====================
100GbE Intel Wired LAN Driver Updates 2018-03-26

This patch series adds the ice driver, which will support the Intel(R)
E800 Series of network devices.

This is the first phase in the release of this driver where we implement
basic transmit and receive. The idea behind the multi-phase release is to
aid in code review as well as testing. Subsequent phases will implement
advanced features (like SR-IOV, tunnelling, flow director, QoS, etc.) that
build upon the previous phase(s). Each phase will be submitted as a patch
series.

Suzuki K Poulose ece1397cbc arm64: Add work around for Arm Cortex-A55 Erratum 1024718
Some variants of the Arm Cortex-55 cores (r0p0, r0p1, r1p0) suffer
from an erratum 1024718, which causes incorrect updates when DBM/AP
bits in a page table entry is modified without a break-before-make
sequence. The work around is to skip enabling the hardware DBM feature
on the affected cores. The hardware Access Flag management features
is not affected. There are some other cores suffering from this
errata, which could be added to the midr_list to trigger the work
around.

Ever since commit 3a06c7ac24 ("posix-clocks: Remove interval timer
facility and mmap/fasync callbacks") the possibility of PHC based
posix timers has been removed.  In addition it will probably never
make sense to implement this functionality.

This patch removes the misleading text which seems to suggest that
posix timers for PHC devices will ever be a thing.

Ivan Gorinov 7f2e858408 of/Documentation: Specify local APIC ID in "reg"
Use the "reg" property to specify the processor's local APIC ID instead of
setting it to the CPU node index in Device Tree.

Local APIC ID is assigned by hardware and visible in the APIC ID register.
Some processor models allow APIC ID to be changed by software, but CPUID
instruction executed with %eax = 0x0b always returns the initial ID in %edx.

Local APIC ID does not match the node index in many systems.

Masahiro Yamada 911a91c39c kconfig: rename silentoldconfig to syncconfig
As commit cedd55d49d ("kconfig: Remove silentoldconfig from help
and docs; fix kconfig/conf's help") mentioned, 'silentoldconfig' is a
historical misnomer.  That commit removed it from help and docs since
it is an internal interface.  If so, it should be allowed to rename
it to something more intuitive.  'syncconfig' is the one I came up
with because it updates the .config if necessary, then synchronize
include/generated/autoconf.h and include/config/* with it.

You should not manually invoke 'silentoldcofig'.  Display warning if
used in case existing scripts are doing wrong.

Masahiro Yamada bd0f98eba6 kbuild: remove internally used LDFLAGS_vmlinux from kbuild.txt
Documentation/kbuild/makefiles.txt lists variables used in Makefile
whereas Documentation/kbuild/kbuild.txt describes user assignable
parameters given via environments or the command line.

The top Makefile and arch/*/Makefile accumulate proper linker flags to
LDFLAGS_vmlinux.  So, users can not override it from the command line.
Generally, per-file options are not supposed to be user-assignable.
Remove the misleading entry from kbuild.txt.

If we need a way to append user-specific flags for linking the kernel,
LDFLAGS_KERNEL would be a consistent choice because we already expose
LDFLAGS_MODULE counter-part to users.

Documentation/kbuild/makefiles.txt lists variables used in Makefile
whereas Documentation/kbuild/kbuild.txt describes user assignable
parameters given via environments or the command line.

LDFLAGS_MODULE is a command line interface, so it should be dropped
from makefiles.txt.

Some lines below in this file, it is clearly explained that
KBUILD_LDFLAGS_MODULE is the right one for the internal use:

    KBUILD_LDFLAGS_MODULE   Options for $(LD) when linking modules

        $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options
        used when linking modules. This is often a linker script.
        From commandline LDFLAGS_MODULE shall be used (see kbuild.txt).

Then, kbuild.txt explains LDFLAGS_MODULE, like follows:

    LDFLAGS_MODULE

    Additional options used for $(LD) when linking modules.

