Hi; I've reviewed some of the simpler parts of this, but I
suspect I'm not going to get to the rest of it for a bit (the
softfreeze deadline is next Tuesday, so it's a busy time of
the release cycle for me). For the moment I'm going to take
patches 4, 5 and 12 into target-arm.next, which should at least
reduce the size of the patchset for next time.
