+ 	help
+ 	  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.
