Merge remote branch 'korg/drm-core-next' into drm-next-stage
* korg/drm-core-next: drm/ttm: handle OOM in ttm_tt_swapout drm/radeon/kms/atom: fix shr/shl ops drm/kms: fix spelling of "CLOCK" drm/kms: fix fb_changed = true else statement drivers/gpu/drm/drm_fb_helper.c: don't use private implementation of atoi() drm: switch all GEM/KMS ioctls to unlocked ioctl status. Use drm_gem_object_[handle_]unreference_unlocked where possible drm: introduce drm_gem_object_[handle_]unreference_unlocked
