    Nice, we should have unified the compat ptrace code long ago.

    Any chance you could make the ifdef symetric to the native ptrace
    where an arch defines a symbol if it has it's own ptrace?

    Also when prototyping something like this I was wondering whether we
    really want a separate compat function. Lots of the ptrace requests
    mostly depend on the target processes abi, not the ptrace caller, so
    maybe doing it like s390 and handle both in the same function might
    actually be cleaner. Anyway, that's probably something to worry about
    later one the arch-specific compat ptrace implementations are gone.
