Neither #include_next nor the generic/asm approach seems to have a
straightforward way of handling exported user space headers.
The current include/asm-generic way of doing this isn't nice either,
but at least it's a known evil.

Since the question of asm-generic is almost entirely independent of 
where the regular arch headers are, I'd vote for leaving asm-generic
alone for now and only doing the obvious move of all other headers to
arch/*/include/asm as a significant step in the right direction.
Nobody seemed to object that part so far, and the only significant
changes it needs are in sparc64, m68knommu and um as well as a few
scripts changes.
