        src/sys/arch/hp300/hp300: pmap.c
Log Message:
Make pmap_collect() actually do something useful.  If called with a user
pmap, forget all of the mappings for the user address space for that pmap.
This causes the PT pages to be freed so that they can be reclaimed by the
VM system. [*]

[*] Actually, in the current implementation, it merely causes the wiring
count on the PT pages to drop to 0, which allows them to be reclaimed by
the pagedaemon.  Handling of PT pages needs to be completely rewritten.
