no compat layer and type checking will be done
by syscall wrappers. Ok?

Why are you against using strong typing just for everything other
than the user pointer blobs?

I don't understand the resistence to my suggestion to just use
aligned_u64 instead of "void __user *" in the union members.

All these different variants are ok to me. There are pros and
cons to either approach. I'm not against strong typing.
I just thought it would be cleaner not to use 'union' and
was asking for opinion. That's all. Sure, I will keep 'union'
and only change pointers to __aligned_u64.
