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

 118           Enable this if you want to support 64bit kernel on PA-RISC platform.
 119
 120           At the moment, only people willing to use more than 2GB of RAM,
 121           or having a 64bit-only capable PA-RISC machine should say Y here.
 122
 123           Since there is no 64bit userland on PA-RISC, there is no point to
 124           enable this option otherwise. The 64bit kernel is significantly bigger
 125           and slower than the 32bit one.

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