[PATCH 5/7] turbostat: rename num_cores_per_pkg to num_cores_per_node

From: Prarit Bhargava
Date: Sun Jul 16 2017 - 16:50:30 EST


turbostat incorrectly assumes that there is one node per package. As a
result num_cores_per_pkg is not correctly named and is actually
num_cores_per_node.

Rename num_cores_per_pkg to num_cores_per_node.
