  1551. This allows you to specify the maximum number of CPUs which this
  1552. kernel will support. The maximum supported value is 32 for 32-bit
  1553. kernel and 64 for 64-bit kernels; the minimum value which makes
  1554. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1555. and 2 for all others.
  1556. This is purely to save memory - each supported CPU adds
  1557. approximately eight kilobytes to the kernel image. For best
