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

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

204 | machines, but will use only one CPU of a multiprocessor machine. If | |
