While exploring the asm-*/types.h files, I discovered that the
type "kmem_bufctl_t" is differently defined across each platform,
sometimes as a short, and sometimes as an int. The only file
where it's used is mm/slab.c, and as far as I can tell, that file
doesn't care at all, aside from preferring it to be a small-sized
type.

I don't think there's any good reason for this. -mm's
slab-leak-detector.patch switches them all to unsigned long.

What about moving it to include/linux/types.h ?

Or, since it's _only_ used in mm/slab.c, why not put it in there?
Here is a really simple patch that does just that:
