In linux kernel since version 4.1 (release Date: 2015-06-21)  
Here we add new hierarchy for CPUs topology.
We got:
Core
Thread
At the new thread level each CPU represent one HW thread.
At highest hierarchy each core contain 16 threads,
any of them seem like CPU from Linux point of view.
All threads within same core share the execution unit of the
core and HW scheduler round robin between them.
