [PATCH 640/788] powerpc/powermac: Use sane default baudrate for SCC
 debugging

When using the "sccdbg" option to route early kernel messages and
xmon to the SCC serial port on PowerMacs, when this wasn't the
configured output port of Open Firmware, we initialize the baudrate
to 57600bps. This isn't a very good default on some powermacs where
both the FW and pmac_zilog will default to 38400. This fixes it to
use the same logic as pmac_zilog to pick a default speed.

Subject: [PATCH 642/788] powerpc: Disable 64K hugetlb support when doing 64K
 SPU mappings

The 64K SPU local store mapping feature is incompatible with the
64K huge pages support due to the inability of some parts of
the memory management to differenciate between them while they
use a different page table format.

For now, disable 64K huge pages when CONFIG_SPU_FS_64K_LS,
in the long run, this can be fixed by making this feature use
the hugetlb page table format.

Subject: [PATCH 648/788] binfmt_elf_fdpic: Magical stack pointer index, for
 NEW_AUX_ENT compat.

While implementing binfmt_elf_fdpic on SH it quickly became apparent
that SH was the first platform to support both binfmt_elf_fdpic and
binfmt_elf, as well as the only of the FDPIC platforms to make use of the
auxvt.

Currently binfmt_elf_fdpic uses a special version of NEW_AUX_ENT() where
the first argument is the entry displacement after csp has been adjusted,
being reset after each adjustment. As we have no ability to sort this out
through the platform's ARCH_DLINFO, this index needs to be managed
entirely in create_elf_fdpic_tables(). Presently none of the platforms
that set their own auxvt entries are able to do so through their
respective ARCH_DLINFOs when using binfmt_elf_fdpic.

In addition to this, binfmt_elf_fdpic has been looking at
DLINFO_ARCH_ITEMS for the number of architecture-specific entries in the
auxvt. This is legacy cruft, and is not defined by any platforms in-tree,
even those that make heavy use of the auxvt. AT_VECTOR_SIZE_ARCH is
always available, and contains the number that is of interest here, so we
switch to using that unconditionally as well.

As this has direct bearing on how much stack is used, platforms that have
configurable (or dynamically adjustable) NEW_AUX_ENT calls need to either
make AT_VECTOR_SIZE_ARCH more fine-grained, or leave it as a worst-case
and live with some lost stack space if those entries aren't pushed (some
platforms may also need to purposely sacrifice some space here for
alignment considerations, as noted in the code -- although not an issue
for any FDPIC-capable platform today).

Subject: [PATCH 650/788] sh: Make dump_task dependent on ELF core.

Currently this is only linked in for CONFIG_BINFMT_ELF, make it dependent
on CONFIG_ELF_CORE, so it's both selectable there and also linked in for
CONFIG_BINFMT_ELF_FDPIC.

From 02f7e627f9248a478cf790112a07ae2c612b895a Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Tue, 3 Jun 2008 18:48:54 +0900
Subject: [PATCH 652/788] sh: Consolidate segment modifiers across mmu/nommu
 systems.

This moves get_fs/set_fs() and friends in to asm/segment.h. The
mm_segment_t definition is likewise consolidated from the _32/_64 split.

This is prepatory groundwork for using the generic address space limit
and verification routines across mmu/nommu configs.

Subject: [PATCH 653/788] sh: Support variable page sizes on nommu.

PAGE_SIZE doesn't need to be fixed at 4096 on nommu, so stub in a !MMU
case for the various PAGE_SIZE Kconfig options.

Date: Tue, 3 Jun 2008 18:54:02 +0900
Subject: [PATCH 654/788] sh: Add support for 16kB PAGE_SIZE.

16kB is a useful size on nommu, while 64kB still tends to be too big to
be useful. Newer MMUs are likely to support this as well, so plug it
in in anticipation of those, too.

Subject: [PATCH 659/788] sh: Add SCIF2 support for SH7763.

SH7763 has 3 SCIF device. Current code supports SCIF0 and 1.
SCIF0 and 1 are same register constitution, but only SCIF2 is different.
I added support of SCIF2.

 connect/disconnect

The connect and disconnect functions are unnecessary - everything they do can be
accomplished in the initial probe - so remove them.

  - process_32.c: default_idle()
  - time_32.c: struct clocksource_sh
  - timers/timer-tmu.c: struct tmu_timer_ops
- remove the following unused functions (no CONFIG_BLK_DEV_FD on sh):
  - process_{32,64}.c: disable_hlt()
  - process_{32,64}.c: enable_hlt()

Subject: [PATCH 670/788] sh: Remove sh_pcic_io_xxx function from Solution
 Engine IO code

sh_pcic_io_xxx function are very old.
In linux-2.4, mrshpc_ss socket driver used this function.
But there is not this driver to the present kernel.
I deleted these cords and checked operation.

Subject: [PATCH 674/788] sh: Optimized flush_icache_range() implementation.

Add implementation of flush_icache_range() suitable for signal handler
and kprobes. Remove flush_cache_sigtramp() and change signal.c to use
flush_icache_range().

