FYI, my compile testing was very basic and a few issues showed up
from the build bot later on. I'll keep the branch here uptodate
for now:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/generic-gup
and won't resend until we make progress on the pointer tagging
thing. I've also got a few follow on patches on top, so they might
be ready by then as well.
