config KEXEC

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

	  current kernel, and to start another kernel.  It is like a reboot

	  but it is indepedent of the system firmware.   And like a reboot

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



	  The name comes from the similiarity to the exec system call.



	  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.
