Linus Torvalds d44ade05aa virtio,vhost,vdpa: features, fixes
- 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
     - plus READ_ONCE annotations mean virtio ring is now
       free of KCSAN warnings
