cc8889ae82 doc: document MSG_ZEROCOPY
Documentation for this feature was missing from the patchset.
Copied a lot from the netdev 2.1 paper, addressing some small
interface changes since then.

Changes
  v1 -> v2
    - change email discussion URL format
    - clarify that u32 counter is per-syscall, unsigned and
      wraps after UINT_MAX calls
    - describe errno on send failure specific to MSG_ZEROCOPY
    - a few very minor rewordings

86c0f046a8 Documentation/sphinx: fix kernel-doc decode for non-utf-8 locale
On python3, Popen() universal_newlines=True converts the subprocess
stdout to unicode text using a codec based on user preferences. Given
LANG indicating ascii and utf-8 stdout from the subprocess, you'd get:

WARNING: kernel-doc '../scripts/kernel-doc -rst -enable-lineno
../drivers/media/dvb-core/demux.h' processing failed with: 'ascii' codec can't
decode byte 0xe2 in position 6368: ordinal not in range(128)

Fix this by dropping universal_newlines=True and replacing the implicit
LANG specific decode with an explicit utf-8 decode. This also gets rid
of the annoying conditional code for python 2 vs. 3.

Fixes: ba3501859354 ("Documentation/sphinx: fix kernel-doc extension on python3")

097578ec20 staging: typec: fusb302: Get max snk mv/ma/mw from device-properties
This is board specific info so it should come from board config, such
as devicetree.

I've chosen to prefix these with "fcs," treating them as fusb302 driver
specific for now. We may want to revisit this and replace these with
properties which are part of a (to be written) generic type-c controller
devicetree binding.

Since this commit adds new dt-properties it also adds devicetree-bindings
documentation (which so far was absent for the fusb302 driver).

fd100dab63 irqchip/ls-scfg-msi: Add LS1043a v1.1 MSI support
A MSI controller of LS1043a v1.0 only includes one MSIR and
is assigned one GIC interrupt. In order to support affinity,
LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts.
But the MSIR has the different offset and only supports 8 MSIs.
The bits between variable bit_start and bit_end in structure
ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and
msir_base are added to describe the difference of MSI between
LS1043a v1.1 and other SoCs.

6606bc9dee pinctrl: Add sleep related state to indicate sleep related configs
In some scenarios, we should set some pins as input/output/pullup/pulldown
when the specified system goes into deep sleep mode, then when the system
goes into deep sleep mode, these pins will be set automatically by hardware.

That means some pins are not controlled by any specific driver in the OS, but
need to be controlled when entering sleep mode. Thus we introduce one sleep
state config into pinconf-generic for users to configure.

eaa72dc474 neigh: increase queue_len_bytes to match wmem_default
Florian reported UDP xmit drops that could be root caused to the
too small neigh limit.

Current limit is 64 KB, meaning that even a single UDP socket would hit
it, since its default sk_sndbuf comes from net.core.wmem_default
(~212992 bytes on 64bit arches).

Once ARP/ND resolution is in progress, we should allow a little more
packets to be queued, at least for one producer.

Once neigh arp_queue is filled, a rogue socket should hit its sk_sndbuf
limit and either block in sendmsg() or return -EAGAIN.

c038a58ccf rxrpc: Allow failed client calls to be retried
Allow a client call that failed on network error to be retried, provided
that the Tx queue still holds DATA packet 1.  This allows an operation to
be submitted to another server or another address for the same server
without having to repackage and re-encrypt the data so far processed.

Two new functions are provided:

 (1) rxrpc_kernel_check_call() - This is used to find out the completion
     state of a call to guess whether it can be retried and whether it
     should be retried.

 (2) rxrpc_kernel_retry_call() - Disconnect the call from its current
     connection, reset the state and submit it as a new client call to a
     new address.  The new address need not match the previous address.

A call may be retried even if all the data hasn't been loaded into it yet;
a partially constructed will be retained at the same point it was at when
an error condition was detected.  msg_data_left() can be used to find out
how much data was packaged before the error occurred.

Add a callback to rxrpc_kernel_send_data() so that a kernel service can get
a notification that the AF_RXRPC call has transitioned out the Tx phase and
is now waiting for a reply or a final ACK.

This is called from AF_RXRPC with the call state lock held so the
notification is guaranteed to come before any reply is passed back.

Further, modify the AFS filesystem to make use of this so that we don't have
to change the afs_call state before sending the last bit of data.

0c0b6b7bc4 PM: docs: Describe high-level PM strategies and sleep states
Reorganize the power management part of admin-guide by adding a
description of major power management strategies supported by the
kernel (system-wide and working-state power management) to it and
dividing the rest of the material into the system-wide PM and
working-state PM chapters.

On top of that, add a description of system sleep states to the
system-wide PM chapter.

9f57ed095f Update extcon for 4.14
Detailed description for this pull request:
 1. Add new 'extcon-usbc-cros-ec.c' driver
 - ChromeOS Embedded Controller extcon driver supports
   the detection of the Display Port (EXTCON_DISP_DP)
   through USB C-type and contol it.
 
 2. Update extcon core
 - Modify the description for both functions and structures
   in order to improve the readability and give the more correct
   guide about the role of functions because there are different
   explanation even if the same arguments.
 
 - Keep the indentation with tab instead of space
 
 - Remove the following deprecated extcon API. The deprecated API
   are exchanged on all of linux tree.
   : extcon_get_cable_state_() -> extcon_get_state()
   : extcon_set_cable_state_() -> extcon_set_state_sync()
 
 3. Include the two immutable branch as following:
 - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver
   because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory.
 - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API
   because the usb/phy driver usese the deprecated extcon API.
   So, this immutable branch alters the extcon API and then
   remove them from extcon.
 
 4. Fix minor issue of extcon driver
 - Fix the MHL detection on extcon-max77693.c
 - Convert to using %pOF instead of full_name on extcon.c
 - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

e545f0d8a5 thunderbolt: Allow clearing the key
If secure authentication of a devices fails, either because the device
already has another key uploaded, or there is some other error sending
challenge to the device, and the user only wants to approve the device
just once (without a new key being uploaded to the device) the current
implementation does not allow this because the key cannot be cleared
once set even if we allow it to be changed.

Make this scenario possible and allow clearing the key by writing
empty string to the key sysfs file.

1c8859848d coresight replicator: Cleanup programmable replicator naming
The Linux coresight drivers define the programmable ATB replicator as
Qualcomm replicator, while this is designed by ARM. This can cause
confusion to a user selecting the driver. Cleanup all references to
make it explicitly clear. This patch :

 1) Replace the compatible string for the replicator :
      qcom,coresight-replicator1x => arm,coresight-dynamic-replicator
 2) Changes the Kconfig symbol (since this is not part of any defconfigs)
     CORESIGHT_QCOM_REPLICATOR => CORESIGHT_DYNAMIC_REPLICATOR
 3) Improves the help message in the Kconfig.
 4) Changes the name of the driver and the file :
      coresight-replicator-qcom => coresight-dynamic-replicator
