That was my idea, but your minimal patch from last night looks awfully
attractive, and maybe it's not worth moving it to arch/x86. I do think we
could simplify the code significantly by getting rid of the kzalloc and
acpi_irq_penalty_list from acpi_irq_set_penalty(). How about pushing on
that a little bit first, and see what it looks like then?
