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

| The name comes from the similarity to the exec system call. | |
| It is an ongoing process to be certain the hardware in a machine | |
| is properly shutdown, so do not be surprised if this code does not | |
| initially work for you. It may help to enable device hotplugging | |
