What's the plan here? While not a requirement for merging, that's

I'm having a deja vu :-).
Will probably get one on every repost.
The plan is to get qemu ppc64 guest support in a shape where it can
actually use the KVM support. As it is it's rather useless.
When we have that, a PV interface would be needed to get things fast
and then the next thing on my list is the MMU notifiers.
Um. How slow is it today? What paths are problematic? mmu, context switch?
Our experience with pv on x86 has been mostly negative. It's not
trivial to get security right, it ended up slower than non-pv, and
hardware obsoleted it fairly quickly.
