tools/power turbostat: rename num_cores_per_pkg to num_cores_per_node
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. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Len Brown <len.brown@intel.com>
