Yang Li 3c995c4c75 crypto: cavium/nitrox - Remove redundant initialization of 'sg'
Pointer 'sg' is being initialized however this value is never
read as 'sg' is assigned a same value in for_each_sg().
Remove the redundant assignment.

Corentin Labbe dfb098d692 crypto: ixp4xx - fallback when having more than one SG
Testing ixp4xx_crypto lead to:
alg: skcipher: ecb(des)-ixp4xx encryption overran dst buffer on test vector 0, cfg="two even aligned splits"

The HW overwrites destination always when sg_nents() > 1.
The problem seems that the HW always write areq->cryptlen bytes on the
last SG.
A comment in driver's code seems to give a clue that multiple SG was not
planned "This was never tested by Intel for more than one dst buffer, I think".
So let's add a fallback for this situation.

Thara Gopinath 6c34e446b2 crypto: qce - Make result dump optional
Qualcomm crypto engine allows for IV registers and status register
to be concatenated to the output. This option is enabled by setting the
RESULTS_DUMP field in GOPROC  register. This is useful for most of the
algorithms to either retrieve status of operation or in case of
authentication algorithms to retrieve the mac. But for ccm
algorithms, the mac is part of the output stream and not retrieved
from the IV registers, thus needing a separate buffer to retrieve it.
Make enabling RESULTS_DUMP field optional so that algorithms can choose
whether or not to enable the option.
Note that in this patch, the enabled algorithms always choose
RESULTS_DUMP to be enabled. But later with the introduction of ccm
algorithms, this changes.

Annotate the firmware files CCP might need using MODULE_FIRMWARE().
This will get them included into an initrd when CCP is also included
there. Otherwise the CCP module will not find its firmware when loaded

This can cause problems when the pre-loaded SEV firmware is too old to
support current SEV and SEV-ES virtualization features.

Linus Torvalds 6dae40aed4 fbmem: fix horribly incorrect placement of __maybe_unused
Commit b9d79e4ca4 ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.

It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

    drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes]
    static const struct __maybe_unused seq_operations proc_fb_seq_ops = {
                        ^

Linus Torvalds 9819f682e4 A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup move.  A
    recent commit combined two PSI callbacks to reduce the number of cgroup
    tree updates, but missed that schedule() can drop rq::lock for load
    balancing, which opens the race window for cgroup_move_task() which then
    observes half updated state. The fix is to solely use task::ps_flags
    instead of looking at the potentially mismatching scheduler state
 
  - Prevent an out-of-bounds access in uclamp caused bu a rounding division
    which can lead to an off-by-one error exceeding the buckets array size.
 
  - Prevent unfairness caused by missing load decay when a task is attached

Pull scheduler fixes from Thomas Gleixner:
 "A set of scheduler updates:

   - Prevent PSI state corruption when schedule() races with cgroup
     move.

     A recent commit combined two PSI callbacks to reduce the number of
     cgroup tree updates, but missed that schedule() can drop rq::lock
     for load balancing, which opens the race window for
     cgroup_move_task() which then observes half updated state.

     The fix is to solely use task::ps_flags instead of looking at the
     potentially mismatching scheduler state

   - Prevent an out-of-bounds access in uclamp caused bu a rounding
     division which can lead to an off-by-one error exceeding the
     buckets array size.

   - Prevent unfairness caused by missing load decay when a task is
     attached to a cfs runqueue.

     The old load of the task was attached to the runqueue and never
     removed. Fix it by enforcing the load update through the hierarchy

Linus Torvalds 732a27a089 A set of locking related fixes and updates:
- Two fixes for the futex syscall related to the timeout handling.
 
     FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
     it's not set the time namespace adjustment for clock MONOTONIC is
     applied wrongly.
 
     FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
     always a relative timeout.

Linus Torvalds fec4d42724 drm/i915/display: fix compiler warning about array overrun
intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().

End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer.  gcc-11 correctly warns
about this case:

  drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_check_mst_status’:
  drivers/gpu/drm/i915/display/intel_dp.c:3491:22: warning: ‘drm_dp_channel_eq_ok’ reading 6 bytes from a region of size 4 [-Wstringop-overread]

        |      ^~~~~~~~~~~~~~~~~~~~
       6:14 elapsed

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.

There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use
random data off the stack.

Steve French c1f8a398b6 smb3: if max_channels set to more than one channel request multichannel
Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

server doesn't support multichannel we should not be attempting it.

Steve French 679971e721 smb3: when mounting with multichannel include it in requested capabilities
In the SMB3/SMB3.1.1 negotiate protocol request, we are supposed to
advertise CAP_MULTICHANNEL capability when establishing multiple
channels has been requested by the user doing the mount. See MS-SMB2
sections 2.2.3 and 3.2.5.2

Without setting it there is some risk that multichannel could fail
if the server interpreted the field strictly.

Masahiro Yamada 0ab1438bad linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>
<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.

IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.

Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.

Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.
