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

Pull drm merge from Dave Airlie:
 "Highlights:

   - TI LCD controller KMS driver

   - TI OMAP KMS driver merged from staging

   - drop gma500 stub driver

   - the fbcon locking fixes

   - the vgacon dirty like zebra fix.

   - open firmware videomode and hdmi common code helpers

   - major locking rework for kms object handling - pageflip/cursor
     won't block on polling anymore!

   - fbcon helper and prime helper cleanups

   - i915: all over the map, haswell power well enhancements, valleyview
     macro horrors cleaned up, killing lots of legacy GTT code,

   - radeon: CS ioctl unification, deprecated UMS support, gpu reset
     rework, VM fixes

   - nouveau: reworked thermal code, external dp/tmds encoder support
     (anx9805), fences sleep instead of polling,

   - exynos: all over the driver fixes."

Lovely conflict in radeon/evergreen_cs.c between commit de0babd6
("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd")
and the new changes that modified that evergreen_dma_cs_parse()
function.

        Beside some lookup structures with their own locking (which is hidden

	behind the interface functions) most of the modeset state is protected

	by the <code>dev-&lt;mode_config.lock</code> mutex and additionally

	per-crtc locks to allow cursor updates, pageflips and similar operations

	to occur concurrently with background tasks like output detection.

	Operations which cross domains like a full modeset always grab all

	locks. Drivers there need to protect resources shared between crtcs with

	additional locking. They also need to be careful to always grab the

	relevant crtc locks if a modset functions touches crtc state, e.g. for

	load detection (which does only grab the <code>mode_config.lock</code>

	to allow concurrent screen updates on live crtcs).
