Merge branch 'drm-fixes-4.3' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
radeon and amdgpu fixes for 4.3. It's a bit bigger than usual since it's 3 weeks worth of fixes since I was on vacation, then at XDC. - lots of stability fixes - suspend and resume fixes - GPU scheduler fixes - Misc other fixes * 'drm-fixes-4.3' of git://people.freedesktop.org/~agd5f/linux: (31 commits) drm/radeon: add quirk for MSI R7 370 drm/amdgpu: Sprinkle drm_modeset_lock_all to appease locking checks drm/radeon: Sprinkle drm_modeset_lock_all to appease locking checks drm/amdgpu: sync ce and me with SWITCH_BUFFER(2) drm/amdgpu: integer overflow in amdgpu_mode_dumb_create() drm/amdgpu: info leak in amdgpu_gem_metadata_ioctl() drm/amdgpu: integer overflow in amdgpu_info_ioctl() drm/amdgpu: unwind properly in amdgpu_cs_parser_init() drm/amdgpu: Fix max_vblank_count value for current display engines drm/amdgpu: use kmemdup rather than duplicating its implementation drm/amdgpu: fix UVD suspend and resume for VI APU drm/amdgpu: fix the UVD suspend sequence order drm/amdgpu: make UVD handle checking more strict drm/amdgpu: Disable UVD PG drm/amdgpu: more scheduler cleanups v2 drm/amdgpu: cleanup fence queue init v2 drm/amdgpu: rename fence->scheduler to sched v2 drm/amdgpu: cleanup entity init drm/amdgpu: refine the scheduler job type conversion drm/amdgpu: refine the job naming for amdgpu_job and amdgpu_sched_job ...
