Merge tag 'drm-intel-next-2012-12-21' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Daniel writes: - seqno wrap fixes and debug infrastructure from Mika Kuoppala and Chris Wilson - some leftover kill-agp on gen6+ patches from Ben - hotplug improvements from Damien - clear fb when allocated from stolen, avoids dirt on the fbcon (Chris) - Stolen mem support from Chris Wilson, one of the many steps to get to real fastboot support. - Some DDI code cleanups from Paulo. - Some refactorings around lvds and dp code. - some random little bits&pieces * tag 'drm-intel-next-2012-12-21' of git://people.freedesktop.org/~danvet/drm-intel: (93 commits) drm/i915: Return the real error code from intel_set_mode() drm/i915: Make GSM void drm/i915: Move GSM mapping into dev_priv drm/i915: Move even more gtt code to i915_gem_gtt drm/i915: Make next_seqno debugs entry to use i915_gem_set_seqno drm/i915: Introduce i915_gem_set_seqno() drm/i915: Always clear semaphore mboxes on seqno wrap drm/i915: Initialize hardware semaphore state on ring init drm/i915: Introduce ring set_seqno drm/i915: Missed conversion to gtt_pte_t drm/i915: Bug on unsupported swizzled platforms drm/i915: BUG() if fences are used on unsupported platform drm/i915: fixup overlay stolen memory leak drm/i915: clean up PIPECONF bpc #defines drm/i915: add intel_dp_set_signal_levels drm/i915: remove leftover display.update_wm assignment drm/i915: check for the PCH when setting pch_transcoder drm/i915: Clear the stolen fb before enabling drm/i915: Access to snooped system memory through the GTT is incoherent drm/i915: Remove stale comment about intel_dp_detect() ...
