Sorry, but I'm not a fan of doing much more work than required instead 
of getting a consensus first and then implementing the solution.

Let's agree on the way to go first, give me two weeks, and I can submit 
a first batch of the header splitting that will both not break any 
kernel code and be enough for compiling most of the userspace.

Perhaps two weeks are too optimistic for some parts considering the 
state of our headers, but getting it done before OLS seems realistic.

But otherwise, I think I have better things to do in the part of my 
spare time I'm devoting to Linux kernel development.
