OK, got it! Thanks for this clarification.

So, I will try to start to port PAX_REFCOUNT arm-specific features to
hardened_atomic_on_next, and keep you in touch. Is there a deadline?
(4.10 / 5.0 merge window?)

Just to be sure, the patch [1] and documentation [2] of PaX are still
up-to-date, or there is another references I missed?

Thanks

Colin
