With this commit:
2a0788dc9bc4 x86: Use clflushopt in drm_clflush_virt_range
If clflushopt is available on the system, we use it instead of clflush
in drm_clflush_virt_range. There were two calls to clflush in this
function, but only one was changed to clflushopt. This patch changes
the other clflush call to clflushopt.

I'll forward it eventually to Dave for 3.16. But if someone else steals it
beforehand I don't mind ;-)

This was merged through -tip, right? The DRM tree does not include the
initial patches, yet, so I'd recommend merging this through -tip
again. I've put hpa on CC for that. However, I cannot see where the
initial patch was sent to, so can you resent it properly to lkml,
please? And please also put the respective maintainers on CC.
Thanks
David
