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
Merge radeon test
