pmap_collect() and PG_UNMANAGED

[David Xu]

Hi,   is there any reason why pmap_collect() in /sys/i386/i386/pmap.c does not   check PG_UNMANAGED flag? unmanaged page does not have pv_entry associated,   so call pmap_remove_all() has side effect, PG_MAPPED and PG_WRITEABLE are   roughly cleared. -- David Xu
