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

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

 173           compatibility with 32bit applications, a page size of 4KB should be
 174           selected (the vast majority of 32bit binaries work perfectly fine

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