The old do_fork() is defined only for architectures that are not ready to use this way and do not define HAVE_COPY_THREAD_TLS. 1st patch fixes do_fork() declaration. 2nd patch fixes kprobe samples to work again. BTW: I think about renaming _do_fork() to do_fork_tls(). Then it will use the same naming scheme as copy_thread()/copy_thread_tls().
