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

Last pile of stuff for 3.7, essentially just a bunch of bigger fixes and a
few less intrusive features:

- cpu freq interface in sysfs from Ben
- cpu edp fixes and some related cleanups
- write-combining ptes for pre-gen6 (Chris)
- basic CADL support (Peter Wu), this fixes quite a few issues with
  backlights ...
- rework of the gem backing pages handling (preps for stolen mem handling)
  from Chris
- some more cleanup-fallout from the modeset-rework

On top of that I've done a backmerge of -rc7(since the conflicts got too
messy and I've pushed out broken merged trees too often). I've also
included 3 fixes on top of what QA beat on:

- Fix for a infoframe handling regression in 3.5 - infoframe blows up too
  often and 3.6 is pretty much done, so I'd like to merge that through
  -next and the stable process and give it more exposure before it lands
  in a stable tree.
- ioctl cosmetics^Wspelling fix in the structs (userspace won't be
  affected, since all existing userspace uses private copies of the ioctl
  struct definitions, and the struct layout itself is abi compatible).
- Bugfix for a regression introduced in this pull's testing cycle.
