Comparing to the version 1, I have broken it down to 3 smaller patches each modifying single source file. Each of those can be also applied independently.
The first 2 patches in this series modify the waiter/wait_record and multiple-producers single-consumer queue to make them work correctly on weak memory model architectures like ARM. These two constitute the building blocks of the very critical synchronization mechanism in OSv - lock-free mutex. Similarly the 3rd patch modifies synch_thread/synch_port to make it work correctly with weak memory model.
