I suppose it could be statically initialized to 1 and moved, but in that case it needs renaming, as mp_ncpus implies SMP (mp_ prefix). If you want to make it ncpus and move it to sys/systm.h and stick it somewhere MI initialized to 1 that is fine. Then hw.ncpus can reference that (well, it's called hw.ncpu right now, perhaps it should be renamed to match the variable *shrug*) and kern.smp.cpus can die as it won't be needed any longer. > -Alfred -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
