Standard CONFIG_MAXSMP setting. I believe distros set that. At least
SLES on x86_64 does and I'd bet RHEL does that too.
config NR_CPUS
int "Maximum number of CPUs" if SMP && !MAXSMP
range 2 8 if SMP && X86_32 && !X86_BIGSMP
range 2 512 if SMP && !MAXSMP && !CPUMASK_OFFSTACK
range 2 8192 if SMP && !MAXSMP && CPUMASK_OFFSTACK && X86_64
default "1" if !SMP
default "8192" if MAXSMP
^^^^^^
