[git pull] drm fixes tree

[Dave Airlie <airlied@linux.ie>]

Hi Linus/Andrew,

	Can you pull the 'drm-linus' branch from

rsync://rsync.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git

It contains three minor fixes as shown below...

Dave.

    drm: move is_pci to the end of the structure

    We memset the structure across opens except for the flags. The correct
    fix is more intrusive but this should fix a problem with bad iounmaps
    seen on AGP radeons acting like PCI ones.

    drm: add __GFP_COMP to the drm_alloc_pages

    The DRM only uses drm_alloc_pages for non-SG PCI cards using DRM.

commit bd07ed2b4d7071716c09895e19849e8b04991656

    I think that if a PCI bus is a root bus, attached to a host bridge not a
    PCI->PCI bridge, then bus->self is allowed to be NULL. Certainly that's
    the case on my Pegasos, and it makes the MGA DRM driver oops...
