I can tell you what cannot happen. You absolutely can't consider
ideas like using '__u32 val[2];' and accessor macros, long long or
whatever type the platform uses for __u64 has different alignment
constraints than the '__u32 val[2]' array thing would.

I believe there is a way to work around this by using the
__extension__ keyword when defining the __u64 typedefs. Someone
should try playing with that. But this is only going to work when
the compiler is GCC.
