Merge branch 'drm-fixes-4.6' of git://people.freedesktop.org/~agd5f/linux into drm-fixes

A few fixes for 4.6.
- revert amdgpu PX commit that was previously reverted on the radeon side
- cleaned up version of the NI+ MC update display fix for radeon
- TTM kref fix

* 'drm-fixes-4.6' of git://people.freedesktop.org/~agd5f/linux:
  drm/amdgpu: disable vm interrupts with vm_fault_stop=2
  drm/amdgpu: print a message if ATPX dGPU power control is missing
  Revert "drm/amdgpu: disable runtime pm on PX laptops without dGPU power control"
  drm/radeon: fix vertical bars appear on monitor (v2)
  drm/ttm: fix kref count mess in ttm_bo_move_to_lru_tail
