[PATCH 6/9] virtio: provide a method to get the IRQ affinity mask for a virtqueue
This basically passed up the pci_irq_get_affinity information through
virtio through an optional get_vq_affinity method. It is only implemented
by the PCI backend for now, and only when we use per-virtqueue IRQs.

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

automatic IRQ affinity for virtio
Hi Michael,
this series contains a couple cleanups for the virtio_pci interrupt
handling code, including a switch to the new pci_irq_alloc_vectors
helper, and support for automatic affinity by the PCI layer if the
consumers ask for it. It then converts over virtio_blk to use this
functionality so that it's blk-mq queues are aligned to the MSI-X
vector routing. I have a similar patch in the
