From torvalds/linux@4192f672fa which was
part of torvalds/linux@v4.7-rc6. The change is purely to ensure that vsock
is lockdep-clean.

AUFS introduces new lockdep relations which are beyond the maximum variants
that lockdep ships with. Without this patch, AUFS triggers lockdep BUG sanity
checks and disables lockdep for the rest of the system.
The present value of the patch is:

Not really required as ports exposed on localhost. If users
want to connext to VM ports they can use the IP address, as
this is discouraged. llmnr names are very slow to access,
so not nice to use.

See #305#301
This sets AWS to use the amazon ntp pool, windows to do nothing,
mac uses ntp it gets from DNS. Azure currently uses default pool,
this probably needs fixing.

This was there to workaround an issue with vmnet, not applicable now.
A user reported that they were getting unexpected 8.8.8.8 addresses
and it could possible be applied erroneously under some circumstances.

Incrementally output log, and exit as soon as tests pass
or fail. Will still timeout on a kernel panic or suchlike
though...
