This (and patch 13/13) depend on another series that I had expected to
go into Tom's tree earlier than this series. However, there were some
unexpected regressions caused by the other series, so I've got a couple
of minor changes to that, so maybe I should just add these two patches
to the other series for Tom to pick up?
