Log Message:
pmap_remove_all(): Return a boolean value to indicate the behaviour.  If
true, all mappings have been removed, the pmap is totally cleared out, and
UVM can then avoid doing the work to call pmap_remove() for each map entry.
If false, either nothing has been done, or some helpful arch-specific voodoo
has taken place.
