Pull drm fixes from Dave Airlie:
 "This one has a core mst fix and two i915 fixes. amdgpu just enables
  some hw outside experimental.

  The panfrost fix is a little bigger than I'd like at this stage but it
  fixes a fairly fundamental problem with global shared buffers in that
  driver, and since it's confined to that driver and I've taken a look
  at it, I think it's fine to get into the tree now, so it can get
  stable propagated as well.

  core/mst:
   - Fix SST branch device handling

  amdgpu:
   - enable renoir outside experimental

  i915:
   - Avoid overflow with huge userptr objects
   - uAPI fix to correctly handle negative values in
     engine->uabi_class/instance (cc: stable)

  panfrost:
   - Fix mapping of globally visible BO's (Boris)"
