  1553. This allows you to specify the maximum number of CPUs which this
  1554. kernel will support. The maximum supported value is 32 for 32-bit
  1555. kernel and 64 for 64-bit kernels; the minimum value which makes
  1556. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1557. and 2 for all others.
  1558. This is purely to save memory - each supported CPU adds
  1559. approximately eight kilobytes to the kernel image. For best
