description:
Pull up revision 1.21 (requested by sommerfeld in ticket #406):
Since the KERN_CP_TIME sysctl reports total clock ticks across all
cpus and hz is measured in ticks per cpu, divide tick count by ncpu to
determine elapsed time since last sample.
Fixes I/O rate deflation observed on multiprocessors.
