Pull ARM SoC fixes for SPEAr from Olof Johansson:
 "These are arriving very late in the release cycle, but there has been
  a change of maintainers on the SPEAr platform and they have needed a
  while to get going.

  The patch count is higher than I would like at this point, but they're
  all relevant fixes and well-contained in their own platform code.  I
  still think it's suitable 3.5 material and I don't think it should
  increase the need for a -rc8 since they are so contained."

On spear320 device supported mode are:

   * AUTO_NET_SMII_MODE
   * AUTO_NET_MII_MODE
   * AUTO_EXP_MODE
   * SMALL_PRINTERS_MODE
   * EXTENDED_MODE

spear320-evb board is designed for EXTENDED_MODE only, hence it does not
boot correctly in current form where pinctrl part for some devices fail.

Configure and boot the SPEAr320 evaluation board in EXTENDED_MODE.

sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl
register bit no. 23:25, with following possibilities

   0XX: pll1_clk
   10X: sys_synth_clk
   110: pll2_clk
   111: pll3_clk

Out of several possibilities (h/w wise) to select same clock parent for
sys_clk, current clock implementation was considering just one value.

When bootloader programmed different (valid) value to select a clock
parent then Linux breaks.

Here, we try to include all possibilities which can lead to same
clock selection thus making Linux independent of bootloader selection
values.

Merge Andrew's remaining patches for 3.5:
 "Nine fixes"

* Merge emailed patches from Andrew Morton <akpm@linux-foundation.org>: (9 commits)
  mm: fix lost kswapd wakeup in kswapd_stop()
  m32r: make memset() global for CONFIG_KERNEL_BZIP2=y

  mn10300: fix "pull clearing RESTORE_SIGMASK into block_sigmask()" fallout
  bootmem: make ___alloc_bootmem_node_nopanic() really nopanic

Offlining memory may block forever, waiting for kswapd() to wake up
because kswapd() does not check the event kthread->should_stop before
sleeping.

The proper pattern, from Documentation/memory-barriers.txt, is:

   ---  waker  ---
   event_indicated = 1;
   wake_up_process(event_daemon);

   ---  sleeper  ---
   for (;;) {
      set_current_state(TASK_UNINTERRUPTIBLE);
      if (event_indicated)
         break;
      schedule();
   }

   set_current_state() may be wrapped by:
      prepare_to_wait();

In the kswapd() case, event_indicated is kthread->should_stop.

  === offlining memory (waker) ===
   kswapd_stop()
      kthread_stop()
         kthread->should_stop = 1
         wake_up_process()
         wait_for_completion()

  ===  kswapd_try_to_sleep (sleeper) ===
   kswapd_try_to_sleep()
      prepare_to_wait()
           .
           .
      schedule()
           .
           .
      finish_wait()

The schedule() needs to be protected by a test of kthread->should_stop,
which is wrapped by kthread_should_stop().

Reproducer:
   Do heavy file I/O in background.
   Do a memory offline/online in a tight loop

| while backporting the below patch, I realised that your fix busted

| allocation failure but when the usemap size was too large such that
| goal + size > limit triggers the BUG_ON in the bootmem allocator.  So
| we need a version that passes limit ONLY if the usemap is smaller than

after checking the code, the name of ___alloc_bootmem_node_nopanic()
does not reflect the fact.

Make bootmem really not panic.

Hope will kill bootmem sooner.

  PM: Rename CAP_EPOLLWAKEUP to CAP_BLOCK_SUSPEND

As discussed in
http://thread.gmane.org/gmane.linux.kernel/1249726/focus=1288990

,
the capability introduced in 4d7e30d9
to govern EPOLLWAKEUP seems misnamed: this capability is about governing
the ability to suspend the system, not using a particular API flag
(EPOLLWAKEUP). We should make the name of the capability more general
to encourage reuse in related cases. (Whether or not this capability
should also be used to govern the use of /sys/power/wake_lock is a
question that needs to be separately resolved.)

This patch renames the capability to CAP_BLOCK_SUSPEND. In order to ensure
that the old capability name doesn't make it out into the wild, could you
please apply and push up the tree to ensure that it is incorporated
for the 3.5 release.

   b) 3.4 commit can cause ip_vs_control_cleanup to be invoked after
      the ipvs_core_ops are unregistered during rmmod (Julian ANastasov)

    (Alexander Duyck)

    GFP flag is not being retained for the allocation (Eric Dumazet).

 8) Missing NULL hceck in sch_sfb netlink message parsing (Alan Cox)

 9) bnx2 crashes because TX index iteration is not bounded correctly
    (Michael Chan)

10) IPoIB generates warnings in TCP queue collapsing (via
    skb_try_coalesce) because it does not set skb->truesize correctly
    (Eric Dumazet)

11) vlan_info objects leak for the implicit vlan with ID 0 (Amir
    Hanania)

12) A fix for TX time stamp handling in gianfar does not transfer socket
    ownership from one packet to another correctly, resulting in a
    socket write space imbalance (Eric Dumazet)

13) Julia Lawall found several cases where we do a list iteration, and
    then at the loop termination unconditionally assume we ended up with
    real list object, rather than the list head itself (CNIC, RXRPC,
    mISDN).

