Can you explain what we gain from this patch?  In the previous discussion,
I mentioned that the parameters LEN and OFFSET in the regcache methods
(e.g. read_part) could be come unsigned, which would allow us to remove
the "offset >= 0 && len >= 0" assertions.  In turn, they won't be
needed in your raw_collect_part/raw_supply_part.  But I don't see
exactly what the current patch brings (though it's not incorrect).
