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] * tag 'drm-intel-next-2013-07-26-fixed' of git://people.freedesktop.org/~danvet/drm-intel: (289 commits) drm/i915: Do not dereference NULL crtc or fb until after checking drm/i915: fix pnv display core clock readout out drm/i915: Replace open-coded offset_in_page() drm/i915: Retry DP aux_ch communications with a different clock after failure drm/i915: Add messages useful for HPD storm detection debugging (v2) drm/i915: dvo_ch7xxx: fix vsync polarity setting drm/i915: fix the racy object accounting drm/i915: Convert the register access tracepoint to be conditional drm/i915: Squash gen lookup through multiple indirections inside GT access drm/i915: Use the common register access functions for NOTRACE variants drm/i915: Use a private interface for register access within GT drm/i915: Colocate all GT access routines in the same file drm/i915: fix reference counting in i915_gem_create drm/i915: Use Graphics Base of Stolen Memory on all gen3+ drm/i915: disable stolen mem for OVERLAY_NEEDS_PHYSICAL drm/i915: add functions to disable and restore LCPLL drm/i915: disable CLKOUT_DP when it's not needed drm/i915: extend lpt_enable_clkout_dp drm/i915: fix up error cleanup in i915_gem_object_bind_to_gtt drm/i915: Add some debug breadcrumbs to connector detection ...
