+         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.
