  241. kexec is a system call that implements the ability to shutdown your
  242. current kernel, and to start another kernel. It is like a reboot
  243. but it is independent of the system firmware. And like a reboot
  244. you can start any kernel with it, not just Linux.
  245. The name comes from the similarity to the exec system call.
  246. It is an ongoing process to be certain the hardware in a machine
  247. is properly shutdown, so do not be surprised if this code does not
  248. initially work for you. It may help to enable device hotplugging
  249. support. As of this writing the exact hardware interface is
