Merge drm/drm-next into drm-intel-gt-next

Maarten requested a backmerge due his work depending on subtle semantic
changes introduced by:

  7e2e69ed ("drm/i915: Fix i915_request fence wait semantics")
  2cbb8d4d ("drm/i915: use new iterator in i915_gem_object_wait_reservation")

Both should probably have been merged to drm-intel-gt-next anyway.
