Is fixing this actually any harder than just bumping NR_IRQS/NR_PIRQS in Xen
and NR_PIRQS in Linux? Have IRQS and VECTORS got somehow accidentally tied
together in Xen?

The pvops dom0 kernel allocates all irqs dynamically without havingreserved ranges for particular classes of irq, so I think it all comesdown to whether Xen can handle it.
