Does it work if you just add the check=20 for pmap=3D=3D0 to the old code, i.e. still use pmap_install and tpa to g= et=20 the mapping? --=20 Doug Rabson=09=09=09=09Mail: dfr@nlsystems.com =09=09=09=09=09Phone: +44 20 8348 6160 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ia64" in the body of the message
