Without this series, tasks will vary in performance by around +/-30% on POWER7 This new version is based on help from Vatsa and Vaidy in an attempt to answer concerns that Peter Zijlstra had about the original series. The 1st patch is a fix for SMT4 in general. The 2nd adds actual the asymmetrical packing infrastructure. The 3rd adds the powerpc specific hooks for POWER7. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
