Pull drm fixes from Dave Airlie:
 "While this is large for rc8 time but also AI driven fixes is a lot of
  it, we had a more traditional screw up, and a regression was just
  found in the fair scheduling patches that went in back in rc1. This
  reverts the fair scheduler back to an option and sets the default back
  to what it should have been. We might have been a bit overly zealous
  in switching over, but at least it feels more normal than the AI
  driven fixes.

  Apart from the scheduler, it's mostly amdgpu and xe fixes, with some
  misc fixes to the log code and connector code.

  scheduler:
   - revert fair scheduler patches due to regression
   - mark fair as experimental

  connector:
   - fix OOB read in hdmi audio infoframe

  log:
   - fix divide by 0 if module param is set to 0
   - fix OOB read on empty message
   - fix infinite loop for too large scale

  xe:
   - Fix DPT Allocation paths
   - Fixes around UM queue BO
   - Order ring writes before ring tail updates
   - Add termination on resume for PXP
   - Document Sentinel and make CTX_TIMESTAMP read TOCTOU-safe
   - Fix sync entry leak on OA config emit failure
   - Check managed mutex initilization errors
   - Fix min frequency setting
   - Fix xe_device_probe error path

  amdgpu:
   - Bounds checking fix in CS IOCTL
   - Bounds checking fix in GEM IOCTL
   - Display fixes
   - GPUVM fix
   - ASPM fix
   - UVD bounds checking fixes
   - VCE 3 fix
   - BT.2020 fixes
   - NBIF 6.3.1 fix
   - IP discovery fix

  radeon:
   - Runtime pm fix

  amdxdna:
   - skip attempting to populate unmapped pages"
