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. We still have a few patches that deal with lack of MAPPABLE_APERTURE support, though we can probably split that into its own series. Patches 1-2 are just noise. Patches 3-6 are the basic intel_memory_region bits + basic mock_selftests. Patches 7-11 are the basic LMEM region bits + basic live_selftests. Patches 12-14 try to turn stolen + shmem into intel_region_regions. Patches 15-21 implement the !MAPPABLE_APERTURE bits. The fake LMEM patch allows us to run the live_selftests with LMEM enabled and !HAS_MAPPABLE_APERTURE in CI.
