Ian Campbell c41f680f7d kernel: Update vsock patches to RFC v6
Series is at <1469716595-13591-1-git-send-email-stefanha@redhat.com>.

This corresponds to v7 of the spec, posted in
<1470324277-19300-1-git-send-email-stefanha@redhat.com>

Also add a "cherry-picked from" to the "vsock: make listener child lock
ordering explicit" patch and move it to the head of the series with the other
vsock backports.

Finally backport three new upstream fixes:
3fda5d6e5801 vhost/vsock: fix vhost virtio_vsock_pkt use-after-free
28ad55578b8a virtio-vsock: fix include guard typo
21bc54fc0cdc vhost/vsock: drop space available check for TX vq

These were made on top of the version of the vsock patches which were added to
Linux master in v4.8-rc1. This commit is based on the email posting, will
replace with with proper cherry-pick separately.

Requires corresponding backend changes in Hyperkit

Subject: [PATCH 45/45] vmbus: Don't spam the logs with unknown GUIDs
With Hyper-V sockets device types are introduced on the fly. The pr_info()
then prints a message on every connection, which is way too verbose. Since
there doesn't seem to be an easy way to check for registered services,
disable the pr_info() completely.
