 102           This is the processor type of your CPU.  This information is
 103           used for optimizing purposes.  In order to compile a kernel
 104           that can run on all 32-bit PA CPUs (albeit not optimally fast),
 105           you can specify "PA7000" here.

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

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

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