1662 | This allows you to specify the maximum number of CPUs which this | |
1663 | kernel will support. The maximum supported value is 32 for 32-bit | |
1664 | kernel and 64 for 64-bit kernels; the minimum value which makes | |
72ede9b1 AN |
1665 | sense is 1 for Qemu (useful only for kernel debugging purposes) |
1666 | and 2 for all others. | |

1668 | This is purely to save memory - each supported CPU adds | |
72ede9b1 AN |
1669 | approximately eight kilobytes to the kernel image. For best |
1670 | performance should round up your number of processors to the next | |
1671 | power of two. | |

1759 | help | |
1760 | kexec is a system call that implements the ability to shutdown your | |
1761 | current kernel, and to start another kernel. It is like a reboot | |
3dde6ad8 | 1762 | but it is independent of the system firmware. And like a reboot |
ea6e942b AN |
1763 | you can start any kernel with it, not just Linux. |
