Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull virtio fixes from Michael S. Tsirkin:
"virtio oops fixes
The virtio pci rework using shared interrupts caused a lot of issues.
We tried to fix them but run out of time. Revert for now, and revisit
the issue for the next kernel.
Luckily we are able to do this without loosing automatic interrupt
NUMA affinity which was the main motivator for the rework"

virtio-pci: Remove affinity hint before freeing the interrupt
Revert "virtio_pci: remove struct virtio_pci_vq_info"
Revert "virtio_pci: use shared interrupts for virtqueues"
Revert "virtio_pci: don't duplicate the msix_enable flag in struct pci_dev"
Revert "virtio_pci: simplify MSI-X setup"
Revert "virtio_pci: fix out of bound access for msix_names"
MAINTAINERS: fix virtio file pattern
