KVM: PPC: bookehv: add comment about shadow_msr
For BookE HV the guest visible MSR is shared->msr and is identical to the MSR that is in use while the guest is running, because we can't trap reads from/to MSR. So shadow_msr is unused there. Indicate that with a comment. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
