Merge branch 'drm-next-3.7' of git://people.freedesktop.org/~agd5f/linux into drm-next

Alex writes:
"The big changes for 3.7 include:
- Asynchronous VM page table updates for Cayman/SI
- 2 level VM page table support.  Saves memory compared to 1 level
  page tables.
- Reworked PLL handing in the display code allows lots more
  combinations of monitors to work, including more than two
  DP displays assuming compatible clocks across shared PLLs.
  This also allows us to power down extra PLLs when we can
  share a single one across multiple displays which saves power.
- Native backlight control on ATOMBIOS systems.
- Improved ACPI support for interacting with the GPU.  Fixes
  backlight control on some laptops.
- Document AMD ACPI interfaces
- Lots of code cleanup
- Bug fixes"
