Thanks for taking up that work, I had a similar patch series
some years ago but never followed through with getting it upstream.
If there are no objections, I hope Andrew can queue it up for -mm.
Unfortunately I can't think of a good way to split up the patch
into smaller units that could go through subsystem maintainer
trees, since we want to start reusing the symbol as soon as possible.
