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

 155           Enable this if you want to support 64bit kernel on PA-RISC platform.

 157           At the moment, only people willing to use more than 2GB of RAM,
 158           or having a 64bit-only capable PA-RISC machine should say Y here.
 159
 160           Since there is no 64bit userland on PA-RISC, there is no point to
 161           enable this option otherwise. The 64bit kernel is significantly bigger
 162           and slower than the 32bit one.

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