Hmm. not too much actually, I re-checked v3.10:kernel/copy_process.c.
Yes, list_add(thread_node)) in copy_process() can add the new thread
with the wrong pids, but somehow I forgot that list_add(thread_group)
in v3.10 has the same problem, so this probably doesn't matter and
we can safely backport this change.

Yes, anyway, bacause I will sleep better ;)

But OK, if you think it would be better to mark 1-4 series I sent
for stable - I won't argue.
