If your i386 system has panic()ed in pmap_remove_all() recently, I would
encourage you to update your pmap.c.

Modified files:
sys/i386/i386 pmap.c
Log:
Acquire the page queues lock in pmap_insert_entry(). (I used to believe
that the page's busy flag could be relied upon to synchronize access to the
pv list. I don't any longer. See, for example, the call to
pmap_insert_entry() from pmap_copy().)
