 164           Enable this if you want to support 64bit kernel on PA-RISC platform.
 165
 166           At the moment, only people willing to use more than 2GB of RAM,
 167           or having a 64bit-only capable PA-RISC machine should say Y here.
 168
 169           Since there is no 64bit userland on PA-RISC, there is no point to
 170           enable this option otherwise. The 64bit kernel is significantly bigger
 171           and slower than the 32bit one.

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

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