1676 | This allows you to specify the maximum number of CPUs which this | |
1677 | kernel will support. The maximum supported value is 32 for 32-bit | |
1678 | kernel and 64 for 64-bit kernels; the minimum value which makes | |

1680 | and 2 for all others. | |

1774 | kexec is a system call that implements the ability to shutdown your | |
