  13           and later HP3000 series).  The PA-RISC Linux project home page is

  70           This is the processor type of your CPU.  This information is
  71           used for optimizing purposes.  In order to compile a kernel
  72           that can run on all 32-bit PA CPUs (albeit not optimally fast),
  73           you can specify "PA7000" here.
  74
  75           Specifying "PA8000" here will allow you to select a 64-bit kernel

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

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