Agreed, but IIRC this change should be rebased on top of -mm tree (I sent
the patch which changes send_signal_locked(), and thanks for your review btw!)

And, again iirc, with that patch "make siginfo const" become really trivial,
we only need to add "const" to every "kernel_siginfo *info" in the
send_signal_locked()'s callchain.
