So as Glauber said the reason was that we wanted to use simply
operators, and IIRC he wanted to add a few fields that had to be u64.

I'm not sure what the current plans are wrt adding more fields, but with
your work cputime_t should again be a simple type and thus regular math
operators should work again, right?

Glauber, do you still need to add fields?
