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

 179           At the moment, only people willing to use more than 2GB of RAM,
 180           or having a 64bit-only capable PA-RISC machine should say Y here.
 181
 182           Since there is no 64bit userland on PA-RISC, there is no point to
 183           enable this option otherwise. The 64bit kernel is significantly bigger

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