When I revert a09b659cd68c10ec6a30cb91ebd2c327fcd5bfe5 ("genirq: Fix
long-term regression in genirq irq_set_irq_type() handling") on top of
3.4-rc1 the sata irq errors disappear, but I see a lot of spurious
interrupts.  Also the X server is broken somehow, though I don't know
whether that is related or a different bug.
