[git pull] drm dma-buf prime support

[Dave Airlie]

Hi Linus,

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.

Dave.
