Pull networking fixes from David Miller:
"Here are some bug fixes that have piled up during ksummit/linuxcon.
1) Fix endian problems in ibmveth, from Anton Blanchard.
2) IPV6 routing code does GFP_KERNEL allocation in atomic, fix from
Benjamin Block.
3) SCTP association fixes from Daniel Borkmann.
4) When multiple VLAN headers are present we have to make sure the
second and subsequent ones are pullable in the SKB otherwise we
blindly dereference garbage. From Jiri Benc.
5) The argument adjustment of the signature of hlist_add_after*()
introduced a regression in the batman-adv code, fix from Sven
Eckelmann.
6) Fix TX hang handling to avoid a panic in i40e, from Anjali Singhai
Jain.
7) PTP flag test is inverted in i40e driver, from Jesse Brandeburg.
8) ATM LEC driver needs to hold RTNL mutex over MTU changes, from
Chas Williams.
9) Truncate packets larger then the TPACKET_V3 format configured
buffers, otherwise we overwrite past the end of said buffers.
From Eric Dumazet.
10) Fix endianness bugs in qlcnic firmware handling, from Rajesh
Borundia and Shahed Shaikh.
11) CXGB4 sometimes doesn't get all of the TX completion events it
should resulting in SKBs getting stuck in the TX queue, from
Hariprasad Shenai.
12) When the FEC chip's PTP clock is disabled, you can't access the
register. Add necessary checks to avoid the resulting hang, from
Fugang Duan"

+Toshiba HDD Active Protection Sensor
+====================================
+
+Author: Azael Avalos <coproscefalo@gmail.com>
+
+
+0. Contents
+-----------
+
+1. Description
+2. Interface
+3. Accelerometer axes
+4. Supported devices
+5. Usage
+
+
+1. Description
+--------------
+
+This driver provides support for the accelerometer found in various Toshiba
+laptops, being called "Toshiba HDD Protection - Shock Sensor" officialy,
+and detects laptops automatically with this device.
+On Windows, Toshiba provided software monitors this device and provides
+automatic HDD protection (head unload) on sudden moves or harsh vibrations,
+however, this driver only provides a notification via a sysfs file to let
+userspace tools or daemons act accordingly, as well as providing a sysfs
+file to set the desired protection level or sensor sensibility.
+
+
+2. Interface
+------------
+
+This device comes with 3 methods:
+_STA - Checks existence of the device, returning Zero if the device does not
+ exists or is not supported.
+PTLV - Sets the desired protection level.
+RSSS - Shuts down the HDD protection interface for a few seconds,
+ then restores normal operation.
+
+Note:
+The presence of Solid State Drives (SSD) can make this driver to fail loading,
+given the fact that such drives have no movable parts, and thus, not requiring
+any "protection" as well as failing during the evaluation of the _STA method
+found under this device.
+
+
+3. Accelerometer axes
+---------------------
+
+This device does not report any axes, however, to query the sensor position
+a couple HCI (Hardware Configuration Interface) calls (0x6D and 0xA6) are
+provided to query such information, handled by the kernel module toshiba_acpi
+since kernel version 3.15.
+
+
+4. Supported devices
+--------------------
+
+This driver binds itself to the ACPI device TOS620A, and any Toshiba laptop
+with this device is supported, given the fact that they have the presence of
+conventional HDD and not only SSD, or a combination of both HDD and SSD.
+
+
+5. Usage
+--------
+
+The sysfs files under /sys/devices/LNXSYSTM:00/LNXSYBUS:00/TOS620A:00/ are:
+protection_level - The protection_level is readable and writeable, and
+ provides a way to let userspace query the current protection
+ level, as well as set the desired protection level, the
+ available protection levels are:
+ 0 - Disabled | 1 - Low | 2 - Medium | 3 - High
+reset_protection - The reset_protection entry is writeable only, being "1"
+ the only parameter it accepts, it is used to trigger
+ a reset of the protection interface.
