additional framework work for dynamic topologies (though we *still*
don't appear to have a stable ABI for the topology code, it's probably
worth considering if this will ever happen...). Otherwise the work has
almost all been in the drivers:
- HDMI support for Sky Lake, along with other fixes and enhancements
for the Intel drivers.
- Lots of improvements to the Renesas drivers.
- Capture support for Qualcomm drivers.
- Support for TI DaVinci DRA7xxx devices.
- New machine drivers for Freescale systems with Cirrus CODECs,
Mediatek systems with RT5650 CODECs.
- New CPU drivers for Allwinner S/PDIF controllers
- New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.

ASoC: Updates for v4.6
The main thing in terms of the core this time around has been some
additional framework work for dynamic topologies (though we *still*
don't appear to have a stable ABI for the topology code, it's probably
worth considering if this will ever happen...). Otherwise the work has

- New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.
Freescale updates from Scott:
"Highlights include 8xx optimizations, 32-bit checksum optimizations,
86xx consolidation, e5500/e6500 cpu hotplug, more fman and other dt
bits, and minor fixes/cleanup."
When a USB LED device is unplugged the remove call chain calls
led_classdev_unregister which tries to switch the LED off.
As the device has been removed already this results in a ENODEV
error message in dmesg.
Avoid this error message by ignoring ENODEV in calls from
led_classdev_unregister if the LED device is flagged as pluggable.
Therefore a new flag LED_HW_PLUGGABLE was introduced which should be set by
all LED drivers handling pluggable LED devices (mainly USB LED devices).

This patch updates csum_ipv6_magic so that it correctly recognizes that
protocol is a unsigned 8 bit value.
This will allow us to better understand what limitations may or may not be
present in how we handle the data. For example there are a number of
places that call htonl on the protocol value. This is likely not necessary
and can be replaced with a multiplication by ntohl(1) which will be
converted to a shift by the compiler.

This patch updates all instances of csum_tcpudp_magic and
csum_tcpudp_nofold to reflect the types that are usually used as the source
inputs. For example the protocol field is populated based on nexthdr which
is actually an unsigned 8 bit value. The length is usually populated based
on skb->len which is an unsigned integer.
This addresses an issue in which the IPv6 function csum_ipv6_magic was
generating a checksum using the full 32b of skb->len while
csum_tcpudp_magic was only using the lower 16 bits. As a result we could
run into issues when attempting to adjust the checksum as there was no
protocol agnostic way to update it.
With this change the value is still truncated as many architectures use
"(len + proto) << 8", however this truncation only occurs for values
greater than 16776960 in length and as such is unlikely to occur as we stop
the inner headers at ~64K in size.
I did have to make a few minor changes in the arm, mn10300, nios2, and
score versions of the function in order to support these changes as they
were either using things such as an OR to combine the protocol and length,
or were using ntohs to convert the length which would have truncated the
value.
I also updated a few spots in terms of whitespace and type differences for
the addresses. Most of this was just to make sure all of the definitions
were in sync going forward.

Currently sctp_sendmsg() triggers some calls that will allocate memory
with GFP_ATOMIC even when not necessary. In the case of
sctp_packet_transmit it will allocate a linear skb that will be used to
construct the packet and this may cause sends to fail due to ENOMEM more
often than anticipated specially with big MTUs.
This patch thus allows it to inherit gfp flags from upper calls so that
it can use GFP_KERNEL if it was triggered by a sctp_sendmsg call or
similar. All others, like retransmits or flushes started from BH, are
still allocated using GFP_ATOMIC.
In netperf tests this didn't result in any performance drawbacks when
memory is not too fragmented and made it trigger ENOMEM way less often.

