I'm about to send patch 2(adding trivial tests) as a patch for the tip
tree, and rest of this series will be patches for powerpc next.

Will, AFAIK, you are currently working on variants on arm64, right? I
wonder whether you depend on patch 3 (allow archictures to provide
self-defined __atomic_op_*), if so I can also send patch 3 as a patch
for tip tree and wait until it merged into powerpc next to send the
rest. 

Thanks and Best Regards,
