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

 150           Enable this if you want to support 64bit kernel on PA-RISC platform.
 151
 152           At the moment, only people willing to use more than 2GB of RAM,
 153           or having a 64bit-only capable PA-RISC machine should say Y here.
 154
 155           Since there is no 64bit userland on PA-RISC, there is no point to
 156           enable this option otherwise. The 64bit kernel is significantly bigger
 157           and slower than the 32bit one.

 170           compatibility with 32bit applications, a page size of 4KB should be

 193           This enables support for systems with more than one CPU. If you have
 194           a system with only one CPU, like most personal computers, say N. If
 195           you have a system with more than one CPU, say Y.
 196
 197           If you say N here, the kernel will run on single and multiprocessor
 198           machines, but will use only one CPU of a multiprocessor machine. If
 199           you say Y here, the kernel will run on many, but not all,
 200           singleprocessor machines. On a singleprocessor machine, the kernel
 201           will run faster if you say N here.
