| 2055 | kexec is a system call that implements the ability to shutdown your |
| 2056 | current kernel, and to start another kernel. It is like a reboot |
| 2057 | but it is independent of the system firmware. And like a reboot |
| 2058 | you can start any kernel with it, not just Linux. |
| 2059 | |
| 2060 | The name comes from the similarity to the exec system call. |
| 2061 | |
| 2062 | It is an ongoing process to be certain the hardware in a machine |
| 2063 | is properly shutdown, so do not be surprised if this code does not |
| 2064 | initially work for you. It may help to enable device hotplugging |
| 2065 | support. As of this writing the exact hardware interface is |
