552	  kexec is a system call that implements the ability to shutdown your
553	  current kernel, and to start another kernel.  It is like a reboot
554	  but it is independent of the system firmware.  And like a reboot
555	  you can start any kernel with it, not just Linux.
556
557	  The name comes from the similarity to the exec system call.
558
559	  It is an ongoing process to be certain the hardware in a machine
560	  is properly shutdown, so do not be surprised if this code does not
561	  initially work for you.  As of this writing the exact hardware

601	  This enables support for systems with more than one CPU. If you have
602	  a system with only one CPU, say N. If you have a system with more
603	  than one CPU, say Y.
604
605	  If you say N here, the kernel will run on uni- and multiprocessor
606	  machines, but will use only one CPU of a multiprocessor machine. If
607	  you say Y here, the kernel will run on many, but not all,
608	  uniprocessor machines. On a uniprocessor machine, the kernel
609	  will run faster if you say N here.
610
611	  People using multiprocessor machines who say Y here should also say
612	  Y to "Enhanced Real Time Clock Support", below.
