Merge branch 'drm-next-3.18' of git://people.freedesktop.org/~agd5f/linux into drm-next
A few more radeon patches for 3.18. This patch set gives us more
flexibility with respect to buffer placement in vram with respect
to CPU access. E.g., if you know you will not need CPU access, we can
now pin outside of the CPU window, reducing contention for the
CPU window space.
* 'drm-next-3.18' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon: add RADEON_GEM_NO_CPU_ACCESS BO creation flag (v4)
drm/radeon: Clean up assignment of TTM placement lpfn member for pinning
drm/radeon: Add RADEON_GEM_CPU_ACCESS BO creation flag
