Pull Exynos DRM changes from Dave Airlie: "So I totally missed Inki's pull request for -next, its fully exynos self contained." (I took just the actual commits, not Dave's two extraneous merges) * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (30 commits) drm/exynos: fixed exception to page allocation failure drm/exynos: use __free_page() to deallocate memory drm/exynos: fixed a comment to gem size. drm/exynos: removed unnecessary variable drm/exynos: do not release memory region from exporter. drm/exynos: set buffer type from exporter. drm/exynos: use alloc_page() to allocate pages. drm/exynos: fixed build warning. drm/exynos: fixed edid data setting at vidi connection request drm/exynos: check if raw edid data is fake or not for test drm/exynos: set edid fake data only for test. drm/exynos: removed unnecessary declaration. drm/exynos: fix buffer pitch calculation drm/exynos: check for null in return value of dma_buf_map_attachment() drm/exynos: return NULL if exynos_pages_to_sg fails drm/exynos: Use devm_* functions in exynos_mixer.c drm/exynos: Use devm_* functions in exynos_hdmi.c drm/exynos: Use devm_* functions in exynos_drm_fimd.c drm/exynos: Add missing static storage class specifier drm/exynos: add property for crtc mode ... |

************************************************************
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://sourceforge.net/project/showfiles.php?group_id=387
http://dri.sourceforge.net/doc/
