Is it actually useful to keep both versions? It seems we could just use the u8
version everywhere. Note that there aren't actually any unaligned memory
accesses, so choosing the version conditionally on
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS seems odd. What are you trying to
determine by checking that?
