The format and layout of /proc/cpuinfo changes on different architectures,
therefore the DPDK cpu_layout.py tool doesn't work.

Could you please change the tool to use sysfs /sys/devices/system/cpu/cpuN/topology/
instead? Then the script would be portable and use the same files as the DPDK
use internally when mapping out cores.
