May I repeat my request for comments, suggestions, wishes regarding this
series? If there are concerns, even vague ones, please let us discuss
them. I think the last one raised by Paul should be solved by the
update I sent. If you don't think so, share your concerns.

If there are no more concern, then it would be nice to merge the series
and test things further this way. You can be sure I won't run away once
all bits are in, I'm most interested in a stable and clean solution.

See, we (CT as well as our customer) would be more happy to spend the
currently available resources on improving the patches than on
maintaining them out of tree (specifically as we need them in KVM as well).

Thanks,
Jan
