Merge tag 'drm-intel-next-fixes-2014-10-03' of git://anongit.freedesktop.org/drm-intel into drm-next
Bunch of fixes for 3.18. Major parts:
- ppgtt fixes (but full ppgtt is for 3.19) from Chris, Michel, ...
- hdmi pixel replication fixes (Clint Taylor)
- leftover i830M patches from Ville
- small things all over
