automatic IRQ affinity for virtio V2
Hi Michael, hi Jason, This patches applies a few cleanups to the virtio PCI interrupt handling code, and then converts the virtio PCI code to use the automatic MSI-X vectors spreading, as well as using the information in virtio-blk and virtio-scsi to automatically align the blk-mq queues to the MSI-X vectors. Changes since V1: - dropped the patches already merged for 4.10-rc - new patch to
