13 | and later HP3000 series). The PA-RISC Linux project home page is | |

154 | help | |
155 | Enable this if you want to support 64bit kernel on PA-RISC platform. | |
156 | ||
157 | At the moment, only people willing to use more than 2GB of RAM, | |
158 | or having a 64bit-only capable PA-RISC machine should say Y here. | |
159 | ||
160 | Since there is no 64bit userland on PA-RISC, there is no point to | |
161 | enable this option otherwise. The 64bit kernel is significantly bigger | |
162 | and slower than the 32bit one. | |

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

200 | you have a system with more than one CPU, say Y. | |
201 | ||
202 | If you say N here, the kernel will run on single and multiprocessor | |
203 | machines, but will use only one CPU of a multiprocessor machine. If | |
204 | you say Y here, the kernel will run on many, but not all, | |
205 | singleprocessor machines. On a singleprocessor machine, the kernel | |
206 | will run faster if you say N here. | |
