The newly added SPI device ID table does not work because the
entry is incorrectly copied from the OF device table.

During build testing, this shows as a compile failure when building
it as a loadable module:

drivers/misc/eeprom/eeprom_93xx46.c:424:1: error: redefinition of '__mod_of__eeprom_93xx46_of_table_device_table'
MODULE_DEVICE_TABLE(of, eeprom_93xx46_of_table);

If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic

 *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0);

will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we
subtract one from that making a large number that is then shifted more than the
number of bits that fit into an unsigned long.

  habanalabs: fix resetting args in wait for CS IOCTL

In commit b212921b ("elf: don't use MAP_FIXED_NOREPLACE for elf
executable mappings") we still leave MAP_FIXED_NOREPLACE in place for
load_elf_interp.

Unfortunately, this will cause kernel to fail to start with:

    1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already
    Failed to execute /init (error -17)

The reason is that the elf interpreter (ld.so) has overlapping segments.

The reason for this problem is the same as described in commit
ad55eac7 ("elf: enforce MAP_FIXED on overlaying elf segments").

Not only executable binaries, elf interpreters (e.g. ld.so) can have
overlapping elf segments, so we better drop MAP_FIXED_NOREPLACE and go
back to MAP_FIXED in load_elf_interp.

The objtool warning that the kvm instruction emulation code triggered
wasn't very useful:

    arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception

in that it helpfully tells you which symbol name it had trouble figuring
out the relocation for, but it doesn't actually say what the unknown
symbol type was that triggered it all.

In this case it was because of missing type information (type 0, aka
STT_NOTYPE), but on the whole it really should just have printed that
out as part of the message.

Because if this warning triggers, that's very much the first thing you
want to know - why did reloc2sec_off() return failure for that symbol?

So rather than just saying you can't handle some type of symbol without
saying what the type _was_, just print out the type number too.

The recent change to make objtool aware of more symbol relocation types
(commit 24ff6525: "objtool: Teach get_alt_entry() about more
relocation types") also added another check, and resulted in this
objtool warning when building kvm on x86:

    arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception

The reason seems to be that kvm_fastop_exception() is marked as a global
symbol, which causes the relocation to ke kept around for objtool.  And
at the same time, the kvm_fastop_exception definition (which is done as
an inline asm statement) doesn't actually set the type of the global,
which then makes objtool unhappy.

The minimal fix is to just not mark kvm_fastop_exception as being a
global symbol.  It's only used in that one compilation unit anyway, so
it was always pointless.  That's how all the other local exception table
labels are done.

I'm not entirely happy about the kinds of games that the kvm code plays
with doing its own exception handling, and the fact that it confused
objtool is most definitely a symptom of the code being a bit too subtle
and ad-hoc.  But at least this trivial one-liner makes objtool no longer
upset about what is going on.

Pull block fixes from Jens Axboe:
 "A few block fixes for this release:

   - Revert a BFQ commit that causes breakage for people. Unfortunately
     it was auto-selected for stable as well, so now 5.14.7 suffers from
     it too. Hopefully stable will pick up this revert quickly too, so
     we can remove the issue on that end as well.

   - Add a quirk for Apple NVMe controllers, which due to their
     non-compliance broke due to the introduction of command sequences
     (Keith)

   - Use shifts in nbd, fixing a __divdi3 issue (Nick)"

Pull io_uring fixes from Jens Axboe:
 "Two fixes in here:

   - The signal issue that was discussed start of this week (me).

   - Kill dead fasync support in io_uring. Looks like it was broken
     since io_uring was initially merged, and given that nobody has ever
     complained about it, let's just kill it (Pavel)"

 "A fix for a regression added this cycle in the pmem driver, and for a
  long standing bug for failed NUMA node lookups on ARM64.

  This has appeared in -next for several days with no reported issues.

  Summary:

   - Fix a regression that caused the sysfs ABI for pmem block devices
     to not be registered. This fails the nvdimm unit tests and dax
     xfstests.

   - Fix numa node lookups for dax-kmem memory (device-dax memory

In cachefiles_mark_object_buried, the dentry in question may not have an
owner, and thus our cachefiles_object pointer may be NULL when calling
the tracepoint, in which case we will also not have a valid debug_id to
print in the tracepoint.

Check for NULL object in the tracepoint and if so, just set debug_id to
MAX_UINT as was done in 2908f5e1 ("fscache: Add a cookie debug ID
and use that in traces").

This fixes the following oops:

    FS-Cache: Cache "mycache" added (type cachefiles)
    CacheFiles: File cache on vdc registered
    ...
    Workqueue: fscache_object fscache_object_work_func [fscache]

5.15-rc1 crashes with blank screen when booting up on two ThinkPads
using i915.  Bisections converge convincingly, but arrive at different
and suprising "culprits", none of them the actual culprit.

netconsole (with init_netconsole() hacked to call i915_init() when
logging has started, instead of by module_init()) tells the story:

kernel BUG at drivers/gpu/drm/i915/i915_sw_fence.c:245!
with RSI: ffffffff814d408b pointing to sw_fence_dummy_notify().
I've been building with CONFIG_CC_OPTIMIZE_FOR_SIZE=y, and that

If driver read tmp value sufficient for

from device then Null pointer dereference occurs.
(It is possible if tmp = 0b0xyz1xyz, where same literals mean same numbers)
Also lm75[] does not serve a purpose anymore after switching to
devm_i2c_new_dummy_device() in w83791d_detect_subclients().

The bytes for max_power_out from the ibm-cffps devices differ in byte
order for some power supplies.

The Witherspoon power supply returns the bytes in MSB/LSB order.

The Rainier power supply returns the bytes in LSB/MSB order.

The Witherspoon power supply uses version cffps1. The Rainier power
supply should use version cffps2. If version is cffps1, swap the bytes
before output to max_power_out.

Tested:
    Witherspoon before: 3148. Witherspoon after: 3148.
    Rainier before: 53255. Rainier after: 2000.

Because Rui is now going to focus on work that is not related to the
maintenance of the thermal subsystem in the kernel, Rafael will start
to help Daniel with handling the development process as a new member
of the thermal maintainers team.  Rui will continue to review patches
in that area.

The thermal development process flow will change so that the material
from the thermal git tree will be merged into the thermal branch of
the linux-pm.git tree before going into the mainline.

Update the information in MAINTAINERS accordingly.
