The MIPI DSI output on Tegra SoCs requires some external logic to
calibrate the MIPI pads before a video signal can be transmitted. This
MIPI calibration logic requires to be powered on while the MIPI pads are
being used, which is currently done as part of the DSI driver's probe
implementation.
This is suboptimal because it will leave the MIPI calibration logic
powered up even if the DSI output is never used.
On Tegra114 and earlier this behaviour also causes the driver to hang
while trying to power up the MIPI calibration logic because the power
partition that contains the MIPI calibration logic will be powered on
by the display controller at output pipeline configuration time. Thus
the power up sequence for the MIPI calibration logic happens before
it's power partition is guaranteed to be enabled.
Fix this by splitting up the API into a request/free pair of functions
that manage the runtime dependency between the DSI and the calibration
modules (no registers are accessed) and a set of enable, calibrate and
disable functions that program the MIPI calibration logic at points in
time where the power partition is really enabled.
While at it, make sure that the runtime power management also works in
ganged mode, which is currently also broken.

Currently, very few RNG drivers support single byte reads using the
->read() interface. Of the 14 drivers in drivers/char/hw_random that
support this interface only three of these actually support max == 1.
The other behaviours vary between return 0, return 2, return 4 and return
-EIO).
This is not a problem in practice because the core hw_random code never
performs a read shorter than 16 bytes. The documentation for this function
already contrains the alignment of the buffer pointer, so let's also
guarantee that the buffer is at least as large as its alignment.
This constraint is intended to be the weakest guarantee neccessary to
allow driver writers to safely simplify their code.

When function graph tracing is enabled for a function, ftrace modifies
the stack by replacing the original return address with the address of a
hook function (return_to_handler).
Stack unwinders need a way to get the original return address. Add an
arch-independent helper function for that named ftrace_graph_ret_addr().
This adds two variations of the function: one depends on
HAVE_FUNCTION_GRAPH_RET_ADDR_PTR, and the other relies on an index state
variable.
The former is recommended because, in some cases, the latter can cause
problems when the unwinder skips stack frames. It can get out of sync
with the ret_stack index and wrong addresses can be reported for the
stack trace.
Once all arches have been ported to use
HAVE_FUNCTION_GRAPH_RET_ADDR_PTR, we can get rid of the distinction.

Storing this value will help prevent unwinders from getting out of sync
with the function graph tracer ret_stack. Now instead of needing a
stateful iterator, they can compare the return address pointer to find
the right ret_stack entry.
Note that an array of 50 ftrace_ret_stack structs is allocated for every
task. So when an arch implements this, it will add either 200 or 400
bytes of memory usage per task (depending on whether it's a 32-bit or
64-bit platform).

First round of IIO fixes for the 4.8 cycle.
This is somewhat of a bumper set due to my unavailabilty earlier in the
month. The only slightly unusual ones are the dts updates for the
rockchip adc reset. The fix in the driver only makes sense with these
and the rockchip maintainer is happy with them going through IIO to
reach mainline.
Core stuff
* Fix an issue with a blocking op when !TASK_RUNNING. This been there
a while and snuck in with seemingly minor additions to some core
code paths.
* Tools
- generic_buffer failed to initialize the channel array pointer thus
in the case of no channels blows up trying to free a random memory
address.
* sw-trigger:
- Fix config group initialization when configfs is built as a module.
Drivers
* ad5933
- Fix an incorrect overwrite of an error value.
* ad799x
- A missed assignment of the update_scan_mode callback means buffered mode
doesn't work on the ad7991, ad7995 or ad7999.
* ads1015
- wrong pointer returned from i2c_get_clientdata (missmatch of assumptions)
* am2315
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
- missing buffer selects in Kconfig
* am335x adc
- Protect fifo1 from concurrent access.
- Increase timeout waiting for ADC to be long enough in all cases.
* as3935
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
* at91
- Fix reading of channel 3.
* atlas-ph-sensor
- Typo means that the scale of electrical conductivity readings is way off.
* bma220
- Timestamps are reported, but never actually acquired from anywhere
(so always 0)
- Missing buffer selects in Kconfig
* bmp280
- pass the write pointer to PTR_ERR (i.e. the one that was just checked
with IS_ERR).
- suspend /resume crash due to wrong assumption about what dev_get_drvdata
would return.
* hdc100x
- It superficially appeared that smbus_read_byte commands would allow
reading of the outputs in two goes. In reality it doesn't work, but
instead returns the same for the upper and lower bytes (nice catch from
Alison!)
* kxsd9
- Fix raw read return value to ensure it actually reports the value rather
than a blank string.
* max44000
- Missing buffer selects in Kconfig
* rockchip_saradc
- Add use of reset controller to enforce a clean state of the ADC.
Some bootloaders can leave it in an 'intersting' state and effectively
frozen without this. A couple of associated dts updates.
* stk8ba50
- Missing buffer selects in Kconfig
* stx104
- Fix a possible race due to use of devm_iio_device_register when there
was other stuff in the remove function.

