162 | Enable this if you want to support 64bit kernel on PA-RISC platform. | |
163 | ||
164 | At the moment, only people willing to use more than 2GB of RAM, | |
165 | or having a 64bit-only capable PA-RISC machine should say Y here. | |
166 | ||
167 | Since there is no 64bit userland on PA-RISC, there is no point to | |
168 | enable this option otherwise. The 64bit kernel is significantly bigger | |

206 | This enables support for systems with more than one CPU. If you have | |

208 | you have a system with more than one CPU, say Y. | |

211 | machines, but will use only one CPU of a multiprocessor machine. If | |
212 | you say Y here, the kernel will run on many, but not all, | |
213 | singleprocessor machines. On a singleprocessor machine, the kernel | |
214 | will run faster if you say N here. | |
