Pull virtio updates from Michael Tsirkin:
 "Just fixes and cleanups this time around. The mapping cleanups are
  preparing the ground for new features, though"

* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
  virtio-vdpa: Drop redundant conversion to bool
  vduse: Use fixed 4KB bounce pages for non-4KB page size
  vduse: switch to use virtio map API instead of DMA API
  vdpa: introduce map ops
  vdpa: support virtio_map
  virtio: introduce map ops in virtio core
  virtio_ring: rename dma_handle to map_handle
  virtio: introduce virtio_map container union
  virtio: rename dma helpers
  virtio_ring: switch to use dma_{map|unmap}_page()
  virtio_ring: constify virtqueue pointer for DMA helpers
  virtio_balloon: Remove redundant __GFP_NOWARN
  vhost: vringh: Fix copy_to_iter return value check
