 171           At the moment, only people willing to use more than 2GB of RAM,
 172           or having a 64bit-only capable PA-RISC machine should say Y here.
 173
 174           Since there is no 64bit userland on PA-RISC, there is no point to
 175           enable this option otherwise. The 64bit kernel is significantly bigger

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