pmap_collect() and PG_UNMANAGED

2001-10-31 Thread 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
