No, I don't provide stubs in the prep patch, and that has been intentional
as I don't want this to spread much. test_bitmap would be the only place
where they are somewht useful, and I just hope this test is eventually
getting rewritten to run in a normal user space context where the
uaccess tests can be resurrected.
