Merge tag 'drm-intel-next-2013-07-12' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Highlights:
- follow-up refactoring after the shared dpll rework that landed in 3.11
- oddball prep cleanups from Ben for ppgtt
- encoder->get_config state tracking infrastructure from Jesse
- used by the experimental fastboot support from Jesse (disabled by
  default)
- make the error state file official and add it to our sysfs interface
  (Mika)
- drm_mm prep changes from Ben, prepares to embedd the drm_mm_node (which
  will be used by the vma rework later on)
- interrupt handling rework, follow up cleanups to the VECS enabling, hpd
  storm handling and fifo underrun reporting.
- Big pile of smaller cleanups, code improvements and related stuff.
