Yeah, I've got a different way to fix it though.  There is exactly one
user of irq_virq_count in-tree right now: PS3.  Also, irq_virq_count
is only useful for the NOMAP mapping.  So, instead of having a single
global irq_virq_count values, I've dropped it entirely and added a
max_irq argument to irq_domain_add_nomap().  That makes it a property
of an individual nomap irq domain instead of a global system settting.

Hopefully I'll have a draft patch ready today. 

That works for me. I'll send patches for cleanup MPIC as well.

Okay, I'll wait on these.  The MPIC fixes will need to be applied
before I can apply the automatic revmapping and hint removal patches.
Those patches will also need testing before I apply to linux-next.
