  83           used for optimizing purposes.  In order to compile a kernel
  84           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  85           you can specify "PA7000" here.

 136           Enable this if you want to support 64bit kernel on PA-RISC platform.
 137
 138           At the moment, only people willing to use more than 2GB of RAM,
 139           or having a 64bit-only capable PA-RISC machine should say Y here.
 140
 141           Since there is no 64bit userland on PA-RISC, there is no point to
 142           enable this option otherwise. The 64bit kernel is significantly bigger
 143           and slower than the 32bit one.

 179           This enables support for systems with more than one CPU. If you have
 180           a system with only one CPU, like most personal computers, say N. If
 181           you have a system with more than one CPU, say Y.
 182
 183           If you say N here, the kernel will run on single and multiprocessor
 184           machines, but will use only one CPU of a multiprocessor machine. If
 185           you say Y here, the kernel will run on many, but not all,
 186           singleprocessor machines. On a singleprocessor machine, the kernel
 187           will run faster if you say N here.