The canonical netif header (in the Xen source repo) and the Linux variant
have diverged significantly. Recently much documentation has been added to
the canonical header which is highly useful for developers making
modifications to either xen-netfront or xen-netback. This patch therefore
re-imports the canonical header in its entirity.
To maintain compatibility and some style consistency with the old Linux
variant, the header was stripped of its emacs boilerplate, and
post-processed and copied into place with the following commands:

The code for csum_block_add was doing a funky byteswap to swap the even and
odd bytes of the checksum if the offset was odd. Instead of doing this we
can save ourselves some trouble and just shift by 8 as this should have the
same effect in terms of the final checksum value and only requires one
instruction.
In addition we can update csum_block_sub to just use csum_block_add with a
inverse value for csum2. This way we follow the same code path as
csum_block_add without having to duplicate it.

This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places. They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.
The other changes are:
- A fix for Qualcomm devices to work on big endian systems. The
original change is actually correct but triggered a bug in regmap
which is too invasive to fix for this cycle and can be worked around
by just letting regmap pick the default.
- A fix for the Samsung I2S driver locking which wasn't using IRQ safe
spinlocks when it needed to.
- A fix for the new Intel Sky Lake driver forgetting that C pointer
arithmetic takes the type of the pointer into consideration.
- A revert of a change to the FSL SSI driver that broke some systems.
- A fix for the cleanup path of the wm9713 driver.
- A fix for some incorrect register definitions in the ADAU17x1 driver
that caused misclocking in some configurations.
- A fix for the tracepoints for jack detection to avoid using an
internal field of the core jack structure which is no longer present
in all configurations.
- A fix for another of the new Intel drivers which tried to write to a
string literal.

Now we again will revive it as DRM_EXYNOS_GEM_MAP because of render

1. Split out Exynos PMU driver implementation from arm/mach-exynos
to the drivers/soc/samsung which will allow re-use of it on ARM64.
2. Use generic DT cpufreq driver on Exynos542x/5800.
3. Minor cleanups.

For !BIO_CLONED bio, we can use .bi_vcnt safely, but it
doesn't mean we can just simply return .bi_io_vec[.bi_vcnt - 1]
because the start postion may have been moved in the middle of
the bvec, such as splitting in the middle of bvec.

It is often the case that the driver wants to be sure a device stays
in direct mode while it is executing a task or series of tasks. To
accomplish this today, the driver performs this sequence: 1) take the
device state lock, 2) verify it is not in a buffered mode, 3) execute
some tasks, and 4) release that lock.
This patch introduces a pair of helper functions that simplify these
steps and make it more semantically expressive.
iio_device_claim_direct_mode()
If the device is not in any buffered mode it is guaranteed
to stay that way until iio_release_direct_mode() is called.
iio_device_release_direct_mode()
Release the claim. Device is no longer guaranteed to stay
in direct mode.

[media] media-device: map new functions into old types for legacy API
This patch extends bpf_tunnel_key with a tunnel_label member, that maps
to ip_tunnel_key's label so underlying backends like vxlan and geneve
can propagate the label to udp_tunnel6_xmit_skb(), where it's being set
in the IPv6 header. It allows for having 20 more bits to encode/decode
flow related meta information programmatically. Tested with vxlan and
geneve.

This work adds support for setting the IPv6 flow label for geneve per
device and through collect metadata (ip_tunnel_key) frontends. Also here,
the geneve dst cache does not need any special considerations, for the
cases where caches can be used, the label is static per cache.

This patch extends udp_tunnel6_xmit_skb() to pass in the IPv6 flow label
from call sites. Currently, there's no such option and it's always set to
zero when writing ip6_flow_hdr(). Add a label member to ip_tunnel_key, so
that flow-based tunnels via collect metadata frontends can make use of it.
vxlan and geneve will be converted to add flow label support separately.

This fixes a regression in the bridge ageing time caused by:
commit c62987bbd8 ("bridge: push bridge setting ageing_time down to switchdev")
There are users of Linux bridge which use the feature that if ageing time
is set to 0 it causes entries to never expire. See:
https://www.linuxfoundation.org/collaborate/workgroups/networking/bridge
For a pure software bridge, it is unnecessary for the code to have
arbitrary restrictions on what values are allowable.
