1668 | This allows you to specify the maximum number of CPUs which this | |
1669 | kernel will support. The maximum supported value is 32 for 32-bit | |
1670 | kernel and 64 for 64-bit kernels; the minimum value which makes | |

1671 | sense is 1 for Qemu (useful only for kernel debugging purposes) |
1672 | and 2 for all others. | |

1675 | approximately eight kilobytes to the kernel image. For best |

1766 | kexec is a system call that implements the ability to shutdown your | |
