  12           in many of their workstations & servers (HP9000 700 and 800 series,
  13           and later HP3000 series).  The PA-RISC Linux project home page is

  78           This is the processor type of your CPU.  This information is
  79           used for optimizing purposes.  In order to compile a kernel
  80           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  81           you can specify "PA7000" here.
  82
  83           Specifying "PA8000" here will allow you to select a 64-bit kernel
  84           which is required on some machines.

 132           Enable this if you want to support 64bit kernel on PA-RISC platform.
 133
 134           At the moment, only people willing to use more than 2GB of RAM,
 135           or having a 64bit-only capable PA-RISC machine should say Y here.
 136
 137           Since there is no 64bit userland on PA-RISC, there is no point to
 138           enable this option otherwise. The 64bit kernel is significantly bigger
 139           and slower than the 32bit one.

 143         ---help---
 144           This enables support for systems with more than one CPU. If you have
 145           a system with only one CPU, like most personal computers, say N. If
 146           you have a system with more than one CPU, say Y.
 147
 148           If you say N here, the kernel will run on single and multiprocessor
 149           machines, but will use only one CPU of a multiprocessor machine. If
 150           you say Y here, the kernel will run on many, but not all,
 151           singleprocessor machines. On a singleprocessor machine, the kernel
 152           will run faster if you say N here.
