Agreed that it's not needed here.
There's a non-trivial chance of name collisions between new families 
and existing headers under include/uapi/linux. Since this is a C/C++
-only artifact and "modern" languages will simply ignore it allowing it
seemed like the right choice.

Everything you have as u64 should now be uint, and pads can then go
away.
