x86, mcheck: Use correct cpumask for shared bank4
This fixes threshold_bank4 support on multi-node processors. The correct mask to use is llc_shared_map, representing an internal node on Magny-Cours. We need to create 2 sets of symlinks for sibling shared banks -- one set for each internal node, symlinks of each set should target the first core on same internal node. Currently only one set is created where all symlinks are targeting the first core of the entire socket. Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: H.
