Re: [PATCH v2] irq_domain/microblaze: Convert microblaze to use irq_domains

From: Grant Likely <grant.likely-s3s/WqlpOiPyB63q8FvJNQ@public.gmane.org>

Move get_irq to asm/irq.h from hardirq.h.

Grant: Why does your patch setup NR_IRQS to 64? It seems to me
pretty big value because intc support up to 32 interrupts.
The main problem was with get_irq function because there must
check status of IVR.
