13 | The PA-RISC microprocessor is designed by Hewlett-Packard and used | |
14 | in many of their workstations & servers (HP9000 700 and 800 series, | |
15 | and later HP3000 series). The PA-RISC Linux project home page is | |

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

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

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

206 | machines, but will use only one CPU of a multiprocessor machine. If | |
207 | you say Y here, the kernel will run on many, but not all, | |
208 | singleprocessor machines. On a singleprocessor machine, the kernel | |
209 | will run faster if you say N here. | |
