Please take a look. The first patch just cleans up the find_unbound_irq so it is easier to understand what it does.
The second patch hardness the Xen IRQ (event channels) allocation finder if you try to boot a minimalistic 32-bit Linux kernel along with a Xen hypervisor under QEMU.
We end up with a weird scenario where the nr_irq_gsi was greater than nr_irq by 16. This code hardness it by pointing out the issue to the user and tries to continue - BUT this might impact the PCI device allocation.
Tested also on normal machine with no regressions found.
