Several of the patches don't really depend on (all) earlier ones. It is
in particular patch 12 which I'd really appreciate if it could go in rather
sooner than later, due to it otherwise being unduly cumbersome for
me to make further changes in this area (as was e.g. required for
https://lists.xenproject.org/archives/html/xen-devel/2016-09/msg01669.html,
and which is not all that unlikely to become necessary).

I'll also refrain from posting a v2 of the follow-up series until that one
did actually get looked at (or until a meaningful part of the series here
has gone in).

Thanks, Jan
