 103           kexec is a system call that implements the ability to shutdown your
 104           current kernel, and to start another kernel.  It is like a reboot
 105           but it is independent of the system firmware.   And like a reboot
 106           you can start any kernel with it, not just Linux.
 107
 108           The name comes from the similarity to the exec system call.
 109
 110           It is an ongoing process to be certain the hardware in a machine
 111           is properly shutdown, so do not be surprised if this code does not
 112           initially work for you.  As of this writing the exact hardware
 113           interface is strongly in flux, so no good recommendation can be
 114           made.