Incremental linking is gone, so rename built-in.o to built-in.a, which
is the usual extension for archive files.

This patch does two things, first is a simple search/replace:

git grep -l 'built-in\.o' | xargs sed -i 's/built-in\.o/built-in\.a/g'

The second is to invert nesting of nested text manipulations to avoid
filtering built-in.a out from libs-y2:

-libs-y2 := $(filter-out %.a, $(patsubst %/, %/built-in.a, $(libs-y)))
+libs-y2 := $(patsubst %/, %/built-in.a, $(filter-out %.a, $(libs-y)))

David S. Miller 03fe2debbb Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Fun set of conflict resolutions here...

For the mac80211 stuff, these were fortunately just parallel
adds.  Trivially resolved.

In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.

In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.

The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.

The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:

====================

    Due to bug fixes found by the syzkaller bot and taken into the for-rc
    branch after development for the 4.17 merge window had already started
    being taken into the for-next branch, there were fairly non-trivial
    merge issues that would need to be resolved between the for-rc branch
    and the for-next branch.  This merge resolves those conflicts and
    provides a unified base upon which ongoing development for 4.17 can
    be based.

    Conflicts:
            drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
            (IB/mlx5: Fix cleanup order on unload) added to for-rc and
            commit b5ca15ad7e (IB/mlx5: Add proper representors support)
            add as part of the devel cycle both needed to modify the
            init/de-init functions used by mlx5.  To support the new
            representors, the new functions added by the cleanup patch
            needed to be made non-static, and the init/de-init list
            added by the representors patch needed to be modified to
            match the init/de-init list changes made by the cleanup
            patch.
    Updates:
            drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
            prototypes added by representors patch to reflect new function
            names as changed by cleanup patch

Greg Kroah-Hartman 6d23ee9caa usb: changes for v4.17 merge window
Quite a lot happened in this cycle, with a total of 95 non-merge
 commits. The most interesting parts are listed below:
 
 Synopsys has been adding better support for USB 3.1 to dwc3. The same
 series also sets g_mass_storage's max speed to SSP.
 
 Roger Quadros (TI) added support for dual-role using the OTG block
 available in some dwc3 implementations, this makes sure that AM437x
 can swap roles in runtime.
 
 We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to
 the work of Martin Blumenstingl.
 
 We also have a ton of changes in dwc2 (51% of all changes, in
 fact). The most interesting part there is the support for
 Hibernation (a Synopsys PM feature).
 
 Apart from these, we have our regular set of non-critical fixes all
 over the place.

Mimi Zohar 9e67028e76 ima: fail signature verification based on policy
This patch addresses the fuse privileged mounted filesystems in
environments which are unwilling to accept the risk of trusting the
signature verification and want to always fail safe, but are for example
using a pre-built kernel.

This patch defines a new builtin policy named "fail_securely", which can
be specified on the boot command line as an argument to "ima_policy=".

Matthew Garrett d906c10d8a IMA: Support using new creds in appraisal policy
The existing BPRM_CHECK functionality in IMA validates against the
credentials of the existing process, not any new credentials that the
child process may transition to. Add an additional CREDS_CHECK target
and refactor IMA to pass the appropriate creds structure. In
ima_bprm_check(), check with both the existing process credentials and
the credentials that will be committed when the new process is started.
This will not change behaviour unless the system policy is extended to
include CREDS_CHECK targets - BPRM_CHECK will continue to check the same
credentials that it did previously.

After this patch, an IMA policy rule along the lines of:

measure func=CREDS_CHECK subj_type=unconfined_t

will trigger if a process is executed and runs as unconfined_t, ignoring
the context of the parent process. This is in contrast to:

measure func=BPRM_CHECK subj_type=unconfined_t

which will trigger if the process that calls exec() is already executing
in unconfined_t, ignoring the context that the child process executes
into.

