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
