Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next 

Resolve conflict between commit 264640fc2c ("ipv6: distinguish frag
queues by device for multicast and link-local packets") from the net
tree and commit 029f7f3b87 ("netfilter: ipv6: nf_defrag: avoid/free
clone operations") from the nf-next tree.

disable all padding.

Contact: Bjørn Mork <bjorn@mork.no>
Description:
Boolean attribute showing the status of the "NDP to
end" quirk. Defaults to 'N', except for devices
already known to need it enabled.
The "NDP to end" quirk makes the driver place the NDP
(the packet index table) after the payload. The NCM
specification does not mandate this, but some devices
are known to be more restrictive. Write 'Y' to this
attribute for temporary testing of a suspect device
failing to work with the default driver settings.
A device entry should be added to the driver if this
quirk is found to be required.

What: /sys/class/net/<iface>/qmi/raw_ip
Date: Dec 2015
KernelVersion: 4.4
Contact: Bjørn Mork <bjorn@mork.no>
Description:
Boolean. Default: 'N'
Set this to 'Y' to change the network device link
framing from '802.3' to 'raw-ip'.
The netdev will change to reflect the link framing
mode. The netdev is an ordinary ethernet device in
'802.3' mode, and the driver expects to exchange
frames with an ethernet header over the USB link. The
netdev is a headerless p-t-p device in 'raw-ip' mode,
and the driver expects to echange IPv4 or IPv6 packets
without any L2 header over the USB link.
Userspace is in full control of firmware configuration
through the delegation of the QMI protocol. Userspace
is responsible for coordination of driver and firmware
link framing mode, changing this setting to 'Y' if the
firmware is configured for 'raw-ip' mode.

The device tree documentation for the keystone machines are located at
Documentation/devicetree/bindings/arm/keystone/keystone.txt
Known issues & workaround
-------------------------
Some of the device drivers used on keystone are re-used from that from
DaVinci and other TI SoCs. These device drivers may use clock APIs directly.
Some of the keystone specific drivers such as netcp uses run time power
management API instead to enable clock. As this API has limitations on
keystone, following workaround is needed to boot Linux.
Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise
clock frameworks will try to disable clocks that are unused and disable
the hardware. This is because netcp related power domain and clock
domains are enabled in u-boot as run time power management API currently
doesn't enable clocks for netcp due to a limitation. This workaround is
expected to be removed in the future when proper API support becomes
available. Until then, this work around is needed.

bool "Cortex-A57: 834220: Stage 2 translation fault might be incorrectly reported in presence of a Stage 1 fault"
depends on KVM
default y
help
This option adds an alternative code sequence to work around ARM
erratum 834220 on Cortex-A57 parts up to r1p2.
Affected Cortex-A57 parts might report a Stage 2 translation
fault as the result of a Stage 1 fault for load crossing a
page boundary when there is a permission or device memory
alignment fault at Stage 1 and a translation fault at Stage 2.
The workaround is to verify that the Stage 1 translation
doesn't generate a fault before handling the Stage 2 fault.
Please note that this does not necessarily enable the workaround,
as it depends on the alternative framework, which will only patch
the kernel if an affected CPU is detected.
If unsure, say Y.
