Pull networking fixes from David Miller:
1) The value choosen for the new SO_MAX_PACING_RATE socket option on
parisc was very poorly choosen, let's fix it while we still can.
From Eric Dumazet.
2) Our generic reciprocal divide was found to handle some edge cases
incorrectly, part of this is encoded into the BPF as deep as the JIT
engines themselves. Just use a real divide throughout for now.
From Eric Dumazet.
3) Because the initial lookup is lockless, the TCP metrics engine can
end up creating two entries for the same lookup key. Fix this by
doing a second lookup under the lock before we actually create the
new entry. From Christoph Paasch.
4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork.
5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting.
From Dan Carpenter.
6) Netlink socket dumping uses the wrong socket state for timewait
sockets. Fix from Neal Cardwell.
7) Fix netlink memory leak in ieee802154_add_iface(), from Christian
Engelmayer.
8) Multicast forwarding in ipv4 can overflow the per-rule reference
counts, causing all multicast traffic to cease. Fix from Hannes
Frederic Sowa.
9) via-rhine needs to stop all TX queues when it resets the device,
from Richard Weinberger.
10) Fix RDS per-cpu accesses broken by the this_cpu_* conversions. From
Gerald Schaefer.

In commit 1ec047eb4751e3 ("ipv6: introduce per-interface counter for
dad-completed ipv6 addresses") I build the detection of the first
operational link-local address much to complex. Additionally this code
now has a race condition.
Replace it with a much simpler variant, which just scans the address
list when duplicate address detection completes, to check if this is
the first valid link local address and send RS and MLD reports then.

Currently compressed audio streams are statically routed from the /dev
to the DAI link. Some DSPs can route compressed data to multiple BE DAIs
like they do for PCM data.
Add support to allow dynamically routed compressed streams using the existing
DPCM infrastructure. This patch adds special FE versions of the compressed ops
that work out the runtime routing.

This patch adds a new field to the dma_slave_caps struct which indicates the
granularity with which the driver is able to update the residue field of the
dma_tx_state struct. Making this information available to dmaengine users allows
them to make better decisions on how to operate. E.g. for audio certain features
like wakeup less operation or timer based scheduling only make sense and work
correctly if the reported residue is fine-grained enough.
Right now four different levels of granularity are supported:
* DESCRIPTOR: The DMA channel is only able to tell whether a descriptor has
been completed or not, which means residue reporting is not supported by
this channel. The residue field of the dma_tx_state field will always be
0.
* SEGMENT: The DMA channel updates the residue field after each successfully
completed segment of the transfer (For cyclic transfers this is after each
period). This is typically implemented by having the hardware generate an
interrupt after each transferred segment and then the drivers updates the
outstanding residue by the size of the segment. Another possibility is if
the hardware supports SG and the segment descriptor has a field which gets
set after the segment has been completed. The driver then counts the
number of segments without the flag set to compute the residue.
* BURST: The DMA channel updates the residue field after each transferred
burst. This is typically only supported if the hardware has a progress
register of some sort (E.g. a register with the current read/write address
or a register with the amount of bursts/beats/bytes that have been
transferred or still need to be transferred).

A bit of special care is necessary when creating the intersection of two rate
masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and
SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two
rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a
specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of
discrete rates specified by a list constraint. For all other cases the supported
rates are specified directly in the rate mask.

The body of i2c_parent_is_i2c_adapter() is currently guarded by
I2C_MUX. It should be CONFIG_I2C_MUX instead.
Among potentially other problems, this resulted in i2c_lock_adapter()
only locking I2C mux child adapters, and not the parent adapter. In
turn, this could allow inter-mingling of mux child selection and I2C
transactions, which could result in I2C transactions being directed to
the wrong I2C bus, and possibly even switching between busses in the
middle of a transaction.
One concrete issue caused by this bug was corrupted HDMI EDID reads
during boot on the NVIDIA Tegra Seaboard system, although this only
became apparent in recent linux-next, when the boot timing was changed
just enough to trigger the race condition.

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:
- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
instead of lower device which misses the necessary txq synchronization for
lower device such as txq stopping or frozen required by dev watchdog or
control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
when tso is disabled for lower device.
Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.
With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.
In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

Nowadays we have CMA for obtaining the contiguous memory pages
efficiently. Let's kill the old kludge for reserving the memory pages
for large buffers. It was rarely useful (only for preserving pages
among module reloading or a little help by an early boot scripting),
used only by a couple of drivers, and yet it gives too much ugliness
than its benefit.

If the regcache is enabled on the regmap module drivers might need to access
to HW register(s) in certain cases in cache bypass mode.
As an example of this is the audio block's ANAMICL register. In normal
operation the content can be cached but during initialization one bit from
the register need to be monitored. With the twl_set_regcache_bypass() the
client driver can switch regcache bypass on and off when it is needed so
we can utilize the regcache for more registers.

ASoC: Updates for v3.14
Not a lot going on framework wise, partly due to Christmas at least in
the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:
- Update to the generic DMA code to support deferred probe and managed
resources.
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs.
- Device tree support for the simple card, max98090 and cs42l52.
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi.
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi.

