Pull drm fixes from Dave Airlie:
 "Weekly drm fixes, I'll be honest and say I think this is larger than
  I'd prefer at this point, the main blow out point is that xe has two
  larger fixes.

  One is a fix for active context utilisation reporting, it's for a
  reported regression and will end up in stable anyways, so I don't see
  any point in holding it up.

  The second is a fix for mixed cpu/gpu atomics, which are currently
  broken, but are also not something your average desktop/laptop user is
  going to hit in normal operation, and having them fixed now is better
  than threading them through stable later.

  Other than those, it's mostly the usual, a bunch of amdgpu randoms and
  a few other minor fixes.

  dma-buf:
   - Avoid memory reordering in fence handling

  meson:
   - Avoid integer overflow in mode-clock calculations

  panel-mipi-dbi:
   - Fix output with drm_client_setup_with_fourcc()

  amdgpu:
   - Fix CSA unmap
   - Fix MALL size reporting on GFX11.5
   - AUX fix
   - DCN 3.5 fix
   - VRR fix
   - DP MST fix
   - DML 2.1 fixes
   - Silence DP AUX spam
   - DCN 4.0.1 cursor fix
   - VCN 4.0.5 fix

  ivpu:
   - Fix buffer size in debugfs code

  gpuvm:
   - Add timeslicing and allocation restriction for SVM

  xe:
   - Fix shrinker debugfs name
   - Add HW workaround to Xe2
   - Fix SVM when mixing GPU and CPU atomics
   - Fix per client engine utilization due to active contexts not saving
     timestamp with lite restore enabled"
