this is the next pull request for stashed up radeon fixes for 3.15. This is finally calming down with only four patches in this pull request.

* 'drm-fixes-3.15' of git://people.freedesktop.org/~deathsimple/linux:
  drm/radeon: only allocate necessary size for vm bo list
  drm/radeon: don't allow RADEON_GEM_DOMAIN_CPU for command submission
  drm/radeon: avoid crash if VM command submission isn't available
  drm/radeon: lower the ref * post PLL maximum once more
