The rewrite of the interrupt handler includes: o loop until all pending interrupts are handled. This closes a race condition. o count the number of interrupt sources we handled so that we can properly return FILTER_HANDLED or FILTER_STRAY when we break out of the loop. o When matching the interrupt source to the devices that have that source pending, check only from the set of devices we found to have a pending interrupt.
