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

Pull drm main changes from Dave Airlie:
 "This is the main drm pull request, I'm probably going to send two more
  smaller ones, will explain below.

  This contains a patch that is also in the fbdev tree, but it should be
  the same patch, it added an API for hot unplugging framebuffer
  devices, and I need that API for a new driver.

  It also contains some changes to the i2c tree which Jean has acked,
  and one change to moorestown platform stuff in x86.

  Highlights:
   - new drivers: UDL driver for USB displaylink devices, kms only,
     should support correct hotplug operations.
   - core: i2c speedups + better hotplug support, EDID overriding via
     firmware interface - allows user to load a firmware for a broken
     monitor/kvm from userspace, it even has documentation for it.
   - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
   - gma500: code cleanup
   - radeon: cleanups, CS optimisations, streamout support and pageflip
     fix
   - nouveau: NVD9 displayport support + more reclocking work
   - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
     who knows), missed irq fixes, stencil tiling fixes, interlaced
     support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
     semaphore fixes

  As well as the usual bunch of cleanups and fixes all over the place.

  I've got two things I'd like to merge a bit later:

   a) AMD support for all their new radeonhd 7000 series GPU and APUs.
      AMD dropped this a bit late due to insane internal review
      processes, (please AMD just follow Intel and let open source guys
      ship stuff early) however I don't want to penalise people who own
      this hardware (since its been on sale for 3-4 months and GPU hw
      doesn't exactly have a lifetime in years) and consign them to
      using closed drivers for longer than necessary.  The changes are
      well contained and just plug into the driver new gpu functionality
      so they should be fairly regression proof.  I just want to give
      them a bit of a run on the hw AMD kindly sent me.

   b) drm prime/dma-buf interface code.  This is just infrastructure
      code to expose the dma-buf stuff to drm drivers and to userspace.
      I'm not planning on pushing any driver support in this cycle
      (except maybe exynos), but I'd like to get the infrastructure code
      in so for the next cycle I can start getting the driver support
      into the individual drivers.  We have started driver support for
      i915, nouveau and udl along with I think exynos and omap in
      staging.  However this code relies on the dma-buf tree being
      pulled into your tree first since it needs the latest interfaces
      from that tree.  I'll push to get that tree sent asap.

  (oh and any warnings you see in i915 are gcc's fault from what anyone
  can see)."

Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
msic_thermal_platform_data() thermal function being added next to the
tc35876x_platform_data() i2c device function..
