-Subject: [PATCH] irq-bcm2836: Prevent spurious interrupts, and trap them early
-
-The old arch-specific IRQ macros included a dsb to ensure the
-write to clear the mailbox interrupt completed before returning
-from the interrupt. The BCM2836 irqchip driver needs the same
-precaution to avoid spurious interrupts.
-
-Spurious interrupts are still possible for other reasons,
-though, so trap them early.
