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

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

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