#     Pull drm fixes from Dave Airlie:
#      "Just some fixes for this week: amdgpu, radeon and i915.
#     
#       The main i915 one is a regression Gen7 (Ivybridge/Haswell), this moves
#       them back from trying to use the full-ppgtt support to the aliasing
#       version it used to use due to gpu hangs. Otherwise it's pretty quiet.
#     
#       amdgpu:
#        - Drop DRIVER_USE_AGP
#        - Fix memory leak in GPU reset
#        - Resume fix for raven
#     
#       radeon:
#        - Drop DRIVER_USE_AGP
#     
#       i915:
#        - downgrade gen7 back to aliasing-ppgtt to avoid GPU hangs
#        - shrinker fix
#        - pmu leak and double free fixes
#        - gvt user after free and virtual display reset fixes
#        - randconfig build fix"
