He means I apply them all at once as a single commit.  We had to do this
with the first five patches of Online Controller Reset which were
likewise unbisectable.   It's a way of getting around the mailing list
patch size limite (currently about $150k, I think) and making the
patches more reviewable.

What I do want for this is a rolled up change log for the entire commit,
please.
