Most of this work was done by: bob.picco@xxxxxxxxxx Currently, there is only one context domain per-system. This means when wrap occurs we must go through a cpu-count proportional loop in order to invalidate context ids. It also means, that context wraps can occur more frequently. This patchset solves this problem by introducing multiple context domains. By default one context domain per physical core (on most sun4v it is actually one per two cores, because the defined max strands per core is set to 16 to match match T3.).
