 166           Enable this if you want to support 64bit kernel on PA-RISC platform.
 167
 168           At the moment, only people willing to use more than 2GB of RAM,
 169           or having a 64bit-only capable PA-RISC machine should say Y here.
 170
 171           Since there is no 64bit userland on PA-RISC, there is no point to
 172           enable this option otherwise. The 64bit kernel is significantly bigger
 173           and slower than the 32bit one.

 182           This lets you select the page size of the kernel.  For best
 183           performance, a page size of 16KB is recommended.  For best
 184           compatibility with 32bit applications, a page size of 4KB should be
 185           selected (the vast majority of 32bit binaries work perfectly fine

 190           64KB               For best performance, might give more overhead.

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