  68           This is the processor type of your CPU.  This information is
  69           used for optimizing purposes.  In order to compile a kernel
  70           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  71           you can specify "PA7000" here.
  72
  73           Specifying "PA8000" here will allow you to select a 64-bit kernel

 122           Enable this if you want to support 64bit kernel on PA-RISC platform.
 123
 124           At the moment, only people willing to use more than 2GB of RAM,
 125           or having a 64bit-only capable PA-RISC machine should say Y here.
 126
 127           Since there is no 64bit userland on PA-RISC, there is no point to
 128           enable this option otherwise. The 64bit kernel is significantly bigger
 129           and slower than the 32bit one.

 134           This enables support for systems with more than one CPU. If you have
 135           a system with only one CPU, like most personal computers, say N. If
 136           you have a system with more than one CPU, say Y.
 137
 138           If you say N here, the kernel will run on single and multiprocessor
 139           machines, but will use only one CPU of a multiprocessor machine. If
 140           you say Y here, the kernel will run on many, but not all,
 141           singleprocessor machines. On a singleprocessor machine, the kernel
 142           will run faster if you say N here.
