 "Highlights:

   1) Support more Realtek wireless chips, from Jes Sorenson.

   2) New BPF types for per-cpu hash and arrap maps, from Alexei
      Starovoitov.

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as
      well.

   8) Add and use SKB bulk free infrastructure, from Jesper Brouer.

   9) Allow offloading u32 classifiers to hardware, and implement for
      ixgbe, from John Fastabend.

  10) Allow configuring IRQ coalescing parameters on a per-queue basis,
      from Kan Liang.

  11) Extend ethtool so that larger link mode masks can be supported.
      From David Decotigny.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage
      of that in various ways.  From Edward Cree"

d7d5a43c0d ARM: mvebu: fix overlap of Crypto SRAM with PCIe memory window
When the Crypto SRAM mappings were added to the Device Tree files
describing the Armada XP boards in commit c466d997bb ("ARM: mvebu:
define crypto SRAM ranges for all armada-xp boards"), the fact that
those mappings were overlaping with the PCIe memory aperture was
overlooked. Due to this, we currently have for all Armada XP platforms
a situation that looks like this:

Memory mapping on Armada XP boards with internal registers at
0xf1000000:

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory aperture
 - 0xf8100000 -> 0xf8110000	64KB	Crypto SRAM #0	=> OVERLAPS WITH PCIE !
 - 0xf8110000 -> 0xf8120000	64KB	Crypto SRAM #1	=> OVERLAPS WITH PCIE !
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O aperture
 - 0xfff0000  -> 0xffffffff	1M	BootROM

The overlap means that when PCIe devices are added, depending on their
memory window needs, they might or might not be mapped into the
physical address space. Indeed, they will not be mapped if the area
allocated in the PCIe memory aperture by the PCI core overlaps with
one of the Crypto SRAM. Typically, a Intel IGB PCIe NIC that needs 8MB
of PCIe memory will see its PCIe memory window allocated from
0xf80000000 for 8MB, which overlaps with the Crypto SRAM windows. Due
to this, the PCIe window is not created, and any attempt to access the
PCIe window makes the kernel explode:

[    3.302213] igb: Copyright (c) 2007-2014 Intel Corporation.
[    3.307841] pci 0000:00:09.0: enabling device (0140 -> 0143)
[    3.313539] mvebu_mbus: cannot add window '4:f8', conflicts with another window
[    3.320870] mvebu-pcie soc:pcie-controller: Could not create MBus window at [mem 0xf8000000-0xf87fffff]: -22
[    3.330811] Unhandled fault: external abort on non-linefetch (0x1008) at 0xf08c0018

This problem does not occur on Armada 370 boards, because we use the
following memory mapping (for boards that have internal registers at
0xf1000000):

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0 => OK !
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

Obviously, the solution is to align the location of the Crypto SRAM
mappings of Armada XP to be similar with the ones on Armada 370, i.e
have them between the "internal registers" area and the beginning of
the PCIe aperture.

However, we have a special case with the OpenBlocks AX3-4 platform,
which has a 128 MB NOR flash. Currently, this NOR flash is mapped from
0xf0000000 to 0xf8000000. This is possible because on OpenBlocks
AX3-4, the internal registers are not at 0xf1000000. And this explains
why the Crypto SRAM mappings were not configured at the same place on
Armada XP.

Hence, the solution is two-fold:

 (1) Move the NOR flash mapping on Armada XP OpenBlocks AX3-4 from
     0xe8000000 to 0xf0000000. This frees the 0xf0000000 ->
     0xf80000000 space.

 (2) Move the Crypto SRAM mappings on Armada XP to be similar to
     Armada 370 (except of course that Armada XP has two Crypto SRAM
     and not one).