From f2fb4e4f647dabf1177d3ce164988e73482d76b1 Mon Sep 17 00:00:00 2001
From: Stuart Menefy <stuart.menefy@st.com>
Date: Wed, 2 Jul 2008 17:51:23 +0900
Subject: [PATCH 676/788] sh: Conditionally re-enable IRQs in fault path.

The current kernel behaviour is to reenable interrupts unconditionally
when taking a page fault. This patch changes this to only enable them
if interrupts were previously enabled.

It also fixes a problem seen with this fix in place: the kernel previously
flushed the vsyscall page when handling a signal, which is not only
unncessary, but caused a possible sleep with interrupts disabled.

Subject: [PATCH 693/788] fix sh ptep_get_and_clear breakage

Commit 1ea0704e0da65b2b46f9142ff1391163aac24060
(mm: add a ptep_modify_prot transaction abstraction)
triggered on sh build errors like the following:

<--  snip  -->

...
  CC      arch/sh/mm/pg-sh4.o
cc1: warnings being treated as errors
include2/asm/pgtable.h:139: error: 'ptep_get_and_clear' declared inline after being called
include2/asm/pgtable.h:139: error: previous declaration of 'ptep_get_and_clear' was here
make[2]: *** [arch/sh/mm/pg-sh4.o] Error 1

<--  snip  -->

Since there's no good reason for marking these global functions as
"inline" this patch therefore removes the inline's.

From 1312994c8008d66806d9452c15d50df86a031437 Mon Sep 17 00:00:00 2001

Subject: [PATCH 697/788] sh: Merge sh7343 and sh7722 clock code

This code makes sh7343 share the sh7722 clock code. Instead of just using
the good and very old sh7343 clock implmentation, switch to the new MSTPCR
enabled clock code. SIU clocks are disabled on sh7343 for now.

With this change all SuperH Mobile devices now use the same clock code.

Without this patch, signals sent during architecture specific signal
handling (typically as a result of the user's stack being inaccessible)
are ignored.

This is the SH version of commit c3ff8ec31c1249d268cd11390649768a12bec1b9
which was for the i386.

Date: Mon, 28 Jul 2008 18:36:13 +0900
Subject: [PATCH 708/788] sh: Workaround for __put_user_asm() bug with gcc 4.x
 on big-endian.

I think this problem is GCC(4.1.2) bug.
Syscall "getdents" returned "dirent->d_off" is always 0.
I think other EB enviroment have same problem.

Problem code
0c03c954 <filldir>:
 :
 c03c97a:       58 f7           mov.l   @(28,r15),r8 !-> offset (high)
 c03c97c:       59 f8           mov.l   @(32,r15),r9 !-> offset (low)
 c03c97e:       53 f9           mov.l   @(36,r15),r3
 c03c980:       54 fa           mov.l   @(40,r15),r4
 :
 c03c9a0:       21 82           mov.l   r8,@r1 !offset(high) -> dirent->d_off

It's workaround patch.

Subject: [PATCH 716/788] i2c: S3C2410: Pass the I2C bus number via drivers
 platform data

Allow the platform data to specify the bus bumber that the
new I2C bus will be given. This is to allow the use of the
board registration mechanism to specify the new style of
I2C device registration which allows boards to provide a
list of attached devices.

Note, as discussed on the mailing list, we have dropped
backwards compatibility of adding an dynamic bus number
as it should not affect most boards to have the bus pinned
to 0 if they have either not specified platform data for
driver. Any board supplying platform data will automatically
have the bus_num field set to 0, and anyone who needs the
driver on a different bus number can supply platform data
to set bus_num.

