    I don't think the flag clearing on PTRACE_KILL matters as the process
    is a zombie and almost gone anyway, it's more an artefact of the
    generic implementation that I wanted to mention.

    It seems like avr32 implement single stepping by setting the
    TIF_SINGLE_STEP and TIF_BREAKPOINT thread flags. Simply clearing these
    flags in user_disable_single_step and calling that function from
    ptrace_disable (which currently clears them itself) should take care
    of it.
