Similar to -v2 in that it rewrites spin_unlock_wait() for all. The new spin_unlock_wait() provides ACQUIRE semantics to match the RELEASE of the spin_unlock() we waited for and thereby ensure we can fully observe its critical section. This fixes a number (pretty much all) spin_unlock_wait() users. This series pulls in the smp_cond_acquire() rewrite because it introduces a lot of new users of it. All simple spin_unlock_wait() implementations end up being one. New in this series; apart from the fixes from the last posting (s390,tile), is that it moves smp_cond_load_acquire() and friends into asm-generic/barrier.h such that architectures that explicitly do not do load speculation (tile) can override smp_acquire__after_ctrl_dep(). I'm planning on queuing these patches for 4.8. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
