This series removes a bogus allocation of a LSI interrupt for the PCI Host Bridge found in the powernv model (phb4). The real hardware doesn't declare any LSI, so the model should match. It was causing some inconsistencies in the interrupt controller data.
However, removing that LSI shows that the PCI AER code assumes an interrupt is defined (LSI or MSI or MSI-X), which is not the case with the root bridge device on powernv. So the last patch adds a check to make sure a LSI is defined before entering pci_set_irq() as it asserts if it's called with no LSI defined.