Luis R. Rodriguez 5d42c96e1c firmware: add firmware_request_cache() to help with cache on reboot
Some devices have an optimization in place to enable the firmware to
be retaineed during a system reboot, so after reboot the device can skip
requesting and loading the firmware. This can save up to 1s in load
time. The mt7601u 802.11 device happens to be such a device.

When these devices retain the firmware on a reboot and then suspend
they can miss looking for the firmware on resume. To help with this we
need a way to cache the firmware when such an optimization has taken
place.

Heikki Krogerus fde0aa6c17 usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the
data role for USB connector. With dual-role capable USB
controllers, the controller itself will be the switch, but
on some platforms the USB host and device controllers are
separate IPs and there is a mux between them and the
connector. On those platforms the mux driver will need to
register the switch.

With USB Type-C connectors, the host-to-device relationship
is negotiated over the Configuration Channel (CC). That
means the USB Type-C drivers need to be in control of the
role switch. The class provides a simple API for the USB
Type-C drivers for the control.

For other types of USB connectors (mainly microAB) the class
provides user space control via sysfs attribute file that
can be used to request role swapping from the switch.

Heikki Krogerus bdecb33af3 usb: typec: API for controlling USB Type-C Multiplexers
USB Type-C connectors consist of various muxes and switches
that route the pins on the connector to the right locations.
The USB Type-C drivers need to be able to control the muxes,
as they are the ones that know things like the cable plug
orientation, and the current mode that was negotiated with
the partner.

This introduces a small API for registering and controlling
cable plug orientation switches, and separate small API for
registering and controlling pin multiplexer/demultiplexer
switches that are needed with Accessory/Alternate Modes.

Heikki Krogerus f2d9b66d84 drivers: base: Unified device connection lookup
Several frameworks - clk, gpio, phy, pmw, etc. - maintain
lookup tables for describing connections and provide custom
API for handling them. This introduces a single generic
lookup table and API for the connections.

The motivation for this commit is centralizing the
connection lookup, but the goal is to ultimately extract the
connection descriptions also from firmware by using the
fwnode_graph_* functions and other mechanisms that are
available.

Richard Leitner 1cbd53c8cd usb: core: introduce per-port over-current counters
For some userspace applications information on the number of
over-current conditions at specific USB hub ports is relevant.

In our case we have a series of USB hardware (using the cp210x driver)
which communicates using a proprietary protocol. These devices sometimes
trigger an over-current situation on some hubs. In case of such an
over-current situation the USB devices offer an interface for reducing
the max used power. As these conditions are quite rare and imply
performance reductions of the device we don't want to reduce the max
power always.

Therefore give user-space applications the possibility to react
adequately by introducing an over_current_counter in the usb port struct
which is exported via sysfs.

Adrian Hunter ad44837882 scsi: ufs: Add support for Auto-Hibernate Idle Timer
UFS host controllers may support an autonomous power management feature
called the Auto-Hibernate Idle Timer. The timer is set to the number of
microseconds of idle time before the UFS host controller will autonomously
put the link into Hibernate state. That will save power at the expense of
increased latency. Any access to the host controller interface registers
will automatically put the link out of Hibernate state. So once configured,
the feature is transparent to the driver.

Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to
choose between power efficiency or lower latency. Set a default value of
150 ms.

Daniel Borkmann says:

====================
pull-request: bpf-next 2018-03-21

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) Add a BPF hook for sendmsg and sendfile by reusing the ULP infrastructure
   and sockmap. Three helpers are added along with this, bpf_msg_apply_bytes(),
   bpf_msg_cork_bytes(), and bpf_msg_pull_data(). The first is used to tell
   for how many bytes the verdict should be applied to, the second to tell
   that x bytes need to be queued first to retrigger the BPF program for a
   verdict, and the third helper is mainly for the sendfile case to pull in
   data for making it private for reading and/or writing, from John.

