Rather than making a generic equivalent memcpy function, why not have something which only takes aligned data. And to avoid user confusion change the name to be something not suggestive of memcpy. Maybe rte_non_cache_copy()? Want to avoid the naive user just doing s/memcpy/rte_memcpy_nt/ and expect everything to work.
