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

 176           At the moment, only people willing to use more than 2GB of RAM,
 177           or having a 64bit-only capable PA-RISC machine should say Y here.
 178
 179           Since there is no 64bit userland on PA-RISC, there is no point to
 180           enable this option otherwise. The 64bit kernel is significantly bigger

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

 218           This enables support for systems with more than one CPU. If you have
 219           a system with only one CPU, like most personal computers, say N. If
 220           you have a system with more than one CPU, say Y.
 221
 222           If you say N here, the kernel will run on single and multiprocessor
 223           machines, but will use only one CPU of a multiprocessor machine. If
 224           you say Y here, the kernel will run on many, but not all,
 225           singleprocessor machines. On a singleprocessor machine, the kernel
 226           will run faster if you say N here.
