Merge branch 'drm-next-3.19' of git://people.freedesktop.org/~agd5f/linux into drm-next

Radeon patches for 3.19.  Christian has a number of GPUVM improvements
slated as well, but I'd like to wait until he gets back to work next week
to pull those in. Highlights of this pull:
- ttm performance improvements
- CI dpm fixes
