This series causes a little bit of size growth everywhere. It's fatal on nokia_rx51 (and caught via the test script). We can bring nokia_rx51 back under size by disabling the optimized memcpy/memset functions, but that's not ideal. Can we do your changes here in a more size-concious way? Thanks! -- Tom
