That would be great, thanks! And I understand, aren't we all busy? :)

I have resent as v4 just to ensure it's clear that these patches are not
yet applied. My e-mail [0] might have suggested the opposite, due to my
total noobness in using the b4 auto-thankanator, sorry if that was the
case.

Having patch 1 reviewed is the most important thing here. Other patches are
already reviewed by Maxime, so your review would of course be very useful
but not strictly necessary for this series to go forward.
