[Intel-gfx] [PULL] drm vblank timestamping changes

[Ville Syrjälä]

Hi Dave,

Here's the vblank timestamp pull request you wanted.

I addressed the few bugs that Mario pointed out and added
the r-bs.

As it has been a while since I made the changes, I gave it a
quick spin on a few different i915 machines. Fortunately
everything still seems to be fine.

The following changes since commit cfd72a4c2089aa3938f37281a34d6eb3306d5fd8:

  Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next (2014-01-20 10:21:54 +1000)
