41ecc3d390 Merge branch 'flow-dissector-features'
Tom Herbert says:

====================
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.

6db61d79c1 flow_dissector: Ignore flow dissector return value from ___skb_get_hash
In ___skb_get_hash ignore return value from skb_flow_dissect_flow_keys.
A failure in that function likely means that there was a parse error,
so we may as well use whatever fields were found before the error was
hit.  This is also good because it means we won't keep trying to derive
the hash on subsequent calls to skb_get_hash for the same packet.

823b969395 flow_dissector: Add control/reporting of encapsulation
Add an input flag to flow dissector on rather dissection should stop
when encapsulation is detected (IP/IP or GRE). Also, add a key_control
flag that indicates encapsulation was encountered during the
dissection.

872b1abb1e flow_dissector: Add flag to stop parsing when an IPv6 flow label is seen
Add an input flag to flow dissector on rather dissection should be
stopped when a flow label is encountered. Presumably, the flow label
is derived from a sufficient hash of an inner transport packet so
further dissection is not needed (that is ports are not included in
the flow hash). Using the flow label instead of ports has the additional
benefit that packet fragments should hash to same value as non-fragments
for a flow (assuming that the same flow label is used).

We set this flag by default in for skb_get_hash.

8306b688f1 flow_dissector: Add flag to stop parsing at L3
Add an input flag to flow dissector on rather dissection should be
stopped when an L3 packet is encountered. This would be useful if a
caller just wanted to get IP addresses of the outermost header (e.g.
to do an L3 hash).

a6e544b0a8 flow_dissector: Jump to exit code in __skb_flow_dissect
Instead of returning immediately (on a parsing failure for instance) we

c6cc1ca7f4 flowi: Abstract out functions to get flow hash based on flowi
Create __get_hash_from_flowi6 and __get_hash_from_flowi4 to get the
flow keys and hash based on flowi structures. These are called by
__skb_get_hash_flowi6 and __skb_get_hash_flowi4. Also, created
get_hash_from_flowi6 and get_hash_from_flowi4 which can be called
when just the hash value for a flowi is needed.

b6c6aedcbc phylib: fix device deletion order in mdiobus_unregister()
commit 8b63ec1837 ("phylib: Make PHYs children of their MDIO bus, not
the bus' parent.") uncovered a problem in mdiobus_unregister() which
leads to this warning when I reboot an APM Mustang (arm64) platform:

  [<fffffe00000e3670>] SyS_reboot+0x17c/0x250

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.

8d01b66b4f ARM: SoC 64-bit changes for v4.3
Here's our branch of ARM64 contents for this merge window.
 
 Most of this is DT contents for new SoCs (or those who have seen new
 device support added). Maybe we should stop separating out the arm64
 contents here to avoid the kind of internal conflicts as we got this
 time around, where 32- and 64-bit contents conflicted.
 
 Anyhow, on the actual contents:
 
 New SoCs:
 
 - Broadcom North Star 2 (ns2)
 - Marvell Berlin4CT
 - Mediatek MT6795
 - Rockchip RK3368
 
 In addition, there are enhancements for the following platforms:
 
 - Mediatek MT8173: cpuidle-dt updates, misc other additions
 - ZyncMP: A bunch of devices added to the existing DTSI
 - Qualcomm MSM8916 and APQ8016 updates for USB, etc.
 
 + A handful of other updates for various platforms

Pull ARM DT updates from Olof Johansson:
 "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

102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

c5fc249862 ARM: SoC cleanups for v4.3
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre

'user_policy' caches properties of a policy that are set by userspace.
And these must be updated only if cpufreq core was successful in
updating them based on request from user space.

In store_scaling_governor(), we are updating user_policy.policy and
user_policy.governor even if cpufreq_set_policy() failed. That's
incorrect.

Fix this by updating user_policy.* only if we were successful in
updating the properties.

1453863fb0 cpufreq: mediatek: Add MT8173 cpufreq driver
Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and
2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage
inputs, Vproc and Vsram are supplied by two regulators. For the big
cluster, two regulators come from different PMICs. In this case, when
scaling voltage inputs of the cluster, the voltages of two regulator
inputs need to be controlled by software explicitly under the SoC
specific limitation:

	100mV < Vsram - Vproc < 200mV

which is called 'voltage tracking' mechanism. And when scaling the
frequency of cluster clock input, the input MUX need to be parented to
another "intermediate" stable PLL first and reparented to the original
PLL once the original PLL is stable at the target frequency. This patch
implements those mechanisms to enable CPU DVFS support for Mediatek
MT8173 SoC.
