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" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: virtio_pci: restore module attributes mic/host: fix up virtio 1.0 APIs vringh: update for virtio 1.0 APIs vringh: 64 bit features tools/virtio: add virtio 1.0 in vringh_test tools/virtio: add virtio 1.0 in virtio_test tools/virtio: enable -Werror tools/virtio: 64 bit features tools/virtio: fix vringh test tools/virtio: more stubs virtio: core support for config generation virtio_pci: add VIRTIO_PCI_NO_LEGACY virtio_pci: move probe to common file virtio_pci_common.h: drop VIRTIO_PCI_NO_LEGACY virtio_config: fix virtio_cread_bytes virtio: set VIRTIO_CONFIG_S_FEATURES_OK on restore
