Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux

Pull main drm updates from Dave Airlie:
 "This is the main merge window request for the drm.

  It's big, but jam packed will lots of features and of course 0
  regressions.  (okay maybe there'll be one).

  Highlights:

   - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
     (qemu only).  These drivers use the generic modesetting drivers.

   - initial prime/dma-buf support for i915, nouveau, radeon, udl and
     exynos

   - switcheroo audio support: so GPUs with HDMI can turn off the sound
     driver without crashing stuff.

   - There are some patches drifting outside drivers/gpu into x86 and
     EFI for better handling of multiple video adapters in Apple Macs,
     they've got correct acks except one trivial fixup.

   - Core:
	edid parser has better DMT and reduced blanking support,
	crtc properties,
	plane properties,

   - Drivers:
	exynos: add 2D core accel support, prime support, hdmi features
	intel: more Haswell support, initial Valleyview support, more
	    hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
	    cleanups and fixes
	radeon: more HDMI audio support, improved GPU lockup recovery
	    support, remove nested mutexes, less memory copying on PCIE, fix
	    bus master enable race (kexec), improved fence handling
	gma500: cleanups, 1080p support, acpi fixes
	nouveau: better nva3 memory reclocking, kepler accel (needs
	    external firmware rip), async buffer moves on nv84+ hw.

  I've some more dma-buf patches that rely on the dma-buf merge for vmap
  stuff, and I've a few fixes building up, but I'd decided I'd better
  get rid of the main pull sooner rather than later, so the audio guys
  are also unblocked."

Fix up trivial conflict due to some duplicated changes in
drivers/gpu/drm/i915/intel_ringbuffer.c
