Sorry, I didn't comment on this series because the concept seemed
uncontroversial to me: you are trying to extend the virtualization
interface to follow hardware constraints and fix bugs.

PeterZ acked the most critical bits (smp.c) and most of the changes
are on the virtualization side.

So it's fine to me in principle, but I have not looked into finer
details. Can take it into one of the -tip trees if Linus doesn't
pull it for v4.8.

Thanks,
