Any objections to this one? I just rebased this one and the full arch
series that sits on top for -git, but apart from that, no changes.

Thomas, would be nice to know if you're good with patch 2+3 at this
point. Once we get outside of the merge window next week, I'll post
the updated series since we get a few conflicts at this point, and
would be great if you could carry this for 5.11.
