Agreed. We won´t be able to test and push something like that before vacation but feel free to test
that change and commit it if it works. Otherwise we'll fix it after vacations.

Nope. Also only happens on cris, which has in
arch/cris/include/asm/posix_types.h:

typedef long __kernel_ssize_t;

The "long" should be "int".
But probably it should just include <asm-generic/posix_types.h> instead.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
