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

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

 161           At the moment, only people willing to use more than 2GB of RAM,
 162           or having a 64bit-only capable PA-RISC machine should say Y here.
 163
 164           Since there is no 64bit userland on PA-RISC, there is no point to
 165           enable this option otherwise. The 64bit kernel is significantly bigger
 166           and slower than the 32bit one.

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

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