While the patch itself is a good catch, I wonder why we iterate over all
IRQs here if we only do something for private IRQs? Can you fix that on
the way as well?
Oh, and while you are at it: ;-)
A comments like: "Set all private IRQs to be edge-triggered and enable
all SGIs." sounds useful to me.

Cheers,
Andre.
