In ip_tunnel_rcv(), set skb->network_header to inner IP header
before IP_ECN_decapsulate().
Without the fix, IP_ECN_decapsulate() takes outer IP header as
inner IP header, possibly causing error messages or packet drops.
Note that this skb_reset_network_header() call was in this spot when
the original feature for checking consistency of ECN bits through
tunnels was added in eccc1bb8d4 ("tunnel: drop packet if ECN present
with not-ECT"). It was only removed from this spot in 3d7b46cd20
("ip_tunnel: push generic protocol handling to ip_tunnel module.").

Intel Wired LAN Driver Updates
This series contains updates to e1000e only.
David provides four fixes for e1000e, first is a workaround for a hardware
erratum on 82579 devices which experienced packet loss in gigabit and 100
speeds when interconnect between the PHY and MAC is exiting K1 power saving
state. Second expands the scope of a workaround to include i217 and i218
parts as well to address over aggressive transmit behavior when connecting
at 10Mbs half-duplex. Next is to resolve a reported link flap issue on
82579 parts which was root caused as an interoperability problem between
82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake
mechanism. Lastly, restricts the workaround of putting the PHY into MDIO
slow mode to access the PHY id to relevant parts since this issue has been
fixed on the newer hardware.

It has been determined that the workaround of putting the PHY into MDIO
slow mode to access the PHY id is not necessary with Lynx Point and newer
parts. The issue that necessitated the workaround has been fixed on the
newer hardware.
We will maintains, as a last ditch attempt, the conversion to MDIO Slow
Mode in the failure branch when attempting to access the PHY id so as to
cover all contingencies.

Several customers have reported a link flap issue on 82579. The symptoms
are random and intermittent link losses when 82579 is connected to specific
link partners. Issue has been root caused as interoperability problem
between 82579 and at least some Broadcom PHYs in the Energy Efficient
Ethernet wake mechanism.
To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
Low Power Idle. This solution will cause an increase of power in 100M EEE
link. It will cost additional 28mW in this specific mode.

The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"
Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

Commit 4d619f625a ("net: cdc_ncm: no point in filling up the NTBs
if we send ZLPs") changed the padding logic for devices with the ZLP
flag set. This meant that frames of any size will be sent without
additional padding, except for the single byte added if the size is
a multiple of the USB packet size. But if the unpadded size is
identical to the maximum frame size, and the maximum size is a
multiplum of the USB packet size, then this one-byte padding will
overflow the buffer.
Prevent padding if already at maximum frame size, letting usbnet
transmit a ZLP instead in this case.

[PATCH v3 1/2] device_cgroup: check if exception removal is allowed
When the device cgroup hierarchy was introduced in
bd2953ebbb - devcg: propagate local changes down the hierarchy
a specific case was overlooked. Consider the hierarchy bellow:
A default policy: ALLOW, exceptions will deny access
\
B default policy: ALLOW, exceptions will deny access
There's no need to verify when an new exception is added to B because
in this case exceptions will deny access to further devices, which is
always fine. Hierarchy in device cgroup only makes sure B won't have
more access than A.
But when an exception is removed (by writing devices.allow), it isn't
checked if the user is in fact removing an inherited exception from A,
thus giving more access to B.
Example:
# echo 'a' >A/devices.allow
# echo 'c 1:3 rw' >A/devices.deny
# echo $$ >A/B/tasks
# echo >/dev/null
-bash: /dev/null: Operation not permitted
# echo 'c 1:3 w' >A/B/devices.allow
# echo >/dev/null
#
This shouldn't be allowed and this patch fixes it by making sure to never allow
exceptions in this case to be removed if the exception is partially or fully
present on the parent.

Since commit 1df5a06a ("ALSA: hda - hdmi: Fix programmed active channel
count") channel count is no longer being set if monitor_present is 0.
This is because setting the count was moved after the CA value is
determined, which is only after the monitor_present check in
hdmi_setup_audio_infoframe().
Unfortunately, in some cases, such as with a non-spec-compliant codec or
with a problematic video driver, monitor_present is always 0. As a
specific example, this seems to happen with gen1 ATV (SiI1390 codec),
causing left-channel-only stereo playback (multi-channel playback has
apparently never worked with this codec despite it reporting 8 channels,
reason unknown).
Simply setting converter channel count without setting the pin infoframe
and channel mapping as well does not theoretically make much sense as
this will just mean they are out-of-sync and multichannel playback will
have a wrong channel mapping.
However, adding back just setting the converter channel count even in
no-monitor case is the safest change which at least fixes the stereo
playback regression on SiI1390 codec. Do that.

Commit 54397d8534
("ARM: kirkwood: Relocate PCIe device tree nodes")
moved the pcie-controller nodes for the Kirkwood SoCs to the mbus
bus node. For some reason, two boards were not properly converted
and have their pci-controller nodes still in the ocp bus node.
As the corresponding SoC pcie-controller does not exist anymore,
it is likely that pcie is broken on those boards since above commit.
Fix it by moving the pcie related nodes to the correct location.

It's caused by a silicon issue that SATA phy does not get reset by
controller when coming back from LPM. The patch adds a software
workaround for this issue. It enforces a software reset on SATA phy
in imx_sata_enable() function, so that we can ensure SATA link will
come up properly in both power-on and resume.
The software reset is implemented by writing phy reset register through
the phy control register bus interface. Functions
imx_phy_reg_[addressing|write|read]() implement this bus interface, while
imx_sata_phy_reset() performs the actually reset operation.
