[PATCH v1 2/2] genirq: support multiple IRQ notifier.

At current implementation, it only supports one IRQ notifier for irq_desc. When if we try to register another IRQ notifier, it automatically un-register previous one and register new one. With this patch, multiple IRQ notifier is supported. Signed-off-by: Weongyo Jeong --- drivers/infiniband

[PATCH v1 0/2] genirq: support multiple IRQ notifier.
