  88           used for optimizing purposes.  In order to compile a kernel
  89           that can run on all 32-bit PA CPUs (albeit not optimally fast),

 141           Enable this if you want to support 64bit kernel on PA-RISC platform.
 142
 143           At the moment, only people willing to use more than 2GB of RAM,
 144           or having a 64bit-only capable PA-RISC machine should say Y here.
 145
 146           Since there is no 64bit userland on PA-RISC, there is no point to
 147           enable this option otherwise. The 64bit kernel is significantly bigger
 148           and slower than the 32bit one.

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