Merge branch 'drm-next-4.3' of git://people.freedesktop.org/~agd5f/linux into drm-next
amdgpu and radeon changes for 4.3. Highlights: - Fiji support for amdgpu. - CGS support for amdgpu. This is a new driver internal cross-component API. - Initial GPU scheduler for amdgpu. Still disabled by default. - Lots of bug fixes and optimizations * 'drm-next-4.3' of git://people.freedesktop.org/~agd5f/linux: (130 commits) drm/amdgpu: wait on page directory changes. v2 drm/amdgpu: Select BACKLIGHT_LCD_SUPPORT drm/radeon: Select BACKLIGHT_LCD_SUPPORT drm/amdgpu: cleanup sheduler rq handling v2 drm/amdgpu: move prepare work out of scheduler to cs_ioctl drm/amdgpu: fix unnecessary wake up drm/amdgpu: fix duplicated mapping invoke bug drm/amdgpu: drop bo_list_clone when no scheduler drm/amdgpu: disable GPU reset by default drm/amdgpu: fix type mismatch error drm/amdgpu: add reference for **fence drm/amdgpu: fix waiting for all fences before flipping drm/amdgpu: fix UVD return code checking drm/amdgpu: remove scheduler fence list v2 drm/amdgpu: remove amd_sched_wait_emit v2 drm/amdgpu: remove unecessary scheduler fence callbacks drm/amdgpu: fix scheduler fence implementation drm/amdgpu: don't grab dev->struct_mutex in pm functions drm/amdgpu: Don't take dev->struct_mutex in bo_force_delete drm/radeon: Don't take dev->struct_mutex in pm functions ...