After this patch, the memory mapping on Armada XP boards with
registers at 0xf1 is:

 - 0x00000000 -> 0xf0000000	3.75G 	RAM
 - 0xf0000000 -> 0xf1000000	16M	NOR flashes (AXP GP / AXP DB)
 - 0xf1000000 -> 0xf1100000	1M	internal registers
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
 - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

And the memory mapping for the special case of the OpenBlocks AX3-4
(internal registers at 0xd0000000, NOR of 128 MB):

 - 0x00000000 -> 0xc0000000	3G 	RAM
 - 0xd0000000 -> 0xd1000000	1M	internal registers
 - 0xe800000  -> 0xf0000000	128M	NOR flash
 - 0xf1100000 -> 0xf1110000	64KB	Crypto SRAM #0
 - 0xf1110000 -> 0xf1120000	64KB	Crypto SRAM #1
 - 0xf8000000 -> 0xffe0000	126M	PCIe memory
 - 0xffe00000 -> 0xfff00000	1M	PCIe I/O
 - 0xfff0000  -> 0xffffffff	1M	BootROM

0d9179fb33 ARM: mvebu: remove clock-frequency of serial port Device Tree nodes
Now that the Armada 370/375/38x/XP SoC-level Device Tree files have
the proper "clocks" property in their UART controllers node, it is no
longer useful to have the clock-frequency property defined in the
board-level Device Tree files.

Therefore, this commit gets rid of all the useless 'clock-frequency'
properties.

6e20bae8a3 ARM: mvebu: fix NOR bus-width in Armada XP OpenBlocks AX3 Device Tree
The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus
width declared in the Device Tree being considered as a 16 bits bus
width when configuring the hardware.

This bug in mvebu-devbus driver was compensated by a symetric mistake
in the Armada XP OpenBlocks AX3 Device Tree: a 8 bits bus width was
declared, even though the hardware actually has a 16 bits bus width
connection with the NOR flash.

Now that we have fixed the mvebu-devbus driver to behave according to
its Device Tree binding, this commit fixes the problematic Device Tree
files as well.

This bug was introduced in commit
a7d4f81821 ('ARM: mvebu: Add support for
NOR flash device on Openblocks AX3 board') which was merged in v3.10.

On a more serious note, most of these OS-specific properties aren't

Moving the PCIe nodes, we now need to introduce an extra cell to

the PCIe port, we split the ranges translation entries, to correspond
to each MBus window.

5e12a613ce ARM: mvebu: Add MBus to Armada 370/XP device tree
The Armada 370/XP SoC family has a completely configurable address
space handled by the MBus controller.

This patch introduces the device tree layout of MBus, making the
'soc' node as mbus-compatible.
Since every peripheral/controller is a child of this 'soc' node,
this makes all of them sit behind the mbus, thus describing the
hardware accurately.

A translation entry has been added for the internal-regs mapping.
This can't be done in the common armada-370-xp.dtsi because A370
and AXP have different addressing width.

5f1f3d5088 arm: mvebu: armada-xp-{gp,openblocks-ax3-4}: specify PCIe range
The ranges DT entry needed by the PCIe controller is defined at the
SoC .dtsi level. However, some boards have a NOR flash, and to support
it, they need to override the SoC-level ranges property to add an
additional range. Since PCIe and NOR support came separately, some
boards were not properly changed to include the PCIe range in their
ranges property at the .dts level.

This commit fixes those platforms.

8034891b81 arm: mvebu: enable the third USB interface on OpenBlocks AX3
Besides the two "classic" USB interfaces with normal USB ports on the
front side, the PlatHome OpenBlocks AX3 uses the third USB interface
of the Marvell SoC in the mini-PCIe connector. This allows certain
mini-PCIe cards to expose parts of their functionality as a USB
peripheral.

This commit enables this third USB interface in the OpenBlocks AX3
Device Tree, and also adds comments on top of the two other USB
interfaces so that the Device Tree makes it clear which USB interface
at the SoC level matches which USB interface visible on the board.

to the use of the overload capability of the device tree format,
armada-370 include the 32 bit skeleton and all the armada 370 based

This was heavily based on the work of Lior Amsalem.

This is 3.8 material.

Changes since v2:

 * Renamed the .dts file to armada-xp-openblocks-ax3-4.dts

 * Removed the compatible string from armada-370-xp.c (which now only
   lists the common SoC compatible string)

Changes since v1:

 * Renamed the board to OpenBlocks AX3-4, since there is a variant
   called AX3-2 which has less RAM, and no mini PCIe port. Requested
   by Andrew Lunn.

 * Fix the amount of memory to 3 GB. In fact, the board has 1 GB
   soldered, and 2 GB in a SODIMM slot (which is therefore
   removable). But as the board is delivered as is, we'll assume it
   has 3 GB of memory by default.
