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