Change 131650 by jb at jb_freebsd1 on 2007/12/26 06:19:53

	Size the global CPU array using SMP_MAXCPU to allow for the maximum
	number of CPUs that the kernel would support if configured with SMP
	enabled.
	
	When looping through CPU IDs, use the mp_maxid variable as the limit
	for the maximum ID to look for.
