? % grep MAXCPU ~/work/freebsd/svn/head/sys/amd64/include/param.h #define MAXCPU 32 #define MAXCPU 1 In fact: % grep MAXCPU ~/work/freebsd/svn/stable/8/sys/amd64/include/param.h #define MAXCPU 32 #define MAXCPU 1 Unfortunately this can't be MFC'd to 7 as it would destroy the ABI for existing klds. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
