nla_ok() consists of 3 clauses:

	1) int rem >= (int)sizeof(struct nlattr)

	2) u16 nla_len >= sizeof(struct nlattr)

	3) u16 nla_len <= int rem

The statement is that clause (1) is redundant.

What it does is ensuring that "rem" is a positive number,
so that in clause (3) positive number will be compared to positive number
with no problems.

However, "u16" fully fits into "int" and integers do not change value
when upcasting even to signed type. Negative integers will be rejected
by clause (3) just fine. Small positive integers will be rejected
by transitivity of comparison operator.

NOTE: all of the above DOES NOT apply to nlmsg_ok() where ->nlmsg_len is
u32(!), so 3 clauses AND A CAST TO INT are necessary.

Couple conflicts resolved here:

1) In the MACB driver, a bug fix to properly initialize the
   RX tail pointer properly overlapped with some changes
   to support variable sized rings.

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
   overlapping with a reorganization of the driver to support
   ACPI, OF, as well as PCI variants of the chip.

3) In 'net' we had several probe error path bug fixes to the
   stmmac driver, meanwhile a lot of this code was cleaned up
   and reorganized in 'net-next'.

4) The cls_flower classifier obtained a helper function in
   'net-next' called __fl_delete() and this overlapped with
   Daniel Borkamann's bug fix to use RCU for object destruction
   in 'net'.  It also overlapped with Jiri's change to guard
   the rhashtable_remove_fast() call with a check against
   tc_skip_sw().

5) In mlx4, a revert bug fix in 'net' overlapped with some
   unrelated changes in 'net-next'.

6) In geneve, a stale header pointer after pskb_expand_head()
   bug fix in 'net' overlapped with a large reorganization of
   the same code in 'net-next'.  Since the 'net-next' code no
   longer had the bug in question, there was nothing to do
   other than to simply take the 'net-next' hunks.

Qian Zhang (张谦) reported a potential socket buffer overflow in
tipc_msg_build() which is also known as CVE-2016-8632: due to
insufficient checks, a buffer overflow can occur if MTU is too short for
even tipc headers. As anyone can set device MTU in a user/net namespace,
this issue can be abused by a regular user.

As agreed in the discussion on Ben Hutchings' original patch, we should
check the MTU at the moment a bearer is attached rather than for each
processed packet. We also need to repeat the check when bearer MTU is
adjusted to new device MTU. UDP case also needs a check to avoid
overflow when calculating bearer MTU.

Support Armada 37xx SoC (ARMv8 64-bits) in mvneta driver

The Armada 37xx is a new ARMv8 SoC from Marvell using same network
controller as the older Armada 370/38x/XP SoCs. This series adapts the
driver in order to be able to use it on this new SoC. The main changes
are:

- 64-bits support: the first patches allow using the driver on a 64-bit
  architecture.

- MBUS support: the mbus configuration is different on Armada 37xx
  from the older SoCs.

- per cpu interrupt: Armada 37xx do not support per cpu interrupt for
  the NETA IP, the non-per-CPU behavior was added back.

The first patch is an optimization in the rx path in swbm mode.
The second patch remove unnecessary allocation for HWBM.
The first item is solved by patches 4 and 5.
The 2 last items are solved by patch 6.
In patch 7 the dt support is added.

Beside Armada 37xx, this series have been again tested on Armada XP
and Armada 38x (with Hardware Buffer Management and with Software
Buffer Management).

This is the 6th version of the series:
- 1st version:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/469588.html

- 2nd version:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/470476.html

- 3rd version:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/470901.html

- 4th version:

- 5th version:
http://lists.infradead.org/pipermail/linux-arm-kernel/2016-November/471478.html

Changelog:
v5 -> v6:
 - Added Tested-by from  Marcin Wojtas on the series
 - Added Reviewed-by from Jisheng Zhang on patch 3
 - Fix eth1 phy mode for Armada 3720 DB board on patch 7

v4 -> v5:
 - remove unnecessary cast in patch 3

v3 -> v4:
 - Adding new patch: "net: mvneta: do not allocate buffer in rxq init
   with HWBM"

 - Simplify the HWBM case in patch 3 as suggested by Marcin

v2 -> v3:
 - Adding patch 1 "Optimize rx path for small frame"

 - Fix the kbuild error by moving the "phys_addr += pp->rx_offset_correction;"
  line from patch 2 to patch 3 where rx_offset_correction is introduced.

 - Move the memory allocation of the buf_virt_addr of the rxq to be
   called by the probe function in order to avoid a memory leak.

Armada 3700 is a new ARMv8 SoC from Marvell using same network controller
as older Armada 370/38x/XP. There are however some differences that
needed taking into account when adding support for it:

* open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus
  configuration for network controller has to be done on two levels:
  global and per-port. The first one is inherited from the
  bootloader. The latter can be opened in a default way, leaving
  arbitration to the bus controller.  Hence filled mbus_dram_target_info
  structure is not needed

* make per-CPU operation optional - Recent patches adding RSS and XPS
  support for Armada 38x/XP enabled per-CPU operation of the controller
  by default. Contrary to older SoC's Armada 3700 SoC's network
  controller is not capable of per-CPU processing due to interrupt lines'
  connectivity.  This patch restores non-per-CPU operation, which is now
  optional and depends on neta_armada3700 flag value in mvneta_port
  structure. In order not to complicate the code, separate interrupt
  subroutine is implemented.

For now, on the Armada 3700, RSS is disabled as the current
implementation depend on the per cpu interrupts.

Until now the virtual address of the received buffer were stored in the
cookie field of the rx descriptor. However, this field is 32-bits only
which prevents to use the driver on a 64-bits architecture.

With this patch the virtual address is stored in an array not shared with
the hardware (no more need to use the DMA API). Thanks to this, it is
possible to use cache contrary to the access of the rx descriptor member.

The change is done in the swbm path only because the hwbm uses the cookie
field, this also means that currently the hwbm is not usable in 64-bits.
