  Please could you pick up my patch in bug 606081

It fixes a missing copy_from_user in the radeon drm code that
causes an oops running google earth on 64bit Maverick.

It's not clear to me whether there also needs to be a separate
fix to the 32bit compat code; but the patch fixes the oops
which is a pretty obvious missing copy_from_user.
(I don't think it's actually a security issue - the read value
is only used in a comparison, not returned directly).
