SubjectRe: get_user_pages() still broken in 2.6

I don't understand the difference. I thought a locked page is one that
stays in memory (i.e. isn't swapped out) and whose physical address
never changes. Is that wrong? All I need to do is keep a page in
memory at the same physical address until I'm done with it.
