4.10 and -stable fix for virtio_blk and virtually mapped stacks
Without this fix attempts to do scsi passthrough on virtio_blk will crash
the system on virtually mapped stacks, which is something happening during
boot with many distros.

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
