458 | kexec is a system call that implements the ability to shutdown your |
459 | current kernel, and to start another kernel. It is like a reboot | |
460 | but it is indepedent of the system firmware. And like a reboot | |
461 | you can start any kernel with it, not just Linux. | |
462 | ||
463 | The name comes from the similiarity to the exec system call. | |
464 | ||
465 | It is an ongoing process to be certain the hardware in a machine | |
466 | is properly shutdown, so do not be surprised if this code does not | |
467 | initially work for you. It may help to enable device hotplugging | |
468 | support. As of this writing the exact hardware interface is | |
469 | strongly in flux, so no good recommendation can be made. | |

477 | ---help--- | |
478 | This enables support for systems with more than one CPU. If you have | |
479 | a system with only one CPU, like most personal computers, say N. If | |
480 | you have a system with more than one CPU, say Y. | |
481 | ||
482 | If you say N here, the kernel will run on single and multiprocessor | |
483 | machines, but will use only one CPU of a multiprocessor machine. If | |
484 | you say Y here, the kernel will run on many, but not all, | |
485 | singleprocessor machines. On a singleprocessor machine, the kernel | |
486 | will run faster if you say N here. | |
