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