Ouch! Unless I misread this code this will leave nr_irqs at
NR_IRQS_LEGACY. aka 16.

Let's do something stupid and simple.
nr_irqs = nr_cpus_ids * 256; /* Semi-arbitrary number */

Ideally we would set "nr_irqs = 0x7fffffff;" but we have just enough
places using nr_irqs that I think those loops would get painful if we
were to do that.
