On i386 the hw_irq_controller.end() handler conditionally calls the function registered for the hw_irq_controller.enable() handler [enable_8259A_irq()] which I'd hazard is how the missing hw_irq_controller.end() call went unnoticed. ie: for the i386 the end() call was effectively redundant w/r/t the enable() call. However for PPC there is some specific unfinished business to be done at the logical conclusion of IRQ reception which is accomplished by the registered end() hook. -john -- john.cooper@timesys.com
