This exports the kernel cp_time array in exactly the form that systat
consumes it: an array of size CPUSTATES. My endeavour was not to produce
a superior MIB for managing the kernel, rather, to translate existing
kmem-accessed data into systl-access data. If there is a better format
via which this could be exported, we should probably make those
improvements prior to 5.0-RELEASE and without MFC'ing these changes so we
don't get any software using the current MIB that has to be changed. I
probably don't have time to contribute to such an effort and selected the
current path as the path of least resistance to removing the setgid bit
from systat and other current-day system monitoring software.
