Further investigation shows CPU topology already exported to sysfs with 
different way :). And LKML has that discussion before (Ulrich Drepper wants 
to export that information for some glibc/openMPI optimizations which ends up 
with nothing)

So, /sys/devices/system/cpu/cpu*/topology/core_id already exports CPU core 
id's to userspace, for all CPU's if they all 0 that means machine is smt 
capable else its mc capable one.

So attached cleaned/refactored/tested patch introduces "detect_topology" 
function on top of previous one. 

Cheers
