[PATCH] genirq: x86_64 irq: make vector_irq per cpu
This refactors the irq handling code to make the vectors a per cpu resource so
the same vector number can be simultaneously used on multiple cpus for
different irqs.
This should make systems that were hitting limits on the total number of irqs
much more livable.
[akpm@osdl.org: build fix]
