The pmap spinlocks are unnecessary, because the translator takes
shared/exclusive locks around all pmap operations. That should make any further
lower level locking an unnecessary overhead. If it judges shared vs exclusive
incorrectly, that's a separate problem.
If you can justify the locks by more detailed argument, please go ahead.
