You mean even kvm.ko doesn't use privileged instructions?
It does, but I don't think it's worth speeding those up. There are only a couple. Most of the privileged instructions in PPC KVM are statically compiled into the kernel because we need to guarantee they're in the RMO (first 8MB for the PS3).
Even with the magic page in use, trapping instructions still works exactly as before, so we're only talking about a speed difference.
Yeah, that also answers my question re pv->nonpv transition.
