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

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

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

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