Merge tag 'drm-next-2020-04-10' of git://anongit.freedesktop.org/drm/drm

Pull more drm fixes from Dave Airlie:
 "As expected, more fixes did turn up in the latter part of the week.

  The drm_local_map build regression fix is here, along with temporary
  disabling of the hugepage work due to some amdgpu related crashes.

  Otherwise it's just a bunch of i915, and amdgpu fixes.

  legacy:
   - fix drm_local_map.offset type

  ttm:
   - temporarily disable hugepages to debug amdgpu problems.

  prime:
   - fix sg extraction

  amdgpu:
   - Various Renoir fixes
   - Fix gfx clockgating sequence on gfx10
   - RAS fixes
   - Avoid MST property creation after registration
   - Various cursor/viewport fixes
   - Fix a confusing log message about optional firmwares

  i915:
   - Flush all the reloc_gpu batch (Chris)
   - Ignore readonly failures when updating relocs (Chris)
   - Fill all the unused space in the GGTT (Chris)
   - Return the right vswing table (Jose)
   - Don't enable DDI IO power on a TypeC port in TBT mode for ICL+ (Imre)

  analogix_dp:
   - probe fix

  virtio:
   - oob fix in object create"
