* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/anholt/drm-intel: drm/i915: fix page flip finish vs. prepare on plane B drm/i915: change default panel fitting mode to preserve aspect ratio drm/i915: fix uninitialized variable warning in i915_setup_compression() drm/i915: take struct_mutex in i915_dma_cleanup() drm/i915: Fix CRT hotplug regression in 2.6.35-rc1 i915: fix ironlake edp panel setup (v4) drm/i915: don't access FW_BLC_SELF on 965G drm/i915: Account for space on the ring buffer consumed whilst wrapping. drm/i915: gen3 page flipping fixes drm/i915: don't queue flips during a flip pending event drm/i915: Fix incorrect intel_ring_begin size in BSD ringbuffer. drm/i915: Turn on 945 self-refresh only if single CRTC is active drm/i915/gen4: Fix interrupt setup ordering drm/i915: Use RSEN instead of HTPLG for tfp410 monitor detection. drm/i915: Move non-phys cursors into the GTT Revert "drm/i915: Don't enable pipe/plane/VCO early (wait for DPMS on)." (Included the "fix page flip finish vs. prepare on plane B" patch from Jesse on top of the pull request from Eric. -- Linus)
