Just to remind that we have there shared interrupt source (which can be requested by more HW drivers) and consumer is PCIe INTX which is de-facto chained handler. And I have not seen anything for shared interrupt source except request_irq(IRQF_SHARED) which you do not want to use for shared interrupts anymore. Also setting of PCIe INTX affinity is broken which worked fine with the previous kernel versions. And you also rejected fixes for this regression.
