Merge tag 'drm-intel-gt-next-2021-06-10' of git://anongit.freedesktop.org/drm/drm-intel into drm-next

UAPI Changes:

- Disable mmap ioctl for gen12+ (excl. TGL-LP)
- Start enabling HuC loading by default for upcoming Gen12+
  platforms (excludes TGL and RKL)

Core Changes:

- Backmerge of drm-next

Driver Changes:

- Revert "i915: use io_mapping_map_user" (Eero, Matt A)
- Initialize the TTM device and memory managers (Thomas)
- Major rework to the GuC submission backend to prepare
  for enabling on new platforms (Michal Wa., Daniele,
  Matt B, Rodrigo)
- Fix i915_sg_page_sizes to record dma segments rather
  than physical pages (Thomas)

- Locking rework to prep for TTM conversion (Thomas)
- Replace IS_GEN and friends with GRAPHICS_VER (Lucas)
- Use DEVICE_ATTR_RO macro (Yue)
- Static code checker fixes (Zhihao)
