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.
