    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.
