Merge branch 'drm-prime-dmabuf-initial' of git://people.freedesktop.org/~airlied/linux

Pull dma-buf prime support from Dave Airlie:
 "This isn't a majorly urgent thing to have, but we'd like to set the
  stage for working on dma-buf support in the drm drivers for the next
  merge window, so I'd like to push in the initial submission now so
  people have something that we can build on top of.  The code just
  introduces the user interface and internal helper functions for
  drivers to use.

  We have driver support under development for i915, nouveau, udl on x86
  and exynos, omapdrm on arm, which we would be aiming for the next
  merge window."

In the -rc1 announcement I asked for people who would use this to
comment on it, and got severa "Yes please" from people for this and for
HSI (that I merged earlier).

So far crickets on pohmelfs and the DMA-mapping infrastructure.
