NACK! Why should we resolv an issue by reverting it to solve not working
userspace. We already have this patch as a solution for solving a deeper
Problem, regarding the allocator addressing the right device.

So, I think fixing the userspace would be the right fix, not changing
the kernel. Otherwise we should find a proper solution.
