The primary objective of this patch series is to change the behaviour of pci_alloc_irq_vectors_affinity() such that it forwards the MSI-X enable error code when appropriate. In the process, though, it was pointed out that there are multiple places in the kernel which check/ask for message signalled interrupts (MSI or MSI-X), which spawned the first patch adding PCI_IRQ_MSI_TYPES. Finally the rest of the chain converts all users to take advantage of PCI_IRQ_MSI_TYPES or PCI_IRQ_ALL_TYPES, as appropriate.
