     address space infrastructure (not enabled)

   - msm:

     power management, hdmi audio support

   - nouveau:

     ongoing GPU fault recovery, initial maxwell support, random fixes

   - exynos:

     refactored driver to clean up a lot of abstraction, DP support
     moved into drm, LVDS bridge support added, parallel panel support

   - gma500:

     SGX MMU support, SGX irq handling, asle irq work fixes
