Subject: irqchip/eznps: Acknowledge NPS_IPI before calling the handler

From: Noam Camus <[email protected]>

commit c0ca8df717061ae3d2ea624024033103c64210ae upstream.

IPI_IRQ (also TIMER0_IRQ) should be acked before the action->handler is called in handle_percpu_devid_irq.

The IPI irq is edge sensitive and we might miss an IPI interrupt if it is triggered again while the handler runs.
