Huch? What kind of weird include chain is that?

All (header) files which include that new header have u64 defined.

And building sparc64 allmodconfig does not expose this odd failure
here. The build fails for a reason related to this series, but that's not
caused by that sched/types.h header.

Now it came after fixing the other thing, but that build error is really
weird.
