The host side VSOCK implementation introduced with
0009-VSOCK-Introduce-vhost_vsock.ko.patch
does not compile due to vhost_vq_init_access not being defined.
VHOST support (including VHOST_VSOCK) was enabled with
86deeaff ("kernel: Bring 4.4 x86_64 kernel config more in line
with 4.9") but not compile tested. Having VHOST support in
itself is fine, it's just the VHOST_VSOCK portion which is not
avail.
