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.
It doesn't really need to do that. I can drop that change, but you
will need to either enable sparse irq or make that number larger if
you ever set up cascaded interrupt controllers.
I have never seen cascaded interrupt controllers on Microblaze system
that's why it is better to have simpler/faster code.

This builds on top of my irq_domain tree:
git://git.secretlab.ca/git/linux-2.6 irqdomain/next
v2: Turn off SPARSE_IRQ because we don't need it.
Is this all that you changed? Do I need to drop the version in my
tree to pick up this version of the patch, or am I okay to simply drop
the SPARSE_IRQ hunk?
Not only that. In second email you see that changes about concurrent irq.
Thanks,
Michal
