Whenever an interrupt triggers, the lowlevel arch code calls into
the generic interrupt code by calling desc->handle_irq().
- This highlevel IRQ handling function only uses desc->chip primitives
- referenced by the assigned chip descriptor structure.

This handler turned out to be not suitable for all

- To make use of the split implementation, replace the call to

- the appropriate handler function to desc->handle_irq().
