Merge branch 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux into drm-next
Some additional fixes for 4.9:
- The rest of Christian's GTT rework which fixes a long standing bug
in the GPUVM code among other things
- Changes to the pci shutdown callbacks for certain hypervisors
- Fix hpd interrupt storms on eDP panels which have the hpd interrupt
enabled by the bios
- misc cleanups and bug fixes