+Upgrading I2C Drivers to the new 2.6 Driver Model
+=================================================
+
+Ben Dooks <ben-linux@fluff.org>
+
+Introduction
+------------
+
+This guide outlines how to alter existing Linux 2.6 client drivers from
+the old to the new new binding methods.
+
+
+Example old-style driver
+------------------------
+
+
+struct example_state {
+	struct i2c_client	client;
+	....
+};
+
+static struct i2c_driver example_driver;
+
+static unsigned short ignore[] = { I2C_CLIENT_END };
+static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+I2C_CLIENT_INSMOD;
+
+static int example_attach(struct i2c_adapter *adap, int addr, int kind)
+{
+	struct example_state *state;
+	struct device *dev = &adap->dev;  /* to use for dev_ reports */
+	int ret;
+
+	state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+	if (state == NULL) {
+		dev_err(dev, "failed to create our state\n");
+		return -ENOMEM;
+	}
+
+	example->client.addr    = addr;
+	example->client.flags   = 0;
+	example->client.adapter = adap;
+
+	i2c_set_clientdata(&state->i2c_client, state);
+	strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+	ret = i2c_attach_client(&state->i2c_client);
+	if (ret < 0) {
+		dev_err(dev, "failed to attach client\n");
+		kfree(state);
+		return ret;
+	}
+
+	dev = &state->i2c_client.dev;
+
+	/* rest of the initialisation goes here. */
+
+	dev_info(dev, "example client created\n");
+
+	return 0;
+}
+
+static int __devexit example_detach(struct i2c_client *client)
+{
+	struct example_state *state = i2c_get_clientdata(client);
+
+	i2c_detach_client(client);
+	kfree(state);
+	return 0;
+}
+
+static int example_attach_adapter(struct i2c_adapter *adap)
+{
+	return i2c_probe(adap, &addr_data, example_attach);
+}
+
+static struct i2c_driver example_driver = {
+ 	.driver		= {
+		.owner		= THIS_MODULE,
+		.name		= "example",
+	},
+	.attach_adapter = example_attach_adapter,
+	.detach_client	= __devexit_p(example_detach),
+	.suspend	= example_suspend,
+	.resume		= example_resume,
+};
+
+
+Updating the client
+-------------------
+
+The new style binding model will check against a list of supported
+devices and their associated address supplied by the code registering
+the busses. This means that the driver .attach_adapter and
+.detach_adapter methods can be removed, along with the addr_data,
+as follows:
+
+- static struct i2c_driver example_driver;
+
+- static unsigned short ignore[] = { I2C_CLIENT_END };
+- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+- I2C_CLIENT_INSMOD;
+
+- static int example_attach_adapter(struct i2c_adapter *adap)
+- {
+- 	return i2c_probe(adap, &addr_data, example_attach);
+- }
+
+ static struct i2c_driver example_driver = {
+-	.attach_adapter = example_attach_adapter,
+-	.detach_client	= __devexit_p(example_detach),
+ }
+
+Add the probe and remove methods to the i2c_driver, as so:
+
+ static struct i2c_driver example_driver = {
++	.probe		= example_probe,
++	.remove		= __devexit_p(example_remove),
+ }
+
+Change the example_attach method to accept the new parameters
+which include the i2c_client that it will be working with:
+
+- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
++ static int example_probe(struct i2c_client *client,
++			   const struct i2c_device_id *id)
+
+Change the name of example_attach to example_probe to align it with the
+i2c_driver entry names. The rest of the probe routine will now need to be
+changed as the i2c_client has already been setup for use.
+
+The necessary client fields have already been setup before
+the probe function is called, so the following client setup
+can be removed:
+
+-	example->client.addr    = addr;
+-	example->client.flags   = 0;
+-	example->client.adapter = adap;
+-
+-	strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+The i2c_set_clientdata is now:
+
+-	i2c_set_clientdata(&state->client, state);
++	i2c_set_clientdata(client, state);
+
+The call to i2c_attach_client is no longer needed, if the probe
+routine exits successfully, then the driver will be automatically
+attached by the core. Change the probe routine as so:
+
+-	ret = i2c_attach_client(&state->i2c_client);
+-	if (ret < 0) {
+-		dev_err(dev, "failed to attach client\n");
+-		kfree(state);
+-		return ret;
+-	}
+
+
+Remove the storage of 'struct i2c_client' from the 'struct example_state'
+as we are provided with the i2c_client in our example_probe. Instead we
+store a pointer to it for when it is needed.
+
+struct example_state {
+-	struct i2c_client	client;
++	struct i2c_client	*client;
+
+the new i2c client as so:
+
+-	struct device *dev = &adap->dev;  /* to use for dev_ reports */
++ 	struct device *dev = &i2c_client->dev;  /* to use for dev_ reports */
+
+And remove the change after our client is attached, as the driver no
+longer needs to register a new client structure with the core:
+
+-	dev = &state->i2c_client.dev;
+
+In the probe routine, ensure that the new state has the client stored
+in it:
+
+static int example_probe(struct i2c_client *i2c_client,
+			 const struct i2c_device_id *id)
+{
+	struct example_state *state;
+ 	struct device *dev = &i2c_client->dev;
+	int ret;
+
+	state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+	if (state == NULL) {
+		dev_err(dev, "failed to create our state\n");
+		return -ENOMEM;
+	}
+
++	state->client = i2c_client;
+
+Update the detach method, by changing the name to _remove and
+to delete the i2c_detach_client call. It is possible that you
+can also remove the ret variable as it is not not needed for
+any of the core functions.
+
+- static int __devexit example_detach(struct i2c_client *client)
++ static int __devexit example_remove(struct i2c_client *client)
+{
+	struct example_state *state = i2c_get_clientdata(client);
+
+-	i2c_detach_client(client);
+
+And finally ensure that we have the correct ID table for the i2c-core
+and other utilities:
+
++ struct i2c_device_id example_idtable[] = {
++       { "example", 0 },
++       { }
++};
++
++MODULE_DEVICE_TABLE(i2c, example_idtable);
+
+static struct i2c_driver example_driver = {
+ 	.driver		= {
+		.owner		= THIS_MODULE,
+		.name		= "example",
+	},
++	.id_table	= example_ids,
+
+
+Our driver should now look like this:
+
+struct example_state {
+	struct i2c_client	*client;
+	....
+};
+
+static int example_probe(struct i2c_client *client,
+		     	 const struct i2c_device_id *id)
+{
+	struct example_state *state;
+	struct device *dev = &client->dev;
+
+	state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+	if (state == NULL) {
+		dev_err(dev, "failed to create our state\n");
+		return -ENOMEM;
+	}
+
+	state->client = client;
+	i2c_set_clientdata(client, state);
+
+	/* rest of the initialisation goes here. */
+
+	dev_info(dev, "example client created\n");
+
+	return 0;
+}
+
+static int __devexit example_remove(struct i2c_client *client)
+{
+	struct example_state *state = i2c_get_clientdata(client);
+
+	kfree(state);
+	return 0;
+}
+
+static struct i2c_device_id example_idtable[] = {
+	{ "example", 0 },
+	{ }
+};
+
+MODULE_DEVICE_TABLE(i2c, example_idtable);
+
+static struct i2c_driver example_driver = {
+ 	.driver		= {
+		.owner		= THIS_MODULE,
+		.name		= "example",
+	},
+	.id_table	= example_idtable,
+	.probe		= example_probe,
+	.remove		= __devexit_p(example_remove),
+	.suspend	= example_suspend,
+	.resume		= example_resume,
+};

