Can you not line-wrap these sparse warning lines, it makes them hard to
read. It's ok to leave them as very long lines in the changelog.

This feels wrong, u64 should be used instead, can the code be fixed up
to use that type properly? Don't rely on long long anywhere, it's hard
to always know what it should be on all arches...
Please fix up and resend this series based on the reviews you've gotten
so far.
