Alexander Graf 5c6cedf488 KVM: PPC: Add PV guest critical sections ... When running in hooked code we need a way to disable interrupts without clobbering any interrupts or exiting out to the hypervisor. To achieve this, we have an additional critical field in the shared page. If that field is equal to the r1 register of the guest, it tells the hypervisor that we're in such a critical section and thus may not receive any interrupts.