Subject: [PATCH 728/788] ipwireless: Do not return value from sending funcs

ipwireless: Do not return value from sending funcs

Do not return value from do_send_fragment and do_send_packet, it's not used.
The packet size checks are not useful too:

* zero length packet will never be sent, caller always passes packet_header
  size which is either 1 or 3
* MTU check is done in caller, no need to repeat

ipwireless: Explicitly request io and mem regions

Documentation/pcmcia/driver-changes.txt says, that driver should call request_region
for used memory/io regions since PCMCIA does not do this (since 2.6.8).

Subject: [PATCH 731/788] ipwireless: Increase PPP outgoing queue size

ipwireless: Increase PPP outgoing queue size

Increase default size of PPP outgoing queue. Currently set to 1, which
means that a packet quickly following another pushed by PPP must wait
until hardware actually sends the previous and PPP has to be waken up
by ppp_wakeup(). This slows down upstream.

Now PPP can push more packets at once which get buffered inside driver
and pushed immediatelly to hardware when previous packet is out.

Experiments show that size = 10 is quite good for all connection types
(GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads.
Need for higher queue size than 10 occures in only < 0.1 % of cases.

Subject: [PATCH 734/788] ACPI/CPUIDLE: prevent setting pm_idle to NULL

pm_idle_save resp. pm_idle_old can be NULL when the restore code in
acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler()
is called. This can set pm_idle unconditinally to NULL, which causes the
kernel to panic when calling pm_idle in the x86 idle code. This was
covered by an extra check for !pm_idle in the x86 idle code, which was
removed during the x86 idle code refactoring.

Instead of restoring the pm_idle check in the x86 code prevent the
acpi/cpuidle code to set pm_idle to NULL.

Reported by: Dhaval Giani http://lkml.org/lkml/2008/7/2/309
Based on a debug patch from Ingo Molnar

Subject: [PATCH 741/788] cpu masks: optimize and clean up cpumask_of_cpu()

Clean up and optimize cpumask_of_cpu(), by sharing all the zero words.

Instead of stupidly generating all possible i=0...NR_CPUS 2^i patterns
creating a huge array of constant bitmasks, realize that the zero words
can be shared.

In other words, on a 64-bit architecture, we only ever need 64 of these
arrays - with a different bit set in one single world (with enough zero
words around it so that we can create any bitmask by just offsetting in
that big array). And then we just put enough zeroes around it that we
can point every single cpumask to be one of those things.

So when we have 4k CPU's, instead of having 4k arrays (of 4k bits each,
with one bit set in each array - 2MB memory total), we have exactly 64
arrays instead, each 8k bits in size (64kB total).

And then we just point cpumask(n) to the right position (which we can
calculate dynamically). Once we have the right arrays, getting
"cpumask(n)" ends up being:

  static inline const cpumask_t *get_cpu_mask(unsigned int cpu)
  {
          const unsigned long *p = cpu_bit_bitmap[1 + cpu % BITS_PER_LONG];
          p -= cpu / BITS_PER_LONG;
          return (const cpumask_t *)p;
  }

This brings other advantages and simplifications as well:

 - we are not wasting memory that is just filled with a single bit in
   various different places

 - we don't need all those games to re-create the arrays in some dense
   format, because they're already going to be dense enough.

if we compile a kernel for up to 4k CPU's, "wasting" that 64kB of memory
is a non-issue (especially since by doing this "overlapping" trick we
probably get better cache behaviour anyway).

[ mingo@elte.hu:

  Converted Linus's mails into a commit. See:

     http://lkml.org/lkml/2008/7/27/156
     http://lkml.org/lkml/2008/7/28/320

  Also applied a family filter - which also has the side-effect of leaving
  out the bits where Linus calls me an idio... Oh, never mind ;-)

Subject: [PATCH 742/788] PCI: rewrite PCI BAR reading code

Factor out the code to read one BAR from the loop in pci_read_bases into
a new function, __pci_read_base.  The new code is slightly more
readable, better commented and removes the ifdef.