14) The bonding driver handles procfs moving incorrectly when a device
    it manages is moved from one namespace to another (Eric Biederman)

15) Missing memory barriers in stmmac descriptor accesses result in
    various crashes (Deepak Sikri)

16) Fix handling of broadcast packets in batman-adv (Simon Wunderlich)

17) Properly check the sanity of sendmsg() lengths in ieee802154's
    dgram_sendmsg().  Dave Jones and others have hit and reported this
    bug (Sasha Levin)

18) Some drivers (b44 and b43legacy) on 64-bit machines stopped working
    because of how netdev_alloc_skb() was adjusted.  Such drivers should
    now use alloc_skb() for obtaining bounce buffers.  (Eric Dumazet)

19) atl1c mis-managed it's link state in that it stops the queue by hand
    on link down.  The generic networking takes care of that and this
    double stop locks the queue down.  So simply removing the driver's
    queue stop call fixes the problem (Cloud Ren)

20) Fix out-of-memory due to mis-accounting in net_em packet scheduler
    (Eric Dumazet)

21) If DCB and SR-IOV are configured at the same time in IXGBE the chip
    will hang because this is not supported (Alexander Duyck)

22) A commit to stop drivers using netdev->base_addr broke the CNIC
    driver (Michael Chan)

23) Timeout regression in ipset caused by an attempt to fix an overflow
    bug (Jozsef Kadlecsik).

24) mac80211 minstrel code allocates memory using incorrect size
    (Thomas Huehn)

25) llcp_sock_getname() needs to check for a NULL device otherwise we
    OOPS (Sasha Levin)

26) mwifiex leaks memory (Bing Zhao)

====================
I know that we're in fairly late stage to request pulls, but the IPVS people
pinged me with little patches with oops fixes last week.

One of them was recently introduced (during the 3.4 development cycle) while
cleaning up the IPVS netns support. They are:

* Fix one regression introduced in 3.4 while cleaning up the
  netns support for IPVS, from Julian Anastasov.

* Fix one oops triggered due to resetting the conntrack attached to the skb
  instead of just putting it in the forward hook, from Lin Ming. This problem
  seems to be there since 2.6.37 according to Simon Horman.

When rpmsg drivers are built into the kernel, they must not initialize
before the rpmsg bus does, otherwise they'd trigger a BUG() in
drivers/base/driver.c line 169 (driver_register()).

To fix that, and to stop depending on arbitrary linkage ordering of
those built-in rpmsg drivers, we make the rpmsg bus initialize at
subsys_initcall.

The steps to reproduce as follow,

1. On Host1, setup brige br0(192.168.1.106)
2. Boot a kvm guest(192.168.1.105) on Host1 and start httpd
3. Start IPVS service on Host1
   ipvsadm -A -t 192.168.1.106:80 -s rr
   ipvsadm -a -t 192.168.1.106:80 -r 192.168.1.105:80 -m
4. Run apache benchmark on Host2(192.168.1.101)
   ab -n 1000 http://192.168.1.106/



ip_vs_reply4
  ip_vs_out
    handle_response
      ip_vs_notrack
        nf_reset()
        {
          skb->nf_bridge = NULL;
        }

Actually, IPVS wants in this case just to replace nfct
with untracked version. So replace the nf_reset(skb) call
in ip_vs_notrack() with a nf_conntrack_put(skb->nfct) call.

This patch addresses a kernel panic seen when setting up the interface.
Specifically we see a NULL pointer dereference on the Tx descriptor cleanup
path when enabling interrupts.  This change corrects that so it cannot
occur.

As the life flows, developers priorities shifts a bit. Reflect actual
changes in the maintainership of IEEE 802.15.4 code: Sergey mostly
stopped cared about this piece of code. Most of the work recently was
done by Alexander, so put him to the MAINTAINERS file to reflect his
status and to ease the life of respective patches.

Also add new net/mac802154/ directory to the list of maintained files.

unregister_netdevice_notifier() must be called before
unregister_pernet_subsys() to avoid accessing already freed
pernet memory. This fixes the following oops when doing rmmod:

there are some out of bound accesses in netprio cgroup.

now before accessing the dev->priomap.priomap array,we only check
if the dev->priomap exist.and because we don't want to see
additional bound checkings in fast path, so we should make sure
that dev->priomap is null or array size of dev->priomap.priomap
is equal to max_prioidx + 1;

so in write_priomap logic,we should call extend_netdev_table when
dev->priomap is null and dev->priomap.priomap_len < max_len.
and in cgrp_create->update_netdev_tables logic,we should call
extend_netdev_table only when dev->priomap exist and
dev->priomap.priomap_len < max_len.

and it's not needed to call update_netdev_tables in write_priomap,
we can only allocate the net device's priomap which we change through
net_prio.ifpriomap.

this patch also add a return value for update_netdev_tables &
extend_netdev_table, so when new_priomap is allocated failed,
write_priomap will stop to access the priomap,and return -ENOMEM
back to the userspace to tell the user what happend.

Change From v3:
1. add rtnl protect when reading max_prioidx in write_priomap.

2. only call extend_netdev_table when map->priomap_len < max_len,
   this will make sure array size of dev->map->priomap always
   bigger than any prioidx.

3. add a function write_update_netdev_table to make codes clear.

Change From v2:
1. protect extend_netdev_table by RTNL.
2. when extend_netdev_table failed,call dev_put to reduce device's refcount.

The commit 4197aa7b implements 64 bit
per ring statistics. But the driver resets the 'total_bytes' and
'total_packets' from RX and TX rings in the RX and TX interrupt
handlers to zero. This results in statistics being lost and user space
reporting RX and TX statistics as zero. This patch addresses the
issue by preventing the resetting of RX and TX ring statistics to
zero.
