[Joonas Lahtinen]

Hi Dave & Sima,

Mostly fixes in this drm-intel-gt-next PR at this time.

One thing to pay attention is the limitation of number of relocations to
INT_MAX which might impact synthetic tests, but no real workloads.

Regards, Joonas

UAPI Changes:

- drm/i915: 2 GiB of relocations ought to be enough for anybody*

  Limit the number of relocations to INT_MAX.

  Only impact should be onsynthetic tests.

Driver Changes:

- Fix for #11396: GPU Hang and rcs0 reset on Cherrytrail platform
- Fix Virtual Memory mapping boundaries calculation (Andi)
- Fix for #11255: Long hangs in buddy allocator with DG2/A380 without
  Resizable BAR since 6.9 (David)
- Mark the GT as dead when mmio is unreliable (Chris, Andi)
- Workaround additions / fixes for MTL, ARL and DG2 (John H, Nitin)
- Enable partial memory mapping of GPU virtual memory (Andi, Chris)

- Prevent NULL deref on intel_memory_regions_hw_probe (Jonathan, Dan)
- Avoid UAF on intel_engines_release (Krzysztof)

- Don't update PWR_CLK_STATE starting Gen12 (Umesh)
- Code and dmesg cleanups (Andi, Jesus, Luca)

The following changes since commit 3b85152cb167bd24fe84ceb91b719b5904ca354f:
