Would be good to know how much of that actuall is used. Except for that the major users is iBCS which became linux-abi long time ago. I think someone is still keeing it on life support and occasionally forward porting it, but that's not a reason to keep any of this in tree. Back when I maintained it linux-abi already was a large patch to core code and not just modules, and I doubt that has changed in the last 10 years.
