This is really just copying the logic from kvm_resched() from virt/kvm/kvm_main.c. And I'd prefer not to diverge from that. I do agree that there's a good chance we don't need it, as it seems to predate preempt notifiers: https://git.kernel.org/cgit/virt/kvm/kvm.git/commit/?id=3fca03653010b8c5fa63b99fc94c78cbfb433d00 But this is a discussion that should occur on the non-ppc specific code first :).
