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

176 | At the moment, only people willing to use more than 2GB of RAM, | |
177 | or having a 64bit-only capable PA-RISC machine should say Y here. | |

179 | Since there is no 64bit userland on PA-RISC, there is no point to | |
180 | enable this option otherwise. The 64bit kernel is significantly bigger | |

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

224 | you say Y here, the kernel will run on many, but not all, | |
225 | singleprocessor machines. On a singleprocessor machine, the kernel | |
226 | will run faster if you say N here. | |
