	  kexec is a system call that implements the ability to shutdown your
	  current kernel, and to start another kernel.  It is like a reboot
626
	  but it is independent of the system firmware.  And like a reboot
627 628
	  you can start any kernel with it, not just Linux.

629
	  The name comes from the similarity to the exec system call.
630 631 632 633 634 635 636

	  It is an ongoing process to be certain the hardware in a machine
	  is properly shutdown, so do not be surprised if this code does not
	  initially work for you.  It may help to enable device hotplugging
	  support.  As of this writing the exact hardware interface is
	  strongly in flux, so no good recommendation can be made.
