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

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

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