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!
