[PATCH 0/4] Prime helpers

[Aaron Plattner]

This series adds helper functions that abstract the core parts of
.gem_prime_import and .gem_prime_export so that drivers don't have to worry
about the low-level details.  These helpers are optional.  A driver can use them
by plugging in drm_gem_prime_import and drm_gem_prime_export into the drm_driver
structure, or it can bypass them by plugging in its own functions.  The first
patch adds these helpers, and the later patches switch three drivers over to
using them.

Jerome, I tried to address your concerns about code sharing by making the
helpers available without making them required.

I haven't yet compile-tested the Exynos change since I don't have a toolchain
set up for that, but I'll try to do that today.

Aaron Plattner (4):
  drm: add prime helpers
  drm/nouveau: use prime helpers
  drm/radeon: use prime helpers
  drm/exynos: use prime helpers
