Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost

Pull virtio fixes from Michael S Tsirkin:
 "virtio 1.0 related fixes

  Most importantly, this fixes using virtio_pci as a module.

  Further, the big virtio 1.0 conversion missed a couple of places.
  This fixes them up.

  This isn't 100% sparse-clean yet because on many architectures
  get_user triggers sparse warnings when used with __bitwise tag (when
  same tag is on both pointer and value read).

  I posted a patchset to fix it up by adding __force on all arches that
  don't already have it (many do), when that's merged these warnings
  will go away"
