Alex writes:
"This is the first -fixes pull for 3.7.  I would have preferred
to have gotten it out a bit sooner, but I was on holiday last week.
- Cleanup of the new 2 level page table code it get it in
  better shape and using less memory.
- Fix some display issues related to the PLL rework.
- Fix some cmpiler warnings and errors with certain config
  options.
- Other misc bug fixes."

  drm/radeon: fix spelling typos in debugging output
  drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().
  drm/radeon: check if pcie gen 2 is already enabled (v2)
  drm/radeon/cayman: set VM max pfn at MC init
  drm/radeon: separate pt alloc from lru add
  drm/radeon: don't add the IB pool to all VMs v2
  drm/radeon: allocate page tables on demand v4
  drm/radeon: update comments to clarify VM setup (v2)
  drm/radeon: allocate PPLLs from low to high
