Pull virtio updates from Michael Tsirkin:

- new virtio CAN driver

- support for LoongArch architecture in fw_cfg

- support for firmware notifications in vdpa/octeon_ep

- support for VFs in virtio core

- fixes, cleanups all over the place, notably:

- vhost: fix vhost_get_avail_idx for a non empty ring
fixing an significant old perf regression

- READ_ONCE() annotations mean virtio ring is now
free of KCSAN warnings

can: virtio: Add virtio CAN driver

Add virtio CAN driver based on Virtio 1.4 specification (see
https://github.com/oasis-tcs/virtio-spec/tree/virtio-1.4). The driver
implements a complete CAN bus interface over Virtio transport,
supporting both CAN Classic and CAN-FD Ids. In term of frames, it
supports classic and CAN FD. RTR frames are only supported with classic
CAN.

Usage:
- "ip link set up can0" - start controller
- "ip link set down can0" - stop controller
- "candump can0" - receive frames
- "cansend can0 123#DEADBEEF" - send frames
