  1560. This allows you to specify the maximum number of CPUs which this
  1561. kernel will support. The maximum supported value is 32 for 32-bit
  1562. kernel and 64 for 64-bit kernels; the minimum value which makes
  1563. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1564. and 2 for all others.
  1565. This is purely to save memory - each supported CPU adds
  1566. approximately eight kilobytes to the kernel image. For best
