Merge branch 'drm-next-3.8' of git://people.freedesktop.org/~agd5f/linux into drm-next

Alex writes:
Pretty minor -next pull request.  We some additional new bits waiting
internally for release.  Hopefully Monday we can get at least some of
them out.  The others will probably take a few more weeks.

Highlights of the current request:
- ELD registers for passing audio information to the sound hardware
- Handle GPUVM page faults more gracefully
- Misc fixes