Pull ACPI and PM fixes and new device IDs from Rafael Wysocki:
"These commits, except for one, are regression fixes and the remaining
one fixes a divide error leading to a kernel panic. The majority of
the regressions fixed here were introduced during the 3.12 cycle, one
of them is from this cycle and one is older.
Specifics:
- VGA switcheroo was broken for some users as a result of the
ACPI-based PCI hotplug (ACPIPHP) changes in 3.12, because some
previously ignored hotplug events started to be handled. The fix
causes them to be ignored again.
- There are two more issues related to cpufreq's suspend/resume
handling changes from the 3.12 cycle addressed by Viresh Kumar's
fixes.
- intel_pstate triggers a divide error in a timer function if the
P-state information it needs is missing during initialization.
This leads to kernel panics on nested KVM clients and is fixed by
failing the initialization cleanly in those cases.
- PCI initalization code changes during the 3.9 cycle uncovered BIOS
issues related to ACPI wakeup notifications (some BIOSes send them
for devices that aren't supposed to support ACPI wakeup). Work
around them by installing an ACPI wakeup notify handler for all PCI
devices with ACPI support.
- The Calxeda cpuilde driver's probe function is tagged as __init,
which is incorrect and causes a section mismatch to occur during
build. Fix from Andre Przywara removes the __init tag from there.
- During the 3.12 cycle ACPIPHP started to print warnings about
missing _ADR for devices that legitimately don't have it. Fix from
Toshi Kani makes it only print the warnings where they make sense"

VM to VM GSO traffic is broken if it goes through VXLAN or GRE
tunnel and the physical NIC on the host supports hardware VXLAN/GRE
GSO offload (e.g. bnx2x and next-gen mlx4).
Two issues -
(VXLAN) VM traffic has SKB_GSO_DODGY and SKB_GSO_UDP_TUNNEL with
SKB_GSO_TCP/UDP set depending on the inner protocol. GSO header
integrity check fails in udp4_ufo_fragment if inner protocol is
TCP. Also gso_segs is calculated incorrectly using skb->len that
includes tunnel header. Fix: robust check should only be applied
to the inner packet.
(VXLAN & GRE) Once GSO header integrity check passes, NULL segs
is returned and the original skb is sent to hardware. However the
tunnel header is already pulled. Fix: tunnel header needs to be
restored so that hardware can perform GSO properly on the original
packet.

The SCTP outqueue structure maintains a data chunks
that are pending transmission, the list of chunks that
are pending a retransmission and a length of data in
flight. It also tries to keep the emtpy state so that
it can performe shutdown sequence or notify user.
The problem is that the empy state is inconsistently
tracked. It is possible to completely drain the queue
without sending anything when using PR-SCTP. In this
case, the empty state will not be correctly state as
report by Jamal Hadi Salim <jhs@mojatatu.com>. This
can cause an association to be perminantly stuck in the
SHUTDOWN_PENDING state.
Additionally, SCTP is incredibly inefficient when setting
the empty state. Even though all the data is availaible
in the outqueue structure, we ignore it and walk a list
of trasnports.
In the end, we can completely remove the extra empty
state and figure out if the queue is empty by looking
at 3 things: length of pending data, length of in-flight
data, and exisiting of retransmit data. All of these
are already in the strucutre.

llc_sk(sk)->vR = ++llc_sk(sk)->vR & 0xffffffffffffff7f
... but the order in which the side effects take place is
undefined because there is no intervening sequence point.
As llc_sk(sk)->vR is written in llc_sk(sk)->vR (assignment
left-hand side) and written in ++llc_sk(sk)->vR & 0xffffffffffffff7f
this might possibly yield undefined behavior.
The final value of llc_sk(sk)->vR is ambiguous, because,
depending on the order of expression evaluation, the
increment may occur before, after, or interleaved with
the assignment. In C, evaluating such an expression yields
undefined behavior.
Since we're doing the increment via PDU_GET_NEXT_Vr() macro
and the only place it is being used is from
llc_conn_ac_inc_vr_by_1(), in order to increment vR by 1
with a follow-up optimized modulo, rewrite the expression
into ((vR + 1) & CONST) in order to fix this.

When the vlan code detects that the real device can do TX VLAN offloads
in hardware, it tries to arrange for the real device's header_ops to
be invoked directly.
But it does so illegally, by simply hooking the real device's
header_ops up to the VLAN device.
This doesn't work because we will end up invoking a set of header_ops
routines which expect a device type which matches the real device, but
will see a VLAN device instead.
Fix this by providing a pass-thru set of header_ops which will arrange
to pass the proper real device instead.
To facilitate this add a dev_rebuild_header(). There are
implementations which provide a ->cache and ->create but not a
->rebuild (f.e. PLIP). So we need a helper function just like
dev_hard_header() to avoid crashes.
Use this helper in the one existing place where the
header_ops->rebuild was being invoked, the neighbour code.
With lots of help from Florian Westphal.

This patch adds SRC support to Renesas sound driver.
SRC converts sampling rate between codec <-> cpu.
It needs special codec chip,
or very simple DA/AD converter to use it.
This patch was tested via ak4554 codec,
and supports Gen1 only at this point.
