Good point.
Looks there is a variable 'nr_cpu_ids' that could be used as well.

If there is general consensus that the patch can help the arm
community, and others in general,
this optimization should be easy to implement - saving few chars space
in each line of console output.

For now i will stick to this v3 version of path, unless you think otherwise.
