Subject: [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.

Hi David,

it affects stable (2.6.26) too?
