[PATCH v2 0/7] vhost: ensure virtqueue access status is checked

[Maxime Coquelin]

Li Feng initially reported segmentation fault in rte_vhost_vring_call()
because of not checking the virtqueue metadata can be accessed.

This should be achieved by checking the access_ok status field of
the virtqueue.

This series also takes the opportunity to fix the other APIs.
This is split in multiple patches to ease LTS maintainers backports,
but could be squashed if preferred.

Changes in v2:
--------------
- Rebased to apply on -rc1 (David)
- Add Fixes tag in patch 1 (David)
- Fix various typos in commit logs (David)

  vhost: fix missing vring call check on virtqueue access
