Pull virtio fixes from Michael Tsirkin:
 "This includes a couple of bugfixs for virtio.

  The virtio console patch is actually also in x86/tip targeting 4.9
  because it helps vmap stacks, but it also fixes IOMMU_PLATFORM which
  was added in 4.8, and it seems important not to ship that in a broken
  configuration"
