I have queued up a subset of this series for next, for those changes I have replied separately. However to also simplify for people to test and to get some build reports from 0-build, I have published a cmdq branch in my mmc tree. The branch is not intended to stay that long-term, it is just as an intermediate step to help to find any further issues.
