1657 | This allows you to specify the maximum number of CPUs which this | |
1658 | kernel will support. The maximum supported value is 32 for 32-bit | |
1659 | kernel and 64 for 64-bit kernels; the minimum value which makes | |

1661 | and 2 for all others. | |

1664 | approximately eight kilobytes to the kernel image. For best |

1755 | kexec is a system call that implements the ability to shutdown your | |
