Speed blindness during my review... I have now spotted a couple of copy-paste typos:

> +#define rte_atomic_compare_exchange_weak_explicit( \
> +	    ptr, expected, desired, succ_memorder, fail_memorder) \
> +	atomic_compare_exchange_strong_explicit( \

atomic_compare_exchange_weak_explicit, not strong.

> +	    ptr, expected, desired, succ_memorder, fail_memorder)
> +

[...]

> +#define rte_atomic_flag_clear_explicit(ptr, memorder) \
> +	atomic_flag_clear(ptr, memorder)

atomic_flag_clear_explicit(ptr, memorder), missing _explicit.
