Compiling an application against it with -Werror and -Wcast-align may trigger cast-align warnings. To avoid those, add first (void *) castings. Note: for eal/arm64 similar changes could be applied to lib/eal/arm/include/rte_memcpy_64.h. I do not have a system in which I encounter such warnings, so currently I do not post any change for it.
