The second hunk is at best bogus: arch_probe_nr_irqs() only gets
referenced from a code section that's inside CONFIG_SPARSE_IRQ, and
when that option is selected, you'll have a duplicate symbol definition
issue between the arch_probe_nr_irqs() in arch/x86/kernel/apic/io_apic.c
and the one in drivers/xen/core/evtchn.c. Additionally, simply enabling
the function in arch/x86/kernel/apic/io_apic.c does not do, as it may
leave you with insufficient space for dynamic IRQs (which is why I
cloned it into a properly working function in drivers/xen/core/evtchn.c).
