On Arm platform, no 'core id' and 'physical id' in '/proc/cpuinfo'.
So we should search sysfs cpu path directly to get the data of
'thread_id' &'core_id' & 'node_id'.
This method can also be used on other platforms, such as x86, ppc64le...
/sys/bus/cpu/devices/cpu%d contains the information of 'core_id' & 'node_id'.
Such as:
cat /sys/bus/cpu/devices/cpu0/topology/core_id
ls /sys/bus/cpu/devices/cpu0/node0
