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

87 | This is the processor type of your CPU. This information is | |

141 | Enable this if you want to support 64bit kernel on PA-RISC platform. | |
142 | ||
143 | At the moment, only people willing to use more than 2GB of RAM, | |
144 | or having a 64bit-only capable PA-RISC machine should say Y here. | |
145 | ||
146 | Since there is no 64bit userland on PA-RISC, there is no point to | |
147 | enable this option otherwise. The 64bit kernel is significantly bigger | |
148 | and slower than the 32bit one. | |

183 | ---help--- | |
184 | This enables support for systems with more than one CPU. If you have | |
185 | a system with only one CPU, like most personal computers, say N. If | |
186 | you have a system with more than one CPU, say Y. | |
187 | ||
188 | If you say N here, the kernel will run on single and multiprocessor | |
189 | machines, but will use only one CPU of a multiprocessor machine. If | |
190 | you say Y here, the kernel will run on many, but not all, | |
191 | singleprocessor machines. On a singleprocessor machine, the kernel | |
192 | will run faster if you say N here. | |
