Valentine Barshak c80905637e [POWERPC] 4xx: make UIC use generic level irq handler This patch makes PowerPC 4xx UIC use generic level irq handler instead of a custom handle_uic_irq() function. We ack only edge irqs in mask_ack callback, since acking a level irq on UIC has no effect if the interrupt is still asserted by the device, even if the interrupt is already masked. So, to really de-assert the interrupt we need to de-assert the external source first and ack it on UIC then. The handle_level_irq() function masks and ack's the interrupt with mask_ack callback prior to calling the actual ISR and unmasks it at the end. So, to use it with UIC interrupts we need to ack level irqs in the unmask callback instead, after the ISR has de-asserted the external interrupt source. Even if we ack the interrupt that we didn't handle (unmask/ack it at the end of the handler, while next irq is already pending) it will not de-assert the irq, untill we de-assert its exteral source.
