  1576. kernel will support. The maximum supported value is 32 for 32-bit
  1577. kernel and 64 for 64-bit kernels; the minimum value which makes
  1578. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1579. and 2 for all others.
  1580. This is purely to save memory - each supported CPU adds
  1581. approximately eight kilobytes to the kernel image. For best
