This assumes PR KVM won't ever support TM, which is hopefully not true. If PR KVM does get TM support in future, then QEMU will have no clear way to know whether it needs to clear the pa-features bit or not. I think we need to define some way for the KVM implementation to tell qemu which of these kinds of CPU features it supports. However, we could defer implementing that mechanism until PR KVM does get support for TM, I guess. In that case this patch could go in now, though it seems slightly icky to be using the pvinfo stuff to distinguish PR from HV.
