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

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

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