This series looks pretty good to me, but I'm not sure about this patch.

It seems like quite a small divergence in terms of code, and it looks
like the final result still has some ifdefs in these functions. Maybe
you could just keep existing behaviour for this cleanup series so it
does not risk triggering some obscure regression? Merging behaviour
could be proposed at the end.

Thanks,
Nick
