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

653 654
	  you can start any kernel with it, not just Linux.

655

	  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

	  support.  As of this writing the exact hardware interface is
	  strongly in flux, so no good recommendation can be made.
