Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

drm-intel-next-2014-01-10:
- final bits for runtime D3 on Haswell from Paul (now enabled fully)
- parse the backlight modulation freq information in the VBT from Jani
  (but not yet used)
- more watermark improvements from Ville for ilk-ivb and bdw
- bugfixes for fastboot from Jesse
- watermark fix for i830M (but not yet everything)
- vlv vga hotplug w/a (Imre)
- piles of other small improvements, cleanups and fixes all over

Note that the pull request includes a backmerge of the last drm-fixes
pulled into Linus' tree - things where getting a bit too messy. So the
shortlog also contains a bunch of patches from Linus tree. Please yell if
you want me to frob it for you a bit.
