 569           kexec is a system call that implements the ability to shutdown your
 570           current kernel, and to start another kernel.  It is like a reboot
 571           but it is independent of the system firmware.  And like a reboot
 572           you can start any kernel with it, not just Linux.
 573
 574           The name comes from the similarity to the exec system call.
