 168           Enable this if you want to support 64bit kernel on PA-RISC platform.

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

 184           This lets you select the page size of the kernel.  For best

 186           compatibility with 32bit applications, a page size of 4KB should be
 187           selected (the vast majority of 32bit binaries work perfectly fine

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