There seems to be syntax for this, at least for stable patches
(which we should probably either use or add +noautosel):

* Specify any additional patch prerequisites for cherry picking::

    xCxc: <stable@...r.kernel.org> # 3.3.x: a1f84a3: sched: Check for idle
    xCxc: <stable@...r.kernel.org> # 3.3.x: 1b9508f: sched: Rate-limit newidle
    xCxc: <stable@...r.kernel.org> # 3.3.x: fd21073: sched: Fix affinity logic
    xCxc: <stable@...r.kernel.org> # 3.3.x
    xSxixgxxnxexd-oxfxf-xbxy: Ingo Molnar <mingo@...e.hu>

(deliberatelly added a bunch of 'x'-es to not interrupt the maintainers'
b4 workflow)