Multi-channel clients split between several drivers need a way to close
individual channels, as these drivers might be removed individually.
With this in place the responsibility of closing additionally opened
channels to the client as well only concerning smd about the primary
channel.
With this approach we will only trigger removal of SMD devices based on
the state of the primary channel, however we get in sync with how rpmsg

From Hadar and Ilya, added the needed hardware bits and infrastructure for

Modern VFs can't run on old non-compatible as the fastpath HSI is
slightly changed - but as the HSI is actually very close [basically,
a single bit whose meaning flipped] this can be supported with small
modifications.
The major differences would be in:

The TOROUT_STRING() macro does not insert a space between the flag and
the message. In contrast, other similar torture-test dmesg messages
consistently supply a single space character. This difference makes the
output hard to read and to mechanically parse. This commit therefore
adds a space character between flag and message in TOROUT_STRING() output.

The cec-funcs.h header was missing support for these three vendor-specific messages:
CEC_MSG_VENDOR_COMMAND
CEC_MSG_VENDOR_COMMAND_WITH_ID
CEC_MSG_VENDOR_REMOTE_BUTTON_DOWN
Add wrappers for these messages.
I originally postponed adding these wrappers due to the fact that the argument is
just a byte array which cec-ctl couldn't handle at the time, and then I just forgot
to add them once the CEC framework was finalized.
It wasn't until an attempt to transmit a vendor specific command was made that I
realized that these wrappers were missing.

Currently if none of the requested logical addresses can be claimed, the
framework will fall back to the Unregistered logical address.
Add a flag to enable this explicitly. By default it will just go back to
the unconfigured state.
Usually Unregistered is not something you want since the functionality is
very limited. Unless the application has support for this, it will fail
to work correctly. So require that the application explicitly requests
this.

Up to now, RCU has assumed that the CPU-online process makes it from
CPU_UP_PREPARE to set_cpu_online() within one jiffy. Given the recent
rise of virtualized environments, this assumption is very clearly
obsolete. Failing to meet this deadline can result in RCU paying
attention to an incoming CPU for one jiffy, then ignoring it until the
grace period following the one in which that CPU sets itself online.
This situation might prove to be fatally disappointing to any RCU
read-side critical sections that had the misfortune to execute during
the time in which RCU was ignoring the slow-to-come-online CPU.
This commit therefore updates RCU's internal CPU state-tracking
information at notify_cpu_starting() time, thus providing RCU with
an exact transition of the CPU's state from offline to online.
Note that this means that incoming CPUs must not use RCU read-side
critical section (other than those of SRCU) until notify_cpu_starting()
time. Note also that the CPU_STARTING notifiers -are- allowed to use
RCU read-side critical sections. (Of course, CPU-hotplug notifiers are
rapidly becoming obsolete, so you need to act fast!)
If a given architecture or CPU family needs to use RCU read-side
critical sections earlier, the call to rcu_cpu_starting() from
notify_cpu_starting() will need to be architecture-specific, with
architectures that need early use being required to hand-place
the call to rcu_cpu_starting() at some point preceding the call to
notify_cpu_starting().

