I pulled this, built and booted my x86-dt box and nothing exploded so far.

If you merge Linus' tree then you will get a conflict (sooner or later) in
ioapic_of_irq_map() in arch/x86/kernel/devicetree.c:

-       return io_apic_setup_irq_pin_once(*out_hwirq, cpu_to_node(0), &attr);
  -      if (io_apic_setup_irq_pin(hwirq, cpu_to_node(0), &attr))
++      if (io_apic_setup_irq_pin_once(hwirq, cpu_to_node(0), &attr))
