Merge tag 'drm-intel-next-2013-07-26-fixed' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Neat that QA (and Ben) keeps on humming along while I'm on vacation, so
you already get the next feature pull request:
- proper eLLC support for HSW from Ben
- more interrupt refactoring
- add w/a tags where we implement them already (Damien)
- hangcheck fixes (Chris) + hangcheck stats (Mika)
- flesh out the new vm structs for ppgtt and ggtt (Ben)
- PSR for Haswell, still disabled by default (Rodrigo et al.)
- pc8+ refclock sequence code from Paulo
- more interrupt refactoring from Paulo, unifying ilk/snb with the ivb/hsw
  interrupt code
- full solution for the Haswell concurrent reg access issues (Chris)
- fix racy object accounting, used by some new leak tests
- fix sync polarity settings on ch7xxx dvo encoder
- random bits&pieces, little fixes and better debug output all over

[airlied: fix conflict with drm_mm cleanups]
