  1. [git pull] drm radeon fix for 2.6.27-rc1


    Hi Linus,

    Please pull the 'drm-fixes' branch from
    ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-fixes

    It appears we have a PAT incomPATibility, with how the radeon driver was
    mapping some VRAM.

    Dave.

    drm/radeon: fixup issue with radeon and PAT support.

    With new userspace libpciaccess we can get a conflicting mapping
    on the PCIE GART table in the video RAM. Always try and map it _wc.
