Merge tag 'drm-intel-next-2013-02-01' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
Daniel writes: "Probably the last feature pull for 3.9, there's some fixes outstanding thought that I'd like to sneak in. And maybe 3.8 takes a bit longer ... Anyway, highlights of this pull: - Kill the horrible IS_DISPLAYREG hack to handle the mmio offset movements on vlv, big thanks to Ville. - Dynamic power well support for Haswell, shaves away a bit when only using the eDP port on pipe A (Paulo). Plus unclaimed register fixes uncovered by this. - Clarifications of the gpu hang/reset state transitions, hopefully fixing a few spurious -EIO deaths in userspace. - Haswell ELD fixes. - Some more (pp)gtt cleanups from Ben. - A few smaller things all over. Plus all the stuff from the previous rather small pull request: - Broadcast RBG improvements and reduced color range fixes from Ville. - Ben is on a "kill legacy gtt code for good" spree, first pile of patches included. - No-relocs and bo lut improvements for faster execbuf from Chris. - Some refactorings from Imre." * tag 'drm-intel-next-2013-02-01' of git://people.freedesktop.org/~danvet/drm-intel: (101 commits) GPU/i915: Fix acpi_bus_get_device() check in drivers/gpu/drm/i915/intel_opregion.c drm/i915: Set the SR01 "screen off" bit in i915_redisable_vga() too drm/i915: Kill IS_DISPLAYREG() drm/i915: Introduce i915_vgacntrl_reg() drm/i915: gen6_gmch_remove can be static drm/i915: dynamic Haswell display power well support drm/i915: check the power down well on assert_pipe() drm/i915: don't send DP "idle" pattern before "normal" on HSW PORT_A drm/i915: don't run hsw power well code on !hsw drm/i915: kill cargo-culted locking from power well code drm/i915: Only run idle processing from i915_gem_retire_requests_worker drm/i915: Fix CAGF for HSW drm/i915: Reclaim GTT space for failed PPGTT drm/i915: remove intel_gtt structure drm/i915: Add probe and remove to the gtt ops drm/i915: extract hw ppgtt setup/cleanup code drm/i915: pte_encode is gen6+ drm/i915: vfuncs for ppgtt drm/i915: vfuncs for gtt_clear_range/insert_entries drm/i915: Error state should print /sys/kernel/debug ...