Subject: [PATCH 743/788] PCI: handle 64-bit resources better on 32-bit

If the kernel is configured to support 64-bit resources on a 32-bit
machine, we can support 64-bit BARs properly.  Just change the condition
to check sizeof(resource_size_t) instead of BITS_PER_LONG.

Subject: [PATCH 744/788] PCI MSI: Don't disable MSIs if the mask bit isn't
 supported

David Vrabel has a device which generates an interrupt storm on the INTx
pin if we disable MSI interrupts altogether.  Masking interrupts is only
a performance optimisation, so we can ignore the request to mask the
interrupt.

Subject: [PATCH 748/788] PCI: fix bogus "'device' may be used uninitialized"
 warning in pci_slot

I get warnings about 'device' possibly being used uninitialised.  While
I can deduce this is not true, it seems that GCC can't.  This patch
changes `check_slot' to return device on success and -1 on error, which
shuts GCC up.

Subject: [PATCH 749/788] PCI: add D3 power state avoidance quirk

Libata has some hacks to deal with certain controllers going silly in D3
state. The right way to handle this is to keep a PCI device flag for
such devices. That can then be generalised for no ATA devices with power
problems.

Convert printks to use dev_printk().

I converted DBG() to dev_dbg().  This DBG() is from arch/x86/pci/pci.h and
requires source-code modification to enable, so dev_dbg() seems roughly
equivalent.

Subject: [PATCH 752/788] mfd: add platform_data to mfd_cell

Adding platform_data to mfd_cell allows passing of platform data directly
to the platform_device created for each cell and thus reuse of existing
drivers.
On the other side it can be used as a hook to mfd_cell itself
removing the need in mfd_get_cell method.

Subject: [PATCH 753/788] exec: include pagemap.h again to fix build

Fix compilation errors on avr32 and without CONFIG_SWAP, introduced by
ba92a43dbaee339cf5915ef766d3d3ffbaaf103c ("exec: remove some includes")

  In file included from include/asm/tlb.h:24,
                   from fs/exec.c:55:
  include/asm-generic/tlb.h: In function 'tlb_flush_mmu':
  include/asm-generic/tlb.h:76: error: implicit declaration of function 'release_pages'
  include/asm-generic/tlb.h: In function 'tlb_remove_page':
  include/asm-generic/tlb.h:105: error: implicit declaration of function 'page_cache_release'
  make[1]: *** [fs/exec.o] Error 1

This straightforward part-revert is nobody's favourite patch to address
the underlying tlb.h needs swap.h needs pagemap.h (but sparc won't like
that) mess; but appropriate to fix the build now before any overhaul.

Subject: [PATCH 754/788] tmpfs: fix kernel BUG in shmem_delete_inode

SuSE's insserve initscript ordering program hits kernel BUG at mm/shmem.c:814
on 2.6.26.  It's using posix_fadvise on directories, and the shmem_readpage
method added in 2.6.23 is letting POSIX_FADV_WILLNEED allocate useless pages
to a tmpfs directory, incrementing i_blocks count but never decrementing it.

Fix this by assigning shmem_aops (pointing to readpage and writepage and
set_page_dirty) only when it's needed, on a regular file or a long symlink.

Many thanks to Kel for outstanding bugreport and steps to reproduce it.

Subject: [PATCH 758/788] mmu-notifiers: add mm_take_all_locks() operation

mm_take_all_locks holds off reclaim from an entire mm_struct.  This allows
mmu notifiers to register into the mm at any time with the guarantee that
no mmu operation is in progress on the mm.

This operation locks against the VM for all pte/vma/mm related operations
that could ever happen on a certain mm.  This includes vmtruncate,
try_to_unmap, and all page faults.

The caller must take the mmap_sem in write mode before calling
mm_take_all_locks().  The caller isn't allowed to release the mmap_sem
until mm_drop_all_locks() returns.

mmap_sem in write mode is required in order to block all operations that
could modify pagetables and free pages without need of altering the vma
layout (for example populate_range() with nonlinear vmas).  It's also
needed in write mode to avoid new anon_vmas to be associated with existing
vmas.

A single task can't take more than one mm_take_all_locks() in a row or it
would deadlock.

mm_take_all_locks() and mm_drop_all_locks are expensive operations that
may have to take thousand of locks.

mm_take_all_locks() can fail if it's interrupted by signals.

When mmu_notifier_register returns, we must be sure that the driver is
notified if some task is in the middle of a vmtruncate for the 'mm' where
the mmu notifier was registered (mmu_notifier_invalidate_range_start/end
is run around the vmtruncation but mmu_notifier_register can run after
mmu_notifier_invalidate_range_start and before
mmu_notifier_invalidate_range_end).  Same problem for rmap paths.  And
we've to remove page pinning to avoid replicating the tlb_gather logic
inside KVM (and GRU doesn't work well with page pinning regardless of
needing tlb_gather), so without mm_take_all_locks when vmtruncate frees
the page, kvm would have no way to notice that it mapped into sptes a page
that is going into the freelist without a chance of any further
mmu_notifier notification.

