612 | kexec is a system call that implements the ability to shutdown your | |

614 | but it is independent of the system firmware. And like a reboot | |
615 | you can start any kernel with it, not just Linux. | |
616 | ||

620 | is properly shutdown, so do not be surprised if this code does not | |
