241 | all sorts of stuff like CONFIG_MEMORY_START because the config | |

473 | behavior is platform-dependent, but normally the flash frequency is | |
474 | a hyperbolic function of the 5-minute load average. | |

493 | kexec is a system call that implements the ability to shutdown your |
494 | current kernel, and to start another kernel. It is like a reboot | |
1f1332f7 | 495 | but it is independent of the system firmware. And like a reboot |
cad82448 PM |
496 | you can start any kernel with it, not just Linux. |
497 | ||
1f1332f7 | 498 | The name comes from the similarity to the exec system call. |

500 | It is an ongoing process to be certain the hardware in a machine | |
501 | is properly shutdown, so do not be surprised if this code does not | |
502 | initially work for you. It may help to enable device hotplugging | |
503 | support. As of this writing the exact hardware interface is | |
504 | strongly in flux, so no good recommendation can be made. | |

508 | ---help--- | |
509 | This enables support for systems with more than one CPU. If you have | |

511 | you have a system with more than one CPU, say Y. | |
512 | ||
513 | If you say N here, the kernel will run on single and multiprocessor | |
514 | machines, but will use only one CPU of a multiprocessor machine. If | |
515 | you say Y here, the kernel will run on many, but not all, | |
516 | singleprocessor machines. On a singleprocessor machine, the kernel | |
517 | will run faster if you say N here. | |
