KVM: PPC: Book3S: PR: Enable interrupts earlier
Now that the svcpu sync is interrupt aware we can enable interrupts earlier in the exit code path again, moving 32bit and 64bit closer together. While at it, document the fact that we're always executing the exit path with interrupts enabled so that the next person doesn't trap over this. Signed-off-by: Alexander Graf <agraf@suse.de>
