KVM: ppc: split out common Book E instruction emulation The Book E code will be shared with e500. I've left PID in kvmppc_core_emulate_op() just so that we don't need to move kvmppc_set_pid() right now. Once we have the e500 implementation, we can probably share that too.

KVM: PPC: Convert MSR to shared page One of the most obvious registers to share with the guest directly is the MSR. The MSR contains the "interrupts enabled" flag which the guest has to toggle in critical sections. So in order to bring the overhead of interrupt en- and disabling down, let's put msr into the shared page. Keep in mind that even though you can fully read its contents, writing to it doesn't always update all state. There are a few safe fields that don't require hypervisor interaction. See the documentation for a list of MSR bits that are safe to be set from inside the guest. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
