  1571. This allows you to specify the maximum number of CPUs which this
  1572. kernel will support. The maximum supported value is 32 for 32-bit
  1573. kernel and 64 for 64-bit kernels; the minimum value which makes
  1574. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1575. and 2 for all others.
  1576. This is purely to save memory - each supported CPU adds

  1647. kexec is a system call that implements the ability to shutdown your
