crash utility: add "percpu" command
an invention by ptesarik
Updated over 2 years ago. No love.

Crash has some support for per-cpu variables, but it really only works for static variables. My idea is that you should be able to take a per-cpu pointer and see the formatted data. The syntax should allow to specify a CPU or do it for all:

crash> percpu $CPU <type_name> <address> crash> percpu -a <type_name> <address>

It should also be usable with static variables:

crash> percpu -a <variable_name>

Looking for hackers with the skills:

      This is finished. Upstream doesn't like adding new commands, so it may be re-implemented as options to existing commands instead.

      Accepted as address syntax enhancement (denoted with a ':').
