 183           At the moment, only people willing to use more than 2GB of RAM,
 184           or having a 64bit-only capable PA-RISC machine should say Y here.
 185
 186           Since there is no 64bit userland on PA-RISC, there is no point to
 187           enable this option otherwise. The 64bit kernel is significantly bigger

 225           This enables support for systems with more than one CPU. If you have

 227           you have a system with more than one CPU, say Y.
 228
 229           If you say N here, the kernel will run on single and multiprocessor
 230           machines, but will use only one CPU of a multiprocessor machine. If
 231           you say Y here, the kernel will run on many, but not all,
 232           singleprocessor machines. On a singleprocessor machine, the kernel
 233           will run faster if you say N here.
