  60           This is the processor type of your CPU.  This information is
  61           used for optimizing purposes.  In order to compile a kernel
  62           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  63           you can specify "PA7000" here.
  64
  65           Specifying "PA8000" here will allow you to select a 64-bit kernel
  66           which is required on some machines.

 114           Enable this if you want to support 64bit kernel on PA-RISC platform.
 115
 116           At the moment, only people willing to use more than 2GB of RAM,
 117           or having a 64bit-only capable PA-RISC machine should say Y here.
 118
 119           Since there is no 64bit userland on PA-RISC, there is no point to
 120           enable this option otherwise. The 64bit kernel is significantly bigger
 121           and slower than the 32bit one.

 126           This enables support for systems with more than one CPU. If you have
 127           a system with only one CPU, like most personal computers, say N. If
 128           you have a system with more than one CPU, say Y.
 129
 130           If you say N here, the kernel will run on single and multiprocessor
 131           machines, but will use only one CPU of a multiprocessor machine. If
 132           you say Y here, the kernel will run on many, but not all,
 133           singleprocessor machines. On a singleprocessor machine, the kernel
 134           will run faster if you say N here.
