This patch is ok, but this approach is fundamentally broken. 
Only 19 architectures use GENERIC_HARDIRQS

The only required interface is interrupt.h not irq.h

So you may not replace NR_IRQS with nr_irqs in anything other
then genirq code and some architecture code.

Doing so will break the build on several architectures.
