This is a problem. It entirely defeats the point of hwirq_base and it
would break the GIC. We need to fix this in the generic irq chip.

I think I found a fix. Can you try 's/d->hwirq/(d->hwirq % 32)/' in
generic-chip.c.

Needless to try (will try later), this will work.  But again, what do
we need to change 'd->irq - d->irq_base' at all?
