| kexec is a system call that implements the ability to shutdown your | |
| current kernel, and to start another kernel. It is like a reboot | |
| but it is independent of the system firmware. And like a reboot | |
| you can start any kernel with it, not just Linux. | |
| 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 | |
| support. As of this writing the exact hardware interface is | |
