Most of my patch series can be upstreamed right now, the only thing that
needs some extra work is the pirq remapping.
So yes, we can upstream the rest and that would also make PV on HVM work
on linux upstream ASAP.
I think that is a worthy goal by itself, therefore I am going to send
another reduced patch series, ready to be upstreamed, without pirq
remappings, with support for PV on HVM.
