This series enhances the irq and PCI code to allow spreading around MSI and MSI-X vectors so that they have per-cpu affinity if possible, or at least per-node. For that it takes the algorithm from blk-mq, moves it to a common place, and makes it available through a vastly simplified PCI interrupt allocation API. It then switches blk-mq to be able to pick up the queue mapping from the device if available, and demostrates all this using the NVMe driver. There is still some work todo, mostly related to handling PCI hotplug, more details are in the individual patches. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
