Merge tag 'drm-intel-fixes-2015-05-21' of git://anongit.freedesktop.org/drm-intel into drm-fixes
There's a stable backport from Ander [1] that combines this and a few
other commits to fix the flickering on v4.0, reported in [2] among
others. Having this upstream is obviously a requirement for stable.
