The uuid entry struct is used for the UUID byte stream. That is
actually the wrong value. The correct value is uuid->uuid.
Besides fixing this up, use the %pUb modifier to print the UUID
string. However since the UUID is stored in big endian with
reversed byte order, change the byte order before printing.

The Device Under Test (DUT) mode is useful for doing certification
testing and so expose this as debugfs option.
This mode is actually special since you can only enter it. Restoring
normal operation means that a HCI Reset is required. The current mode
value gets tracked as a new device flag and when disabling it, the
correct command to reset the controller is sent.

Enabling and disabling SSP debug mode is useful for development. This
adds a debugfs entry that allows to configure the SSP debug mode.
On purpose this has been implemented as debugfs entry and not a public
API since it is really only useful during testing and development.

A TT response may be prepared and sent while the local or
global translation table is getting updated.
The worst case is when one of the tables is accessed after
its content has been recently updated but the metadata
(TTVN/CRC) has not yet. In this case the reader will get a
table content which does not match the TTVN/CRC.
This will lead to an inconsistent state and so to a TT
recovery.
To avoid entering this situation, put a lock around those TT
operations recomputing the metadata and around the TT
Response creation (the latter is the only reader that
accesses the metadata together with the table).

With this patch the functions batadv_send_skb_unicast() and
batadv_send_skb_unicast_4addr() are further refined into
batadv_send_skb_via_tt(), batadv_send_skb_via_tt_4addr() and
batadv_send_skb_via_gw(). This way we avoid any "guessing" about where to send
a packet in the unicast forwarding methods and let the callers decide.
This is going to be useful for the upcoming multicast related patches in
particular.
Further, the return values were polished a little to use the more
appropriate NET_XMIT_* defines.

Each VLAN can now have its own set of attributes which are
exported through a new subfolder in the sysfs tree.
Each VLAN created on top of a soft_iface will have its own
subfolder.
The subfolder is named "vlan%VID" and it is created inside
the "mesh" sysfs folder belonging to batman-adv.
Attributes corresponding to the untagged LAN are stored in
the root sysfs folder as before.
This patch also creates all the needed macros and data
structures to easily handle new VLAN spacific attributes.

Since batman-adv is now fully VLAN-aware, a proper framework
able to handle per-vlan-interface attributes is needed.
Those attributes will affect the associated VLAN interface
only, rather than the real soft_iface (which would result
in every vlan interface having the same attribute
configuration).
To make the code simpler and easier to extend, attributes
associated to the standalone soft_iface are now treated
like belonging to yet another vlan having a special vid.
This vid is different from the others because it is made up
by all zeros and the VLAN_HAS_TAG bit is not set.

The same IP subnet can be used on different VLANs, therefore

Pull ACPI and power management fixes from Rafael Wysocki:
- intel_pstate fix for misbehavior after system resume if sysfs
attributes are set in a specific way before the corresponding suspend
from Dirk Brandewie.
- A recent intel_pstate fix has no effect if unsigned long is 32-bit,
so fix it up to cover that case as well.
- The s3c64xx cpufreq driver was not updated when the index field of
struct cpufreq_frequency_table was replaced with driver_data, so
update it now. From Charles Keepax.
- The Kconfig help text for ACPI_BUTTON still refers to
/proc/acpi/event that has been dropped recently, so modify it to
remove that reference. From Krzysztof Mazur.
- A Lan Tianyu's change adds a missing mutex unlock to an error code
path in acpi_resume_power_resources().
- Some code related to ACPI power resources, whose very purpose is
questionable to put it lightly, turns out to cause problems to happen
during testing on real systems, so remove it completely (we may
revisit that in the future if there's a compelling enough reason).

Remove the specialized code in __tcp_retransmit_skb() that tries to trim
any ACKed payload preceding a FIN before we retransmit (this was added
in 1999 in v2.2.3pre3). This trimming code was made unreachable by the
more general code added above it that uses tcp_trim_head() to trim any
ACKed payload, with or without a FIN (this was added in "[NET]: Add
segmentation offload support to TCP." in 2002 circa v2.5.33).

In 3.12 I changed audio to be enabled by default,
but you still had to turn it on via xrandr. This
was confusing to users so change it to minic the
previous behavior:
- audio option is set to -1 (auto) by default which is
the current 3.12 behavior (audio is enabled but requires
xrandr to turn it on).
- if audio = 1, the audio is enabled without needing
to mess with xrandr (previous behavior)
- audio = 0 disables audio
It retains the new feature of allowing the user to enable
audio on the fly with xrandr, but turns audio on
automatically if radeon.audio=1 is set which is what
most users expect.
