[PATCH 3/8] KVM: PPC: Book3S HV: Speed up wakeups of CPUs on HV KVM

From: Benjamin Herrenschmidt Currently, we wake up a CPU by sending a host IPI with smp_send_reschedule() to thread 0 of that core, which will take all threads out of the guest, and cause them to re-evaluate their interrupt status on the way back in. This adds a mechanism to differentiate real h
