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

Pull drm updates from Dave Airlie:
 "Been a bit busy, first week of kids school, and waiting on other trees
  to go in before I could send this, so its a bit later than I'd
  normally like.

  Highlights:
   - core:
      timestamp fixes, lots of misc cleanups
   - new drivers:
      bochs virtual vga
   - vmwgfx:
      major overhaul for their nextgen virt gpu.
   - i915:
      runtime D3 on HSW, watermark fixes, power well work, fbc fixes,
      bdw is no longer prelim.
   - nouveau:
      gk110/208 acceleration, more pm groundwork, old overlay support
   - radeon:
      dpm rework and clockgating for CIK, pci config reset, big endian
      fixes
   - tegra:
      panel support and DSI support, build as module, prime.
   - armada, omap, gma500, rcar, exynos, mgag200, cirrus, ast:
      fixes
   - msm:
      hdmi support for mdp5"
