  428. kexec is a system call that implements the ability to shutdown your
  429. current kernel, and to start another kernel. It is like a reboot
  430. but it is independent of the system firmware. And like a reboot
  431. you can start any kernel with it, not just Linux.
  432. The name comes from the similarity to the exec system call.
  433. It is an ongoing process to be certain the hardware in a machine
  434. is properly shutdown, so do not be surprised if this code does not
  435. initially work for you. It may help to enable device hotplugging
  436. support. As of this writing the exact hardware interface is
  437. strongly in flux, so no good recommendation can be made.

  443. you have a system with more than one CPU, say Y.

  445. machines, but will use only one CPU of a multiprocessor machine. If
