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

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

176 | Since there is no 64bit userland on PA-RISC, there is no point to | |
