Pull drm fixes from Dave Airlie: "Daniel had some fixes queued up, that were delayed, the stolen memory ones and vga arbiter ones are quite useful, along with his usual bunch of stuff, nothing for HSW outputs yet. The one nouveau fix is for a regression I caused with the poweroff stuff" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits) drm/nouveau: fix oops on runtime suspend/resume drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is done drm/i915: try not to lose backlight CBLV precision drm/i915: Confine page flips to BCS on Valleyview drm/i915: Skip stolen region initialisation if none is reserved drm/i915: fix gpu hang vs. flip stall deadlocks drm/i915: Hold an object reference whilst we shrink it drm/i915: fix i9xx_crtc_clock_get for multiplied pixels drm/i915: handle sdvo input pixel multiplier correctly again drm/i915: fix hpd work vs. flush_work in the pageflip code deadlock drm/i915: fix up the relocate_entry refactoring drm/i915: Fix pipe config warnings when dealing with LVDS fixed mode drm/i915: Don't call sg_free_table() if sg_alloc_table() fails i915: Update VGA arbiter support for newer devices vgaarb: Fix VGA decodes changes vgaarb: Don't disable resources that are not owned drm/i915: Pin pages whilst mapping the dma-buf drm/i915: enable trickle feed on Haswell x86: add early quirk for reserving Intel graphics stolen memory v5 drm/i915: split PCI IDs out into i915_drm.h v4 ... |

************************************************************
The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
http://dri.freedesktop.org/wiki/Documentation

http://dri.sourceforge.net/doc/
