Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull vhost fixes from Michael Tsirkin: "Fixes all over the place. A new UAPI is borderline: can also be considered a new feature but also seems to be the only way we could come up with to fix addressing for userspace - and it seems important to switch to it now before userspace making assumptions about addressing ability of devices is set in stone" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: vdpasim: allow to assign a MAC address vdpasim: fix MAC address configuration vdpa: handle irq bypass register failure case vdpa_sim: Fix DMA mask Revert "vhost-vdpa: fix page pinning leakage in error path" vdpa/mlx5: Fix error return in map_direct_mr() vhost_vdpa: Return -EFAULT if copy_from_user() fails vdpa_sim: implement get_iova_range() vhost: vdpa: report iova range vdpa: introduce config op to get valid iova range