Now that open delay and sample delay for each channel is configurable
via DT, the default IDLE_TIMEOUT value is not enough as this is

This new firmware for the qed* adpaters fixes several issues:
- Better blocking of malicious VFs.
- After FLR, Tx-switching [internal routing] of packets might
be incorrect.
- Deletion of unicast MAC filters would sometime have side-effect
of corrupting the MAC filters configred for a device.
It also contains fixes for future qed* drivers that *hopefully* would be
sent for review in the near future.
In addition, it would allow driver some new functionality, including:
- Allowing PF/VF driver compaitibility with old drivers [running
pre-8.10.5.0 firmware].
- Better debug facilities.
This would also bump the qed* driver versions to 8.10.9.20.

The commit 8f6fd83c6c5ec66a4a70c728535ddcdfef4f3697 ("rhashtable:
accept GFP flags in rhashtable_walk_init") added a GFP flag argument
to rhashtable_walk_init because some users wish to use the walker
in an unsleepable context.
In fact we don't need to allocate memory in rhashtable_walk_init
at all. The walker is always paired with an iterator so we could
just stash ourselves there.
This patch does that by introducing a new enter function to replace
the existing init function. This way we don't have to churn all
the existing users again.

This work adds a bpf_skb_change_tail() helper for tc BPF programs. The
basic idea is to expand or shrink the skb in a controlled manner. The
eBPF program can then rewrite the rest via helpers like bpf_skb_store_bytes(),
bpf_lX_csum_replace() and others rather than passing a raw buffer for
writing here.
bpf_skb_change_tail() is really a slow path helper and intended for
replies with f.e. ICMP control messages. Concept is similar to other
helpers like bpf_skb_change_proto() helper to keep the helper without
protocol specifics and let the BPF program mangle the remaining parts.
A flags field has been added and is reserved for now should we extend
the helper in future.

BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can
be found in two packages (versions): BCM53573 and BCM47189. It shares
some code with the Northstar family, but also requires some new quirks.
First of all there can be up to 2 Ethernet cores on this SoC. If that is
the case, they are connected to two different switch ports allowing some
more complex/optimized setups. It seems the second unit doesn't come
fully configured and requires some IRQ quirk.
Other than that only the first core is connected to the PHY. For the
second one we have to register fixed PHY (similarly to the Northstar),
otherwise generic PHY driver would get some invalid info.
This has been successfully tested on Tenda AC9 (BCM47189B0).

Add vlan priority check to the flow dissector by adding new flow
dissector struct, flow_dissector_key_vlan which includes vlan tag
fields.
vlan_id and flow_label fields were under the same struct
(flow_dissector_key_tags). It was a convenient setting since struct
flow_dissector_key_tags is used by struct flow_keys and by setting
vlan_id and flow_label under the same struct, we get precisely 24 or 48
bytes in flow_keys from flow_dissector_key_basic.
Now, when adding vlan priority support, the code will be cleaner if
flow_label and vlan tag won't be under the same struct anymore.

The following patchset contains Netfilter updates for your net tree,
they are:
1) Dump only conntrack that belong to this namespace via /proc file.
This is some fallout from the conversion to single conntrack table

2) Missing MODULE_ALIAS_NF_LOGGER() for the ARP family that prevents
module autoloading, also from Liping Zhang.
3) Report overquota event to the right netnamespace, again from Liping.
4) Fix tproxy listener sk refcount that leads to crash, from
Eric Dumazet.
5) Fix racy refcounting on object deletion from nfnetlink and rule
removal both for nfacct and cttimeout, from Liping Zhang.