2) Improve address to symbol resolution of user stack traces in BPF stackmap.
   Currently, the latter stores the address for each entry in the call trace,
   however to map these addresses to user space files, it is necessary to
   maintain the mapping from these virtual addresses to symbols in the binary
   which is not practical for system-wide profiling. Instead, this option for
   the stackmap rather stores the ELF build id and offset for the call trace
   entries, from Song.

3) Add support that allows BPF programs attached to perf events to read the
   address values recorded with the perf events. They are requested through
   PERF_SAMPLE_ADDR via perf_event_open(). Main motivation behind it is to
   support building memory or lock access profiling and tracing tools with
   the help of BPF, from Teng.

4) Several improvements to the tools/bpf/ Makefiles. The 'make bpf' in the
   tools directory does not provide the standard quiet output except for
   bpftool and it also does not respect specifying a build output directory.
   'make bpf_install' command neither respects specified destination nor
   prefix, all from Jiri. In addition, Jakub fixes several other minor issues
   in the Makefiles on top of that, e.g. fixing dependency paths, phony
   targets and more.

5) Various doc updates e.g. add a comment for BPF fs about reserved names
   to make the dentry lookup from there a bit more obvious, and a comment
   to the bpf_devel_QA file in order to explain the diff between native
   and bpf target clang usage with regards to pointer size, from Quentin
   and Daniel.

Detailed description for this pull request:
 1. Add exported extcon function in order to support OF graph binding
 - The extcon consumer driver used the "extcon = <&extcon's phandle"
   property in device-tree in order to bind between extcon provider
   and consumer driver. But, OF graph method is better than 'extcon' property.
   So, extcon subsystem adds the following function to support OF graph binding.
   : extcon_find_edev_by_node(struct device_node *node)
 
 - Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
   and device-tree subsystem. This immutable branch contains the use-case of
   OF graph binding for EXTCON_HDMI connector between MHL device driver
   and extcon provider driver.
 
 2. Fix minor issues of extcon device drivers
 - Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
 - Remove workaround code for id pin direction from extcon-inte-int3496.c
   because GPIO ACPI library does support it with generic way.
 - Set direction and drv flags for V5 boost GPIO because of fixing
   the firmware bug.

David Lechner 21cdf7269f dt-bindings: clock: New bindings for TI Davinci PSC
This adds a new binding for the Power Sleep Controller (PSC) for the
mach-davinci family of processors.

Note: Although TI Keystone has a very similar PSC, we are not using the
existing bindings. Keystone is using a legacy one-node-per-clock binding
(actually two nodes if you count the separate reset binding for the same
IP block). Also, some davinci LPSCs have quirks that aren't handled by
the keystone bindings, so we would be adding one compatible string per
clock with quirks instead of just a new compatible string for each
controller.

This adds a new binding for the PLL IP blocks in the mach-davinci
family of processors. Currently, only da850 has device tree support
but these bindings can also work for other SoCs in this family just
by adding new compatible strings.

Note: Although these PLL controllers are very similar to the TI Keystone
SoCs, we are not re-using those bindings. The Keystone bindings use a
legacy one-node-per-clock binding. Furthermore, the mach-davinici SoCs
have a slightly different PLL register layout and a number of quirks
that can't be handled by the existing bindings, so the keystone bindings
could not be used as-is anyway.

Rafael J. Wysocki 95c513ec84 ACPI: Add Time and Alarm Device (TAD) driver
Introduce a driver for the ACPI Time and Alarm Device (TAD) based on
Section 9.18 of ACPI 6.2.

This driver only supports the system wakeup capabilities of the TAD
which are mandatory.  Support for the RTC capabilities of the TAD
will be added to it in the future.

This driver is entirely sysfs-based.  It provides attributes (under
the TAD platform device) to allow user space to manage the AC and DC
wakeup timers of the TAD: set and read their values, set and check
their expire timer wake policies, check and clear their status and
check the capabilities of the TAD reported by AML.  The DC timer
attributes are only present if the TAD supports a separate DC alarm
timer.

