net/ipv6: Correct PIM6 mrt_lock handling
In the IPv6 multicast routing code the mrt_lock was not being released
correctly in the MFC iterator, as a result adding or deleting a MIF would
cause a hang because the mrt_lock could not be acquired.
This fix is a copy of the code for the IPv4 case and ensures that the lock
is released correctly.

couple of sctp fixes for
0ca50d12fe46
These are two fixes for sctp after my patch on
0ca50d12fe46 ("sctp: fix

The first, fix a dst leak on those it decided to skip.
The second, adds the fallback on src selection that Vlad had asked
about. Unfortunatelly a lot of ipvs setups relies on the old behavior
and I don't see a better fix for it.

sctp: add routing output fallback
Commit
0ca50d12fe46 added a restriction that the address must belong to
the output interface, so that sctp will use the right interface even
when using secondary addresses.
But it breaks IPVS setups, on which people is used to attach VIP
addresses to loopback interface on real servers. It's preferred to
attach to the interface actually in use, but it's a very common setup
and that used to work.
This patch then saves the first routing good result, even if it would be
going out through an interface that doesn't have that address. If no
better hit found, it's then used. This effectively restores the original
behavior if no better interface could be found.

Therefore, split the more generic parts into a common header under

xen-netback: add support for multicast control
Xen's PV network protocol includes messages to add/remove ethernet
multicast addresses to/from a filter list in the backend. This allows
the frontend to request the backend only forward multicast packets
which are of interest thus preventing unnecessary noise on the shared
ring.
The canonical netif header in git://xenbits.xen.org/xen.git specifies
the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal
necessary changes have been pulled into include/xen/interface/io/netif.h.
To prevent the frontend from extending the multicast filter list
arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries.
This limit is not specified by the protocol and so may change in future.
If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD
sent by the frontend will be failed with NETIF_RSP_ERROR.

Intel Wired LAN Driver Updates 2015-09-01
This series contains updates to i40e, ixgbe and ixgbevf.
Anjali fixes a bug in i40e where the port is not receiving multicast or VLAN
tagged packets in promiscuous mode. Which can occur when a software bridge
is created on top of the device.
Don adds support in ixgbe that indicates the presence of management firmware.
Added support for entering low power link up state on devices that support
it when the device is closing or suspending. Updated the driver to report
unknown bus speed and width since IOSF does not report a PCIe bus speed or
width for X550 devices. Also added the new bus type for integrated I/O
interface (IOSF). Cleaned up of redundant code in ixgbe.
Mark adds support for UDP-encapsulation transmit checksum and for VXLAN
receive offloads. Introduces a helper function to do the register access
and processing to avoid needless PHY access on copper PHYs. Added support
for reporting 2.5G link speed. Fixed warnings resulting from redundant
initializations of the get_bus_info field.
Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc
for allocation of one thing.
Tom Barbette adds support for ethtool to change the rxfh indirection table
and/or key using ethtool interface.
Emil resolves an issue where users were not able to dynamically set number
of queues for 82598 via ethtool -L.
Alex Williamson removes bimodal SR-IOV disabling behavior since it is
confusing to users and results in a state where the PF is broken for other
uses unless the user sets sriov_numvfs to zero prior to unbinding the
device.

ixgbe: Remove bimodal SR-IOV disabling
When unbinding an SR-IOV device with VFs configured from ixgbe, the
driver behaves in one of two ways. If max_vfs was specified, the
SR-IOV state is disabled, removing the VFs. The occurs regardless of
whether the VF count was later modified through sysfs. If however
max_vfs is zero, such as by not specifying the module parameter, the
VFs persist after the PF is unbound from ixgbe. If the PF is then
bound to vfio-pci to be assigned to a VM, the PF is non-functional.
>From the comment, commit
da36b64736cf ("ixgbe: Implement PCI SR-IOV
sysfs callback operation") clearly intended this alternate behavior,
but probably didn't realize the PF doesn't work in this mode.
This bimodal behavior is confusing to users and results in a state
where the PF is broken for other uses unless the user sets
sriov_numvfs to zero prior to unbinding the device. Remove this
behavior so that VFs are removed and the PF is functional for other
uses after unbind, regardless of the way VFs are enabled.

