summary: Make domctl/sysctl interfaces 32-/64-bit invariant.
It lifted the interface version to 5 which fits to the
I verified my endian/32/64bit based assumption.
Time runs short today - in order that no one overlooks the questions I
hope to read some comments on monday I put them here to the head ;)
- Do we need a compat wrapper for the syscall here? Or do we have one
already, but it is not used?

but all the pointers/structures need to be valid.
It is also a union so the effect of having the same adresses
This is how the adresses are passed through the stack:
