Merge tag 'drm-intel-next-2013-08-09' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Daniel writes:
New pile of stuff for -next:
- Cleanup of the old crtc helper callbacks, all encoders are now converted
  to the i915 modeset infrastructure.
- Massive amount of wm patches from Ville for ilk, snb, ivb, hsw, this is
  prep work to eventually get things going for nuclear pageflips where we
  need to adjust watermarks on the fly.
- More vm/vma patches from Ben. This refactoring isn't yet fully rolled
  out, we miss the execbuf conversion and some of the low-level
  bind/unbind support code.
- Convert our hdmi infoframe code to use the new common helper functions
  (Damien). This contains some bugfixes for the common infoframe helpers.
- Some cruft removal from Damien.
- Various smaller bits&pieces all over, as usual.