i40e: Set defport behavior for the Main VSI when in promiscuous mode
This fixes bugs where the port is not receiving multicast or VLAN tagged
packets when in promiscuous mode. This can occur when a SW bridge is
created on top of the device.
This also fixes issues where the promiscuous behavior setting was not
being preserved across a reset caused by features being enabled or
disabled.
We are using defport instead of doing a true promiscuous mode because we do
not need to receive the SRIOV or VMDq VSI directed traffic which would suck
up bandwidth and is really not intended for the SW bridge.
In addition, with defport we get VLAN promiscuous behavior which is not
possible from the VSI level promiscuous setting.

It also straightens out the handling of clone flags related to user

Finally, this fixes a minor regression caused by the introduction of
sysfs_create_mount_point, which broke someone's in house application,

====================
flow_dissector: Paramterize dissection and other features
This patch set adds some new capabilities to flow_dissector:
- Add flags to flow dissector functions to control dissection
- Flag to stop dissection when L3 header is seen (don't
dissect L4)
- Flag to stop dissection when encapsulation is detected
- Flag to parse first fragment of fragmented packet. This
may provide L4 ports
- Added new reporting in key_control
- Packet is a fragment
- Packet is a first fragment
- Packet has encapsulation
Also:
- Make __skb_set_sw_hash a general function
- Create functions to get a flow hash based on flowi4 or flowi6
structures without an reference to an skbuff
- Ignore flow dissector return value from ___skb_get_hash. Just
use whatever key fields are found to make a hash
Tested:
Ran 200 netperf TCP_RR instances for IPv6 and IPv4. Did not see any
regression. Ran UDP_RR with 10000 byte request and response size
for IPv4 and IPv6, no regression observed however I did see better
performance with IPv6 flow labels due to use of flow labels for L4
hash.

The problem is that mdiobus_unregister() deletes the bus device before
unregistering the phy devices on the bus. This wasn't a problem before
because the phys were not children of the bus:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0
But now that they are:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03
when mdiobus_unregister deletes the bus device, the phy subdirs are
removed from sysfs also. So when the phys are unregistered afterward,
we get the warning. This patch changes the order so that phys are
unregistered before the bus device is deleted.

"Ladies and gentlemen, we proudly announce to you the latest branch of
ARM device tree contents for the mainline kernel. Come and see, come
and see!
No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported
hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
UniPhier hardware!
For those of you feeling less adventurous, added hardware support on
platforms such as TI DM814x and Gumstix Overo platforms might be more
of your liking.
We've got something for everyone here!
Ahem. Cough. So, anyway...
This is the usual large batch of DT updates. Lots and lots of smaller
changes, some of the larger ones to point out are:
- Rockchip veyron (Chromebook) support, as well as several other new boards
- DRM support on Atmel AT91SAM9N12EK
- USB additions on some Allwinner platforms
- Mediatek MT6580 support
- Freescale i.MX6UL support
- cleanups for Renesas shmobile platforms
- lots of added devices on LPC18xx
- lots of added devices and boards on UniPhier
There's also some dependent code added here, in particular some
branches that are primarily merged through the clock tree"

cpufreq: speedstep-lib: Use monotonic clock
Wall time obtained from do_gettimeofday is susceptible to sudden jumps due to
user setting the time or due to NTP.
Monotonic time is constantly increasing time better suited for comparing two
timestamps.

cpufreq: drop !cpufreq_driver check from cpufreq_parse_governor()
Driver is guaranteed to be present on a call to cpufreq_parse_governor()
and there is no need to check for !cpufreq_driver. Drop it.
