Subject: [PATCH 05/20] x86: mcheck: make use of cpu_node_mask instead of cpu_core_mask to support multi-node processors

From: Andreas Herrmann <andreas.herrmann3@....com>

This fixes threshold_bank4 support.

We need to create symlinks for sibling shared banks to first core of
each internal node and not to first core of one internal node.
