Merge branch 'drm-fixes' of git://

Pull drm fixes from Dave Airlie:
 "Radeon, imx, msm, and i915 fixes.

  The msm, imx and i915 ones are fairly run of the mill.

  Radeon had some DP audio and posting reads for irq fixes, along with a
  fix for 32-bit kernels with new cards, we were using unsigned long to
  represent GPU side memory space, but since that changed size on 32 vs
  64 cards with lots of VRAM failed, so the change has no effect on
  x86-64, just moves to using uint64_t instead"
