This should also save > one pagetable per process. Does this prevent us from using any memory in the user process above the 32-bit boundary? Or can it still be mapped/allocated with the stack region just treated as "already allocated"?

Precluding this would be somewhat of a lose. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