The wakeup events handling and power management of the TAD is
expected to be taken care of by the ACPI PM domain attached to its
platform device.

Kai-Heng Feng 027bd6cafd usb: core: Add "quirks" parameter for usbcore
Trying quirks in usbcore needs to rebuild the driver or the entire
kernel if it's builtin. It can save a lot of time if usbcore has similar
ability like "usbhid.quirks=" and "usb-storage.quirks=".

Rename the original quirk detection function to "static" as we introduce
this new "dynamic" function.

Now users can use "usbcore.quirks=" as short term workaround before the
next kernel release. Also, the quirk parameter can XOR the builtin
quirks for debugging purpose.

This is inspired by usbhid and usb-storage.

drm/sun4i: Add compatible strings for A80 TCONs
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.

In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.

An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.

This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

We're now ready to map our vectors in weird and wonderful locations.
On enabling ARM64_HARDEN_EL2_VECTORS, a vector slot gets allocated
if this hasn't been already done via ARM64_HARDEN_BRANCH_PREDICTOR
and gets mapped outside of the normal RAM region, next to the
idmap.

That way, being able to obtain VBAR_EL2 doesn't reveal the mapping

Khalid Aziz 74a0496748 sparc64: Add support for ADI (Application Data Integrity)
ADI is a new feature supported on SPARC M7 and newer processors to allow
hardware to catch rogue accesses to memory. ADI is supported for data
fetches only and not instruction fetches. An app can enable ADI on its
data pages, set version tags on them and use versioned addresses to
access the data pages. Upper bits of the address contain the version
tag. On M7 processors, upper four bits (bits 63-60) contain the version
tag. If a rogue app attempts to access ADI enabled data pages, its
access is blocked and processor generates an exception. Please see
Documentation/sparc/adi.txt for further details.

This patch extends mprotect to enable ADI (TSTATE.mcde), enable/disable
MCD (Memory Corruption Detection) on selected memory ranges, enable
TTE.mcd in PTEs, return ADI parameters to userspace and save/restore ADI
version tags on page swap out/in or migration. ADI is not enabled by
default for any task. A task must explicitly enable ADI on a memory
range and set version tag for ADI to be effective for the task.

control the policy of fsync. "fsync_mode=posix" is set by default,
and means that f2fs uses a light fsync, which follows POSIX semantics.
And "fsync_mode=strict" means that it's a heavy fsync, which behaves
in line with xfs, ext4 and btrfs, where generic/342 will pass, but
the performance will regress.

Tony Lindgren 5d1ebbda03 phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4
Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.

The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.

The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.

The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.

Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.

Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.

For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:

idle lcd off	phy-mapphone-mdm6600	ohci-platform
153mW		284mW			344mW

So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

Arnd Bergmann bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

Alexander Usyskin af336cabe0 mei: limit the number of queued writes
Limit the number of queued writes per client.
Writes above this threshold are blocked till place
in the transmit queue is available.
The limit is configurable via sysfs and defaults to 50.
The implementation should provide blocking I/O behavior.
Prior to this change one would end up in the hands of OOM.

This change introduces a proposed layout for describing FSI busses in
the device tree. While the bus is probe-able, we'd still like a method
of describing subordinate (eg i2c) busses that are behind FSI devices.

The FSI core will be responsible for matching probed slaves & engines to
their device tree nodes, so the FSI device drivers' probe() functions
will be passed a struct device with the appropriate of_node populated
where a matching DT node is found.

Jeremy Kerr b8bd146d38 fsi: master-gpio: Add external mode
This change introduces an 'external mode' for GPIO-based FSI masters,
allowing the clock and data lines to be driven by an external source.
For example, external mode is selected by a user when an external debug
device is attached to the FSI pins.

