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