The basic LMEM bits, minus the uAPI, pruning, etc. The goal is to support
basic LMEM object creation within the kernel. From there we can start with the
dumb buffer support, and then the other display related bits.

Abdiel Janulgue (4):
  drm/i915: Add memory region information to device_info
  drm/i915: setup io-mapping for LMEM
  drm/i915/lmem: support kernel mapping
  drm/i915: enumerate and init each supported region

CQ Tang (1):
  drm/i915/stolen: make the object creation interface consistent

Daniele Ceraolo Spurio (4):
  drm/i915: define HAS_MAPPABLE_APERTURE
  drm/i915: do not map aperture if it is not available.
  drm/i915: set num_fence_regs to 0 if there is no aperture
  drm/i915: error capture with no ggtt slot

Matthew Auld (12):
  drm/i915: introduce intel_memory_region
  drm/i915/region: support contiguous allocations
  drm/i915/region: support volatile objects
  drm/i915: support creating LMEM objects
  drm/i915/selftests: add write-dword test for LMEM
  drm/i915/selftests: extend coverage to include LMEM huge-pages
  drm/i915: treat shmem as a region
  drm/i915: treat stolen as a region
  drm/i915: don't allocate the ring in stolen if we lack aperture
  drm/i915/selftests: fallback to using the gpu to trash stolen
  drm/i915/selftests: check for missing aperture
  HAX drm/i915: add the fake lmem region

Michal Wajdeczko (1):
  drm/i915: Don't try to place HWS in non-existing mappable region

I'm getting same igt@gem_mmap_gtt@hang failure on my display audio 
related patchset:

https://patchwork.freedesktop.org/series/67528/

... so this seems to be happening in the baseline as well...?

An artifact brought in by rc1, should be gone in a jiffie.
