Yes, I didn't bother replying any further because it seemed that no one
was listening to me.

I think over the four or five emails my position on the patch was pretty
clear: I do _not_ like it one bit, and I still do not like it.

It is a hack, plain and simple.  You're adding code to misrepresent what
the hardware can do.  You're fooling the system into thinking that the
GIC can control wake-up sources, when in fact the GIC has zero wakeup
capabilities what so ever.

As I pointed out in the message above, if you do this, then drivers have
NO WAY to detect whether the interrupt controller they're connected to
is wake-up capable or not.

I still don't know what your driver code looks like, yet I've given you
a suggestion to solve your problem in a subsequent reply (see the URL
at the top of this message) which never really got a reply from you.

It seems to me that as soon as I asked for driver code, ST lost all
interest in discussing the issue any further, as there was no further
technical discussion coming from _any_ ST people.
