[Intel-gfx] [PATCH v3 0/5] Asynchronous flip implementation for i915

[Karthik B S <karthik.b.s@intel.com>]

Without async flip support in the kernel, fullscreen apps where game
resolution is equal to the screen resolution, must perform an extra blit
per frame prior to flipping.

Asynchronous page flips will also boost the FPS of Mesa benchmarks.

v2: Few patches have been squashed and patches have been shuffled as
    per the reviews on the previous version.
