Merge tag 'drm-intel-fixes-2014-01-08' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes 

Just a revert (gen4 backlight seems a lost cause) and a tlb coherency fix
for bdw, plus the patch to sign up Jani for co-maintainer. Thanks to Ben
for taking care of -fixes while I've enjoyed a bit of vacation.
