 114           used for optimizing purposes.  In order to compile a kernel
 115           that can run on all 32-bit PA CPUs (albeit not optimally fast),

 167           Enable this if you want to support 64bit kernel on PA-RISC platform.
 168
 169           At the moment, only people willing to use more than 2GB of RAM,
 170           or having a 64bit-only capable PA-RISC machine should say Y here.
 171
 172           Since there is no 64bit userland on PA-RISC, there is no point to
 173           enable this option otherwise. The 64bit kernel is significantly bigger
 174           and slower than the 32bit one.

 183           This lets you select the page size of the kernel.  For best
 184           performance, a page size of 16KB is recommended.  For best
 185           compatibility with 32bit applications, a page size of 4KB should be
 186           selected (the vast majority of 32bit binaries work perfectly fine

 209           This enables support for systems with more than one CPU. If you have
 210           a system with only one CPU, like most personal computers, say N. If
 211           you have a system with more than one CPU, say Y.
 212
 213           If you say N here, the kernel will run on single and multiprocessor
 214           machines, but will use only one CPU of a multiprocessor machine. If
 215           you say Y here, the kernel will run on many, but not all,
 216           singleprocessor machines. On a singleprocessor machine, the kernel
 217           will run faster if you say N here.
