 162           At the moment, only people willing to use more than 2GB of RAM,
 163           or having a 64bit-only capable PA-RISC machine should say Y here.
 164
 165           Since there is no 64bit userland on PA-RISC, there is no point to
 166           enable this option otherwise. The 64bit kernel is significantly bigger
 167           and slower than the 32bit one.

 180           compatibility with 32bit applications, a page size of 4KB should be

 204           This enables support for systems with more than one CPU. If you have
 205           a system with only one CPU, like most personal computers, say N. If
 206           you have a system with more than one CPU, say Y.
 207
 208           If you say N here, the kernel will run on single and multiprocessor
 209           machines, but will use only one CPU of a multiprocessor machine. If
 210           you say Y here, the kernel will run on many, but not all,
 211           singleprocessor machines. On a singleprocessor machine, the kernel
 212           will run faster if you say N here.
