Pull drm fixes from Dave Airlie:
 "Things seemed to have quieten down, though no i915 pull (I even gave
  them an extra 12 hours in case they were late).

  The amdgpu floating point fix is probably the largest, but it just
  moves some code around to it doesn't do fpu stuff outside the fpu
  boundaries. Otherwise it's just a couple of vmwgfx fixes (maintainer
  change) and two etnaviv fixes.

  vmwgfx:
   - change maintainers
   - fix redundant assignment
   - fix parameter name
   - fix return value

  etnaviv:
   - memory leak fix when userspace passes a invalid softpin address
   - off-by-one crashing the kernel in the perfmon domain iteration when
     the GPU core has both 2D and 3D capabilities

  amdgpu:
   - DP fix
   - Floating point fix
   - Fix cursor stutter issue"
