…drm/xe/kernel into drm-next

UAPI Changes:
 - Add mmap support for PCI memory barrier (Tejas, Matthew Auld)
 - Enable integration with perf pmu, exposing event counters: for now, just
   GT C6 residency (Vinay, Lucas)

   firmware upgrade on critical failures (Riana, Rodrigo)

   Meteor Lake and Lunar Lake (Daniele, John Harrison)
 - Expose package and vram temperature over hwmon subsystem (Raag, Badal, Rodrigo)

Cross-subsystem Changes:
 - Backmege drm-next to synchronize with i915 display and other internal APIs

Display Changes (including i915):
 - Device probe re-order to help with flicker-free boot (Maarten)
 - Align watermark, hpd and dsm with i915 (Rodrigo)
 - Better abstraction for d3cold (Rodrigo)

Driver Changes:
 - Make sure changes to ccs_mode is with helper for gt sync reset (Maciej)
 - Drop mmio_ext abstraction since it didn't prove useful in its current form
   (Matt Roper)
 - Reject BO eviction if BO is bound to current VM (Oak, Thomas Hellström)
 - Add GuC Power Conservation debugfs (Rodrigo)
 - L3 cache topology updates for Xe3 (Francois, Matt Atwood)
 - Better logging about missing GuC logs (John Harrison)
 - Better logging for hwconfig-related data availability (John Harrison)
 - Tracepoint updates for xe_bo_create, xe_vm and xe_vma (Oak)
 - Add missing SPDX licenses (Francois)
 - Xe suballocator imporovements (Michal Wajdeczko)
 - Improve logging for native vs SR-IOV driver mode (Satyanarayana)
 - Make sure VF bootstrap is not attempted in execlist mode (Maarten)
 - Add GuC Buffer Cache abstraction for some CTB H2G actions and use
   during VF provisioning (Michal Wajdeczko)
 - Better synchronization in gtidle for new users (Vinay)
 - New workarounds for Panther Lake (Nirmoy, Vinay)
 - PCI ID updates for Panther Lake (Matt Atwood)
 - Enable SR-IOV for Panther Lake (Michal Wajdeczko)
 - Update MAINTAINERS to stop directing xe changes to drm-misc (Lucas)
 - New PCI IDs for Battle Mage (Shekhar)
 - Better pagefault logging (Francois)
 - SR-IOV fixes and refactors for past and new platforms (Michal Wajdeczko)
 - Platform descriptor refactors and updates (Sai Teja)
 - Add gt stats debugfs (Francois)
 - Add guc_log debugfs to dump to dmesg (Lucas)
 - Abstract per-platform LMTT availability (Piotr Piórkowski)
 - Refactor VRAM manager location (Piotr Piórkowski)
 - Add missing xe_pm_runtime_put when forcing wedged mode (Shuicheng)
 - Fix possible lockup when forcing wedged mode (Xin Wang)
 - Probe refactors to use cleanup actions with better error handling (Lucas)
 - XE_IOCTL_DBG clarification for userspace (Maarten)
 - Better xe_mmio initialization and abstraction (Ilia)
 - Drop unnecessary GT lookup (Matt Roper)
 - Skip client engine usage from fdinfo for VFs (Marcin Bernatowicz)
 - Allow to test xe_sync_entry_parse with error injection (Priyanka)
 - OA fix for polled read (Umesh)
