      Pull power management fixes from Rafael Wysocki:
 "These revert a recent change in the schedutil cpufreq governor that
  had not been expected to make any functional difference, but turned
  out to introduce a performance regression, fix an initialization issue
  in the amd-pstate driver and make it actually replace the venerable
  ACPI cpufreq driver on the supported systems by default.

  Specifics:

   - Revert a recent schedutil cpufreq governor change that introduced a
     performace regression on Pixel 6 (Sam Wu)

   - Fix amd-pstate driver initialization after running the kernel via
     kexec (Wyes Karny)

   - Turn amd-pstate into a built-in driver which allows it to take
     precedence over acpi-cpufreq by default on supported systems and
     amend it with a mechanism to disable this behavior (Perry Yuan)

   - Update amd-pstate documentation in accordance with the other
     changes made to it (Perry Yuan)"

 "Weekly fixes, amdgpu has not quite settled down.

  Most of the changes are small, and the non-amdgpu ones are all fine.
  There are a bunch of DP MST DSC fixes that fix some issues introduced
  in a previous larger MST rework.

  The biggest one is mainly propagating some error values properly
  instead of bool returns, and I think it just looks large but doesn't
  really change anything too much, except propagating errors that are
  required to avoid deadlocks. I've gone over it and a few others and
  they've had some decent testing over the last few weeks.

  Summary:

  amdgpu:
   - amdgpu gang submit fix
   - DCN 3.1.4 fixes
   - DP MST DSC deadlock fixes
   - HMM userptr fixes
   - Fix Aldebaran CU occupancy reporting
   - GFX11 fixes
   - PSP suspend/resume fix
   - DCE12 KASAN fix
   - DCN 3.2.x fixes
   - Rotated cursor fix
   - SMU 13.x fix
   - DELL platform suspend/resume fixes
   - VCN4 SR-IOV fix
   - Display regression fix for polled connectors

   - Never purge busy TTM objects
   - Fix warn in intel_display_power_*_domain() functions

      Linus Torvalds authored 
      Pull 9p fixes from Dominique Martinet:

 - 9p now uses a variable size for its recv buffer, but every place
   hadn't been updated properly to use it and some buffer overflows have
   been found and needed fixing.

   There's still one place where msize is incorrectly used in a safety
   check (p9_check_errors), but all paths leading to it should already
   be avoiding overflows and that patch took a bit more time to get
   right for zero-copy requests so I'll send it for 6.2

 - yet another race condition in p9_conn_cancel introduced by a fix for
   a syzbot report in the same place. Maybe at some point we'll get it
   right without burning it all down...

      fscache: fix OOB Read in __fscache_acquire_volume · 9f0933ac
      David Howells authored 
      The type of a->key[0] is char in fscache_volume_same().  If the length
of cache volume key is greater than 127, the value of a->key[0] is less
than 0.  In this case, klen becomes much larger than 255 after type
conversion, because the type of klen is size_t.  As a result, memcmp()
is read out of bounds.

This causes a slab-out-of-bounds Read in __fscache_acquire_volume(), as
reported by Syzbot.

Fix this by changing the type of the stored key to "u8 *" rather than
"char *" (it isn't a simple string anyway).  Also put in a check that
the volume name doesn't exceed NAME_MAX.

ASoC: Fixes for v6.1

A clutch of small fixes that have come in in the past week, people seem
to have been unusually active for this late in the release cycle.  The
most critical one here is the fix to renumber the SOF DAI types in order
to restore ABI compatibility which was broken by the addition of AMD
support.
