Merge branch 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6

* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (22 commits) drm: add initial r500 drm support radeon: setup the ring buffer fetcher to be less agressive. drm: fixup some of the ioctl function exit paths drm: the drm really should call pci_set_master.. i915: Add chipset id for Intel Integrated Graphics Device drm: cleanup DRM_DEBUG() parameters drm/i915: add support for E7221 chipset drm: don't cast a pointer to pointer of list_head mga_dma: return 'err' not just zero from mga_do_cleanup_dma() drm: add _DRM_DRIVER flag, and re-order unload. drm: enable udev node creation drm: Make DRM_IOCTL_GET_CLIENT return EINVAL when it can't find client #idx. drm: move drm_mem_init to proper place in startup sequence drm: call driver load function after initialising AGP drm: Fix ioc32 compat layer drm: fd.o bug #11895: Only add the AGP base to map offset if the caller didn't. i915: add suspend/resume support drm: update DRM sysfs support drm: Initialize the AGP structure's base address at init rather than enable. drm: move two function extern into the correct block ...
