If you mostly care about new extensions, we can ignore all the
user ABI headers for now and find a solution that just deals with
the kernel internal ones.

I think the easiest way to do that would be to move all non-exported
headers from include/asm-generic to include/asm. Since it's only about
internel users then, we can simply use "#include_next <asm/foo.h>"
to refer to them from arch-specific files that want to reuse them
only partially and also add some of their own definitions.
