SubjectRe: [PATCH] irq: Add a new IRQF_ACK_BEFORE_UNMASK irq flag
* Thomas Gleixner | 2014-03-12 11:38:24 [+0100]:

>Untested patch below.
Tested-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

on DA850 / OMAP-L138. Without:
59: 560 cp_intc ohci_hcd:usb2
with the patch
59: 280 cp_intc ohci_hcd:usb2

that makes a difference of 280 interrupts. Prior the patch each
interrupt was handled twice and returned once with IRQ_HANDLED and the
second time with IRQ_NONE. With the proper EOI ack I don't see the
IRQ_NONE anymore.

Sebastian
