So I had the bright idea before committing to check if atomic_testandset/clear is actually implemented on all architectures, and it isn't (yet?). I would like to commit this patch anyway and just hold off on D22703. That way we won't break any builds (this patch alone is not yet connected to anything) but I can reduce my patch stack a little. Sound okay?
No objection from me.
If any of the missing archs are sparc64, 32-bit mips, 32-bit arm v5 (and maybe v6...), don't feel obligated to add the support. They're all slated for death on 2020-01-01 anyway.
