And according to that argument of yours, we should move everything
which is not too close to the arch it is being used on, to generic
include/linux/. Because it might possibly get used some day by other
arches. Yeah right.

And looking at include/linux - it looks like a dumping ground for
headers. :-\

I guess anything is better than putting non-generic enough stuff in
include/linux/. Maybe drivers/include or something in that direction
would be better...