Subject: [PATCH 759/788] mmu-notifiers: core

With KVM/GFP/XPMEM there isn't just the primary CPU MMU pointing to pages.
 There are secondary MMUs (with secondary sptes and secondary tlbs) too.
sptes in the kvm case are shadow pagetables, but when I say spte in
mmu-notifier context, I mean "secondary pte".  In GRU case there's no
actual secondary pte and there's only a secondary tlb because the GRU
secondary MMU has no knowledge about sptes and every secondary tlb miss
event in the MMU always generates a page fault that has to be resolved by
the CPU (this is not the case of KVM where the a secondary tlb miss will
walk sptes in hardware and it will refill the secondary tlb transparently
to software if the corresponding spte is present).  The same way
zap_page_range has to invalidate the pte before freeing the page, the spte
(and secondary tlb) must also be invalidated before any page is freed and
reused.

Currently we take a page_count pin on every page mapped by sptes, but that
means the pages can't be swapped whenever they're mapped by any spte
because they're part of the guest working set.  Furthermore a spte unmap
event can immediately lead to a page to be freed when the pin is released
(so requiring the same complex and relatively slow tlb_gather smp safe
logic we have in zap_page_range and that can be avoided completely if the
spte unmap event doesn't require an unpin of the page previously mapped in
the secondary MMU).

The mmu notifiers allow kvm/GRU/XPMEM to attach to the tsk->mm and know
when the VM is swapping or freeing or doing anything on the primary MMU so
that the secondary MMU code can drop sptes before the pages are freed,
avoiding all page pinning and allowing 100% reliable swapping of guest
physical address space.  Furthermore it avoids the code that teardown the
mappings of the secondary MMU, to implement a logic like tlb_gather in
zap_page_range that would require many IPI to flush other cpu tlbs, for
each fixed number of spte unmapped.

To make an example: if what happens on the primary MMU is a protection
downgrade (from writeable to wrprotect) the secondary MMU mappings will be
invalidated, and the next secondary-mmu-page-fault will call
get_user_pages and trigger a do_wp_page through get_user_pages if it
called get_user_pages with write=1, and it'll re-establishing an updated
spte or secondary-tlb-mapping on the copied page.  Or it will setup a
readonly spte or readonly tlb mapping if it's a guest-read, if it calls
get_user_pages with write=0.  This is just an example.

This allows to map any page pointed by any pte (and in turn visible in the
primary CPU MMU), into a secondary MMU (be it a pure tlb like GRU, or an
full MMU with both sptes and secondary-tlb like the shadow-pagetable layer
with kvm), or a remote DMA in software like XPMEM (hence needing of
schedule in XPMEM code to send the invalidate to the remote node, while no
need to schedule in kvm/gru as it's an immediate event like invalidating
primary-mmu pte).

At least for KVM without this patch it's impossible to swap guests
reliably.  And having this feature and removing the page pin allows
several other optimizations that simplify life considerably.

Dependencies:

1) mm_take_all_locks() to register the mmu notifier when the whole VM
   isn't doing anything with "mm".  This allows mmu notifier users to keep
   track if the VM is in the middle of the invalidate_range_begin/end
   critical section with an atomic counter incraese in range_begin and
   decreased in range_end.  No secondary MMU page fault is allowed to map
   any spte or secondary tlb reference, while the VM is in the middle of
   range_begin/end as any page returned by get_user_pages in that critical
   section could later immediately be freed without any further
   ->invalidate_page notification (invalidate_range_begin/end works on
   ranges and ->invalidate_page isn't called immediately before freeing
   the page).  To stop all page freeing and pagetable overwrites the
   mmap_sem must be taken in write mode and all other anon_vma/i_mmap
   locks must be taken too.

2) It'd be a waste to add branches in the VM if nobody could possibly
   run KVM/GRU/XPMEM on the kernel, so mmu notifiers will only enabled if
   CONFIG_KVM=m/y.  In the current kernel kvm won't yet take advantage of
   mmu notifiers, but this already allows to compile a KVM external module
   against a kernel with mmu notifiers enabled and from the next pull from
   kvm.git we'll start using them.  And GRU/XPMEM will also be able to
   continue the development by enabling KVM=m in their config, until they
   submit all GRU/XPMEM GPLv2 code to the mainline kernel.  Then they can
   also enable MMU_NOTIFIERS in the same way KVM does it (even if KVM=n).
   This guarantees nobody selects MMU_NOTIFIER=y if KVM and GRU and XPMEM
   are all =n.

