In linux kernel since version 2.6.12  
This is the processor type of your CPU. This information is
used for optimizing purposes. In order to compile a kernel
that can run on all 32-bit PA CPUs (albeit not optimally fast),
you can specify "PA7000" here.

Specifying "PA8000" here will allow you to select a 64-bit kernel
which is required on some machines.
