 165           Enable this if you want to support 64bit kernel on PA-RISC platform.

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

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

 209           This enables support for systems with more than one CPU. If you have
 210           a system with only one CPU, like most personal computers, say N. If
 211           you have a system with more than one CPU, say Y.
 212
 213           If you say N here, the kernel will run on single and multiprocessor
 214           machines, but will use only one CPU of a multiprocessor machine. If
 215           you say Y here, the kernel will run on many, but not all,
 216           singleprocessor machines. On a singleprocessor machine, the kernel
 217           will run faster if you say N here.
