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: (133 commits)
drm/vgaarb: add VGA arbitration support to the drm and kms.
drm/radeon: some r420s have a CP race with the DMA engine.
drm/radeon/r600/kms: rv670 is not DCE3
drm/radeon/kms: r420 idle after programming GA_ENHANCE
drm/radeon/kms: more fixes to rv770 suspend/resume path.
drm/radeon/kms: more alignment for rv770.c with r600.c
drm/radeon/kms: rv770 blit init called too late.
drm/radeon/kms: move around new init path code to avoid posting at init
drm/radeon/r600: fix some issues with suspend/resume.
drm/radeon/kms: disable VGA rendering engine before taking over VRAM
drm/radeon/kms: Move radeon_get_clock_info() call out of radeon_clocks_init().
drm/radeon/kms: add initial connector properties
drm/radeon/kms: Use surfaces for scanout / cursor byte swapping on big endian.
drm/radeon/kms: don't fail if we fail to init GPU acceleration
drm/r600/kms: fixup number of loops per blit calculation.
drm/radeon/kms: reprogram format in set base.
drm/radeon: avivo chips have no separate int bit for display
drm/radeon/r600: don't do interrupts
drm: fix _DRM_GEM addmap error message
drm: update crtc x/y when only fb changes
...
Fixed up trivial conflicts in firmware/Makefile due to network driver
(cxgb3) and drm (mga/r128/radeon) firmware being listed next to each
other.
