  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
  1560. performance should round up your number of processors to the next
  1561. power of two.

  1629. kexec is a system call that implements the ability to shutdown your