To do this, we need to set specific states for the trans, mux and enable
GPIOs, and prevent access to clk & data from the FSI core code (by
returning EBUSY).

External mode is controlled by a sysfs attribute, so add the relevant
information to Documentation/ABI/

Willem de Bruijn ced68234b6 sock: remove zerocopy sockopt restriction on closed tcp state
Socket option SO_ZEROCOPY determines whether the kernel ignores or
processes flag MSG_ZEROCOPY on subsequent send calls. This to avoid
changing behavior for legacy processes.

Limiting the state change to closed sockets is annoying with passive
sockets and not necessary for correctness. Once created, zerocopy skbs
are processed based on their private state, not this socket flag.

Remove the constraint.

Marc Zyngier f736d65df0 irqchip/gic-v3: Allow LPIs to be disabled from the command line
For most GICv3 implementations, enabling LPIs is a one way switch.
Once they're on, there is no turning back, which completely kills
kexec (pending tables will always be live, and we can't tell the
secondary kernel where they are).

This is really annoying if you plan to use Linux as a bootloader,
as it pretty much guarantees that the secondary kernel won't be
able to use MSIs, and may even see some memory corruption. Bad.

A workaround for this unfortunate situation is to allow the kernel
not to enable LPIs, even if the feature is present in the HW. This
would allow Linux-as-a-bootloader to leave LPIs alone, and let the
secondary kernel to do whatever it wants with them.

Let's introduce a boolean "irqchip.gicv3_nolpi" command line option
that serves that purpose.

Xiaofei Tan 4c40db995e scsi: hisi_sas: dt-bindings: add an property of signal attenuation
For some new boards with hip07 chipset we are required to set PHY config
registers differently. The hw property which determines how to set these
registers is in the PHY signal attenuation readings.

This patch add an devicetree property, "hisilicon,signal-attenuation", which
is used to describe the signal attenuation of an board.

Chao Yu b6a06cbbb5 f2fs: support hot file extension
This patch supports to recognize hot file extension in f2fs, so that we
can allocate proper hot segment location for its data, which can lead to
better hot/cold seperation in filesystem.

In addition, we changes a bit on query/add/del operation method for
extension_list sysfs entry as below:

- Query: cat /sys/fs/f2fs/<disk>/extension_list
- Add: echo 'extension' > /sys/fs/f2fs/<disk>/extension_list
- Del: echo '!extension' > /sys/fs/f2fs/<disk>/extension_list
- Add: echo '[h/c]extension' > /sys/fs/f2fs/<disk>/extension_list
- Del: echo '[h/c]!extension' > /sys/fs/f2fs/<disk>/extension_list
- [h] means add/del hot file extension

Gregory CLEMENT 3cd2c313f1 dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.

With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

Pull RCU updates from Paul E. McKenney:

 - Miscellaneous fixes, perhaps most notably removing obsolete
   code whose only purpose in life was to gather information for
   the now-removed RCU debugfs facility.  Other notable changes
   include removing NO_HZ_FULL_ALL in favor of the nohz_full kernel
   boot parameter, minor optimizations for expedited grace periods,
   some added tracing, creating an RCU-specific workqueue using Tejun's
   new WQ_MEM_RECLAIM flag, and several cleanups to code and comments.

 - SRCU cleanups and optimizations.

 - Torture-test updates, perhaps most notably the adding of ARMv8
   support, but also including numerous cleanups and usability fixes.

information about what went wrong, if information is available.  This
extended error information will be available until the next hist
trigger command for that event.

  # echo xxx > /sys/kernel/debug/tracing/events/sched/sched_wakeup/trigger
  echo: write error: Invalid argument

  # cat /sys/kernel/debug/tracing/events/sched/sched_wakeup/hist

  ERROR: Couldn't yyy: zzz

Add a new option flag indicating whether or not the ring buffer is in
'absolute timestamp' mode.

