    genirq: Add IRQ_SET_MASK_OK_DONE to support stacked irqchip · 2cb62547
    Jiang Liu authored
    Add IRQ_SET_MASK_OK_DONE in addition to IRQ_SET_MASK_OK and
    IRQ_SET_MASK_OK_NOCOPY to support stacked irqchip. IRQ_SET_MASK_OK_DONE
    is the same as IRQ_SET_MASK_OK to irq core. To stacked irqchip, it means
    that ascendant irqchips have done all the work and no more handling
    needed in descendant irqchips.
