In order to utilize both paths on dual-ported HBAs we cannot rely on the NUMA affinity alone, but rather have to distribute the locality information to get the best possible result. This patch implements a two-pass algorithm for assinging NUMA locality information: 1. Distribute existing locality information so that no core has more than one 'local' controller 2. Assign a 'local' controller for each of the remaining cores, so that the overall weight (ie the sum of all locality information) per ctrl is minimal.
