Merge branch 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6
* 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: drm/radeon/kms: Fix oops after radeon_cs_parser_init() failure. drm/radeon/kms: move radeon KMS on/off switch out of staging. drm/radeon/kms: Bailout of blit if error happen & protect with mutex V3 drm/vmwgfx: Don't send bad flags to the host drm/vmwgfx: Request SVGA version 2 and bail if not found drm/vmwgfx: Correctly detect 3D drm/ttm: remove unnecessary save_flags and ttm_flag_masked in ttm_bo_util.c drm/kms: Remove incorrect comment in struct drm_mode_modeinfo drm/ttm: remove padding from ttm_ref_object on 64bit builds drm/radeon/kms: release agp on error. drm/kms/radeon/agp: Move the check of the aper_size after drm_acp_acquire and drm_agp_info drm/kms/radeon/agp: Fix warning, format ‘%d’ expects type ‘int’, but argument 4 has type ‘size_t’ drm/ttm: Avoid conflicting reserve_memtype during ttm_tt_set_page_caching. drm/kms/radeon: pick digitial encoders smarter. (v3) drm/radeon/kms: use active device to pick connector for encoder drm/radeon/kms: fix incorrect logic in DP vs eDP connector checking.
