  1536. This allows you to specify the maximum number of CPUs which this
  1537. kernel will support. The maximum supported value is 32 for 32-bit
  1538. kernel and 64 for 64-bit kernels; the minimum value which makes
  1539. sense is 2.
  1540. This is purely to save memory - each supported CPU adds
  1541. approximately eight kilobytes to the kernel image.

  1611. kexec is a system call that implements the ability to shutdown your

  1614. you can start any kernel with it, not just Linux.
