The call_single_queue can contain (two) different callbacks, synchronous and asynchronous. The current interrupt handler runs them in-order, which means that remote CPUs that are waiting for their synchronous call can be delayed by running asynchronous callbacks. Rework the interrupt handler to first run the synchonous callbacks.
