1664 | This allows you to specify the maximum number of CPUs which this | |
1665 | kernel will support. The maximum supported value is 32 for 32-bit | |
1666 | kernel and 64 for 64-bit kernels; the minimum value which makes | |
72ede9b1 AN |
1667 | sense is 1 for Qemu (useful only for kernel debugging purposes) |
1668 | and 2 for all others. | |

1671 | approximately eight kilobytes to the kernel image. For best |
1672 | performance should round up your number of processors to the next | |

1762 | kexec is a system call that implements the ability to shutdown your | |
