sys/vm vm_map.c
Log:
Fix a bug which was introduced in version 1.187.2.16 of
sys/vm/vm_map.c and affects the unwiring memory:
The map entries are processed in a loop, checking to make sure the
entry is wired and asserting it has a wired count. However, another
loop was inserted more-or-less in the middle of the of the unwiring
path. This loop picks up the "entry" loop variable from the first loop
without first setting it to start_entry. Naturally, the second loop
is never entered and the pages backing the entries are never unwired.
This can lead to a leak of wired pages.
