    hm. I'd suggest to do this without changing request_irq() - and then we
    could avoid the 'massive, every driver affected' change, right?

    i.e. because we'll (have to) have an nr_to_desc() and desc_to_nr()
    mapping facility anyway, lets just not change the driver APIs massively.
    There dont seem to be that many drivers that assume that irq_desc[] is
    an array - are there?

    otherwise, in terms of the irqchips infrastructure and the API between
    genirq and the irqchip arch-level drivers, this change makes quite a bit
    of sense i think.

    or am i missing something fundamental?
