          This allows you to specify the maximum number of CPUs which this
-         kernel will support.  The maximum supported value is 4096 and the

          minimum value which makes sense is 2.
 
          This is purely to save memory - each supported CPU adds
          approximately eight kilobytes to the kernel image.