Currently this is only set/unset by hist triggers that make use of a
common_timestamp.  As such, there's no reason to make this writeable
for users - its purpose is only to allow users to determine
unequivocally whether or not the ring buffer is in that mode (although
absolute timestamps can coexist with the normal delta timestamps, when
the ring buffer is in absolute mode, timestamps written while absolute
mode is in effect take up more space in the buffer, and are not as
efficient).

Chen-Yu Tsai 8591743f12 ARM: sunxi: mc-smp: Use DT enable-method for sun9i A80 SMP
Instead of having an early init function check the machine compatible
and installing multi-cluster SMP support for the A80 if it matches,
use a new cpu enable-method string. This makes the platform support
future proof in case anyone manages to add PSCI support.

The original init code for the SMP support is changed into the
.prepare_cpus callback in the smp_operations structure. Instead of
panicing when resources are missing like on some platforms, our code
merely guards against engaging SMP or CPU hotplug and returns an error.

The Fujitsu FRV kernel port has been around for a long time, but has not

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

Trying quirks in usbcore needs to rebuild the driver or the entire
kernel if it's builtin. It can save a lot of time if usbcore has similar
ability like "usbhid.quirks=" and "usb-storage.quirks=".

Rename the original quirk detection function to "static" as we introduce
this new "dynamic" function.

Now users can use "usbcore.quirks=" as short term workaround before the
next kernel release. Also, the quirk parameter can XOR the builtin
quirks for debugging purpose.

This is inspired by usbhid and usb-storage.

ASoC: da7219: Add common clock usage for providing DAI clks
There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.

The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

Eric Dumazet 79134e6ce2 net: do not create fallback tunnels for non-default namespaces
fallback tunnels (like tunl0, gre0, gretap0, erspan0, sit0,
ip6tnl0, ip6gre0) are automatically created when the corresponding
module is loaded.

These tunnels are also automatically created when a new network
namespace is created, at a great cost.

In many cases, netns are used for isolation purposes, and these
extra network devices are a waste of resources. We are using
thousands of netns per host, and hit the netns creation/delete
bottleneck a lot. (Many thanks to Kirill for recent work on this)

Add a new sysctl so that we can opt-out from this automatic creation.

Note that these tunnels are still created for the initial namespace,
to be the least intrusive for typical setups.

On Armada 7K/8K we need to explicitly enable the register clock. This

Mika Westerberg 6fc14e1a44 thunderbolt: Introduce USB only (SL4) security level
This new security level works so that it creates one PCIe tunnel to the
connected Thunderbolt dock, removing PCIe links downstream of the dock.
This leaves only the internal USB controller visible.

Display Port tunnels are created normally.

While there make sure security sysfs attribute returns "unknown" for any
future security level.

Mika Westerberg 9aaa3b8b4c thunderbolt: Add support for preboot ACL
Preboot ACL is a mechanism that allows connecting Thunderbolt devices
boot time in more secure way than the legacy Thunderbolt boot support.
As with the legacy boot option, this also needs to be enabled from the
BIOS before booting is allowed. Difference to the legacy mode is that
the userspace software explicitly adds device UUIDs by sending a special
message to the ICM firmware. Only the devices listed in the boot ACL are
connected automatically during the boot. This works in both "user" and
"secure" security levels.

We implement this in Linux by exposing a new sysfs attribute (boot_acl)
below each Thunderbolt domain. The userspace software can then update
the full list as needed.

Yehezkel Bernat 14862ee308 thunderbolt: Add 'boot' attribute for devices
In various cases, Thunderbolt device can be connected by ICM on boot
without waiting for approval from user. Most cases are related to
OEM-specific BIOS configurations. This information is interesting for
user-space as if the device isn't in SW ACL, it may create a friction in
the user experience where the device is automatically authorized if it's
connected on boot but requires an explicit user action if connected
after OS is up. User-space can use this information to suggest adding
the device to SW ACL for auto-authorization on later connections.
