Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This is probably a bit big, but just because I fell behind last week
  and didn't get to doing any pulls, so stuff backed up behind me, I
  actually should have sent this for -rc3 but failed to even manage
  that.

  So this has radeon, intel, nouveau, vmware, exynos and tegra fixes in
  it, and the line count isn't all the bad in the end"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (50 commits)
  drm: fix the addition of the side-by-side (half) flag for extra 3D modes
