Cover letter [PATCH net V3 0/3] Fix various issue of vhost

Hi:

This series tries to fix various issues of vhost:

- Patch 1 adds a missing write barrier between used idx updating and logging.
- Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries.

Please consider them for -stable.

Thanks

Changes from V2:
- drop dirty page fix and make it for net-next
Changes from V1:
- silent compiler warning for 32bit.
- use mutex_trylock() on slowpath instead of mutex_lock() even on fast path.

Jason Wang (3):
vhost: make sure used idx is seen before log in vhost_add_used_n()
vhost_net: switch to use mutex_trylock() in vhost_net_busy_poll() Revert "net: vhost: lock the vqs one by one"
