Merge remote branch 'korg/drm-radeon-next' of into drm-linus
This merges some TTM overhauls to allow us to do better object placement
for certain radeon GPUs that need scanout+cursor within range of each other,
along with an API change to not return ERESTART to userspace, but to use
ERESTARTSYS properly internally and have it convert to EINTR and catch that
correctly. Also lots of radeon fixes across the board.
