Will respin the series with required fixes.

This looks like it would need an #ifdef check for either
__SIZEOF_INT128__ or CONFIG_ARCH_SUPPORTS_INT128, otherwise
it will fail to build on all 32-bit architectures and possibly
old compiler versions on some 64-bit ones. I think I checked
in the past which targets support __u128, but I don't remember
the result.

Sure, will go with CONFIG_ARCH_SUPPORTS_INT128 and add required #ifdefs here.
