Ah, indeed. It turns out that it was my own change that did this:

make most exported headers use strict integer types
This takes care of all files that have only a small number
of non-strict integer type uses.

No, that wouldn't work. The C user space headers are not meant to
be included implicitly by any standard headers, which might pull
in linux/types.h implicitly.
I think it would be best to change all patches in the new series
in the same way for consistency and try to avoid using stdint.h
as much as we can.
