 171           Enable this if you want to support 64bit kernel on PA-RISC platform.
 172
 173           At the moment, only people willing to use more than 2GB of RAM,
 174           or having a 64bit-only capable PA-RISC machine should say Y here.
 175
 176           Since there is no 64bit userland on PA-RISC, there is no point to
 177           enable this option otherwise. The 64bit kernel is significantly bigger
 178           and slower than the 32bit one.

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

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