Thanks Thomas, reworded as followed:

    ARM: irq: introduce entry and exit functions for chained handlers
    
    Some chained IRQ handlers are written to cope with primary chips of
    potentially different flow types. Whether this a sensible thing to do
    is a point of contention.
    
    This patch introduces entry/exit functions for chained handlers which
    infer the flow type of the primary chip as fasteoi or level-type by
    checking whether or not the ->irq_eoi function pointer is present and
    calling back to the primary chip as necessary. Other methods of flow
    control are not considered.

I'll add your Ack and put this (patch 1) in Russell's patch system next
week.