The mmu_notifier_register call can fail because mm_take_all_locks may be
interrupted by a signal and return -EINTR.  Because mmu_notifier_reigster
is used when a driver startup, a failure can be gracefully handled.  Here
an example of the change applied to kvm to register the mmu notifiers.
Usually when a driver startups other allocations are required anyway and
-ENOMEM failure paths exists already.

 struct  kvm *kvm_arch_create_vm(void)
 {
        struct kvm *kvm = kzalloc(sizeof(struct kvm), GFP_KERNEL);
+       int err;

        if (!kvm)
                return ERR_PTR(-ENOMEM);

        INIT_LIST_HEAD(&kvm->arch.active_mmu_pages);

+       kvm->arch.mmu_notifier.ops = &kvm_mmu_notifier_ops;
+       err = mmu_notifier_register(&kvm->arch.mmu_notifier, current->mm);
+       if (err) {
+               kfree(kvm);
+               return ERR_PTR(err);
+       }
+
        return kvm;
 }

mmu_notifier_unregister returns void and it's reliable.

The patch also adds a few needed but missing includes that would prevent
kernel to compile after these changes on non-x86 archs (x86 didn't need
them by luck).

Subject: [PATCH 761/788] mpc52xx_psc_spi: fix block transfer

The block transfer routine in the mpc52xx psc spi driver misinterpret
the datasheet.  According to the processor datasheet the chipselect is
held as long as the EOF is not written.

Theoretically blocks of any sizes can be transferred in this way.  The
old routine however writes an EOF after every word, which has the size
of size_of_word.  This makes the transfer slow.

Also fixed some duplicate code.

Subject: [PATCH 762/788] spi_s3c24xx: really assign busnum

The original "Pass the bus number we expect the S3C24XX SPI driver to
attach to via the platform data." [1] patch was mis-sent, and missed two
important parts of the diff, which was to actually set the bus_num field
and add the relevant field to the platform data.

The previous commit 50f426b55d919dd017af35bb6a08753d1f262920 promised to
add a bus_num field, but failed to include the two hunks that added this
field to include/asm-arm/arch-s3c2410/spi.h and then pass it to the spi
core when creating the new master field in drivers/spi/spi_s3c24xx.c.

Subject: [PATCH 764/788] vfs: pagecache usage optimization for
 pagesize!=blocksize

When we read some part of a file through pagecache, if there is a
pagecache of corresponding index but this page is not uptodate, read IO
is issued and this page will be uptodate.

I think this is good for pagesize == blocksize environment but there is
room for improvement on pagesize != blocksize environment.  Because in
this case a page can have multiple buffers and even if a page is not
uptodate, some buffers can be uptodate.

So I suggest that when all buffers which correspond to a part of a file
that we want to read are uptodate, use this pagecache and copy data from
this pagecache to user buffer even if a page is not uptodate.  This can
reduce read IO and improve system throughput.

I wrote a benchmark program and got result number with this program.

This benchmark do:

  1: mount and open a test file.

  2: create a 512MB file.

  3: close a file and umount.

  4: mount and again open a test file.

  5: pwrite randomly 300000 times on a test file.  offset is aligned
     by IO size(1024bytes).

  6: measure time of preading randomly 100000 times on a test file.

The result was:
	2.6.26
        330 sec

	2.6.26-patched
        226 sec

Arch:i386
Filesystem:ext3
Blocksize:1024 bytes
Memory: 1GB

On ext3/4, a file is written through buffer/block.  So random read/write
mixed workloads or random read after random write workloads are optimized
with this patch under pagesize != blocksize environment.  This test result
showed this.

The benchmark program is as follows:

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
#include <time.h>
#include <stdlib.h>
#include <string.h>
#include <sys/mount.h>

#define LEN 1024
#define LOOP 1024*512 /* 512MB */

main(void)
{
	unsigned long i, offset, filesize;
	int fd;
	char buf[LEN];
	time_t t1, t2;

	if (mount("/dev/sda1", "/root/test1/", "ext3", 0, 0) < 0) {
		perror("cannot mount\n");
		exit(1);
	}
	memset(buf, 0, LEN);
	fd = open("/root/test1/testfile", O_CREAT|O_RDWR|O_TRUNC);
	if (fd < 0) {
		perror("cannot open file\n");
		exit(1);
	}
	for (i = 0; i < LOOP; i++)
		write(fd, buf, LEN);
	close(fd);
	if (umount("/root/test1/") < 0) {
		perror("cannot umount\n");
		exit(1);
	}
	if (mount("/dev/sda1", "/root/test1/", "ext3", 0, 0) < 0) {
		perror("cannot mount\n");
		exit(1);
	}
	fd = open("/root/test1/testfile", O_RDWR);
	if (fd < 0) {
		perror("cannot open file\n");
		exit(1);
	}

	filesize = LEN * LOOP;
	for (i = 0; i < 300000; i++){
		offset = (random() % filesize) & (~(LEN - 1));
		pwrite(fd, buf, LEN, offset);
	}
	printf("start test\n");
	time(&t1);
	for (i = 0; i < 100000; i++){
		offset = (random() % filesize) & (~(LEN - 1));
		pread(fd, buf, LEN, offset);
	}
	time(&t2);
	printf("%ld sec\n", t2-t1);
	close(fd);
	if (umount("/root/test1/") < 0) {
		perror("cannot umount\n");
		exit(1);
	}

I got section mismatch message about bio_integrity_init_slab().

