Pull drm updates from Dave Airlie:
"Been a bit busy, first week of kids school, and waiting on other trees

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"
