Finally got around trying this one. Yeah it's nice and it seems
that this is how we could also allow add support for showing the
time when the wakeirq triggered and was actually seen by the irq
subsystem. I think that's what people have been after for a
while :)

It seems we should do both /sys/kernel/irq/*/wakeup and also
have a name for the dedicated wakeirqs. I'll send out my
kasprintf updated patch shortly.

Regards,

Tony
