Merge branch 'drm-next-4.10' of git://people.freedesktop.org/~agd5f/linux into drm-next
First new feature pull for 4.10. Highlights: - Support for multple virtual displays in the virtual dce component - New VM mgr to support non-contiguous vram buffers - Support for UVD powergating on additional asics - Power management improvements - lots of code cleanup and bug fixes * 'drm-next-4.10' of git://people.freedesktop.org/~agd5f/linux: (107 commits) drm/amdgpu: turn on/off uvd clock when dpm enable/disable on CI drm/amdgpu: disable dpm before turn off clock when vce idle. drm/amdgpu: enable uvd bypass mode for CI/VI. drm/amdgpu: just not load smc firmware if smu is already running drm/amdgpu: when suspend, set boot state instand of disable dpm. drm/amdgpu: use failed label to handle context init failure drm/amdgpu: add amdgpu_ttm_bo_eviction_valuable callback drm/ttm: make eviction decision a driver callback v2 drm/ttm: fix coding style in ttm_bo_driver.h drm/radeon/pm: autoswitch power state when in balanced mode drm/amd/powerplay: fix spelling mistake and add KERN_WARNING to printks drm/amdgpu:new ids flag for preempt drm/amdgpu: mark symbols static where possible drm/amdgpu: change function declarations and add missing header dependencies drm/amdgpu: s/amdgpuCrtc/amdgpu_crtc/ in pageflip code drm/amdgpu/atom: remove a bunch of unused functions drm/amdgpu: consolidate atom scratch reg handling for hangs drm/amdgpu: use amdgpu_bo_[create|free]_kernel for wb drm/amdgpu: add VCE VM session tracking drm/amdgpu: improve parse_cs handling a bit ...