WARNING: fs/built-in.o(__ksymtab+0xb60): Section mismatch in reference from the variable __ksymtab_bio_integrity_init_slab to the function .init.text:bio_integrity_init_slab()

The symbol bio_integrity_init_slab is exported and annotated __init Fix
this by removing the __init annotation of bio_integrity_init_slab or drop
the export.

It only call from init_bio().  The EXPORT_SYMBOL() can be removed.

Subject: [PATCH 767/788] eCryptfs: use page_alloc not kmalloc to get a page of
 memory

With SLUB debugging turned on in 2.6.26, I was getting memory corruption
when testing eCryptfs.  The root cause turned out to be that eCryptfs was
doing kmalloc(PAGE_CACHE_SIZE); virt_to_page() and treating that as a nice
page-aligned chunk of memory.  But at least with SLUB debugging on, this
is not always true, and the page we get from virt_to_page does not
necessarily match the PAGE_CACHE_SIZE worth of memory we got from kmalloc.

My simple testcase was 2 loops doing "rm -f fileX; cp /tmp/fileX ." for 2
different multi-megabyte files.  With this change I no longer see the
corruption.

    XEN PV and lguest may need to assign max_pfn_mapped too.

But no CC.  Yinghai, wasting fellow developers' time is a VERY bad
habit.  If you do it again, I will hunt you down and try to extract
the three hours of my life I just lost :)

Ron Minnich noticed that guest userspace gets a GPF when it tries to int3:
we need to copy the privilege level from the guest-supplied IDT to the real
IDT.  int3 is the only common case where guest userspace expects to invoke
an interrupt, so that's the symptom of failing to do this.

Subject: [PATCH 776/788] lguest: Support assigning a MAC address

If you've got a nice DHCP configuration which maps MAC
addresses to specific IP addresses, then you're going to
want to start your guest with one of those MAC addresses.

Also, in Fedora, we have persistent network interface naming
based on the MAC address, so with randomly assigned
addresses you're soon going to hit eth13. Who knows what
will happen then!

Allow assigning a MAC address to the network interface with
e.g.

  --tunnet=bridge:eth0:00:FF:95:6B:DA:3D

or:

  --tunnet=192.168.121.1:00:FF:95:6B:DA:3D

which is pretty unintelligable, but ...

(includes Rusty's minor rework)

Subject: [PATCH 781/788] lguest: Tell Guest net not to notify us on every
 packet xmit

virtio_ring has the ability to suppress notifications.  This prevents
a guest exit for every packet, but we need to set a timer on packet
receipt to re-check if there were any remaining packets.

Here are the times for 1G TCP Guest->Host with different timeout
settings (it matters because the TCP window doesn't grow big enough to
fill the entire buffer):

Timeout value	Seconds		Xmit/Recv/Timeout
None (before)	25.3784		xmit 7750233 recv 1
2500 usec	62.5119		xmit 207020 recv 2 timeout 207020
1000 usec	34.5379		xmit 207003 recv 2 timeout 207003
750 usec	29.2305		xmit 207002 recv 1 timeout 207002
500 usec	19.1887		xmit 561141 recv 1 timeout 559657
250 usec	20.0465		xmit 214128 recv 2 timeout 214110
100 usec	19.2583		xmit 561621 recv 1 timeout 560153

(Note that these values are sensitive to the GSO patches which come
 later, and probably other traffic-related variables, so take with a
 large grain of salt).

Subject: [PATCH 782/788] lguest: Adaptive timeout

Since the correct timeout value varies, use a heuristic which adjusts
the timeout depending on how many packets we've seen.  This gives
slightly worse results, but doesn't need tweaking when GSO is
introduced.

Subject: [PATCH 786/788] lguest: turn Waker into a thread, not a process

lguest uses a Waker process to break it out of the kernel (ie.
actually running the guest) when file descriptor needs attention.

Changing this from a process to a thread somewhat simplifies things:
it can directly access the fd_set of things to watch.  More
importantly, it means that the Waker can see Guest memory correctly,
so /dev/vring file descriptors will work as anticipated (the
alternative is to actually mmap MAP_SHARED, but you can't do that with
/dev/zero).

Subject: [PATCH 787/788] Fix 'get_user_pages_fast()' with non-page-aligned
 start address

Alexey Dobriyan reported trouble with LTP with the new fast-gup code,
and Johannes Weiner debugged it to non-page-aligned addresses, where the
new get_user_pages_fast() code would do all the wrong things, including
just traversing past the end of the requested area due to 'addr' never
matching 'end' exactly.

This is not a pretty fix, and we may actually want to move the alignment
into generic code, leaving just the core code per-arch, but Alexey
verified that the vmsplice01 LTP test doesn't crash with this.
