Doing only : np = find_type_devices("cpu"); worked fine. I guess this
will catch any cpus in the system, and be ok. There are not yet
multi-cpu pegasos boxes, so i think it is ok to just check the first CPU
and enable the L2 cache there, i will make sure the OF of future
multi-cpu systems will set the L2 cache properly.
Or is it better to go for the first child of cpus ?
