5bbd21df5a devlink: add 'reset_dev_on_drv_probe' param
Add the 'reset_dev_on_drv_probe' devlink parameter, controlling the
device reset policy on driver probe.

This parameter is useful in conjunction with the existing
'fw_load_policy' parameter.

extract any namespace suffix from the symbol name. In addition, emit a

explicitly importing the namespace that it is defined in. This patch
consistently adds the namespace suffix to symbol names exported into
Module.symvers.

Example warning emitted by modpost in case of the above violation:

 USB_STORAGE, but does not import it.

92f35b751c KVM: arm/arm64: vgic: Allow more than 256 vcpus for KVM_IRQ_LINE
While parts of the VGIC support a large number of vcpus (we
bravely allow up to 512), other parts are more limited.

One of these limits is visible in the KVM_IRQ_LINE ioctl, which
only allows 256 vcpus to be signalled when using the CPU or PPI
types. Unfortunately, we've cornered ourselves badly by allocating
all the bits in the irq field.

Since the irq_type subfield (8 bit wide) is currently only taking
the values 0, 1 and 2 (and we have been careful not to allow anything
else), let's reduce this field to only 4 bits, and allocate the
remaining 4 bits to a vcpu2_index, which acts as a multiplier:

  vcpu_id = 256 * vcpu2_index + vcpu_index

With that, and a new capability (KVM_CAP_ARM_IRQ_LINE_LAYOUT_2)
allowing this to be discovered, it becomes possible to inject
PPIs to up to 4096 vcpus. But please just don't.

Whilst we're there, add a clarification about the use of KVM_IRQ_LINE
on arm, which is not completely conditionned by KVM_CAP_IRQCHIP.

Daniel Borkmann says:

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

The main changes are:

1) Add the ability to use unaligned chunks in the AF_XDP umem. By
   relaxing where the chunks can be placed, it allows to use an
   arbitrary buffer size and place whenever there is a free
   address in the umem. Helps more seamless DPDK AF_XDP driver
   integration. Support for i40e, ixgbe and mlx5e, from Kevin and
   Maxim.

2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
   application can wake up the kernel for rx/tx processing which
   avoids busy-spinning of the latter, useful when app and driver
   is located on the same core. Support for i40e, ixgbe and mlx5e,
   from Magnus and Maxim.

3) bpftool fixes for printf()-like functions so compiler can actually
   enforce checks, bpftool build system improvements for custom output
   directories, and addition of 'bpftool map freeze' command, from Quentin.

4) Support attaching/detaching XDP programs from 'bpftool net' command,
   from Daniel.

5) Automatic xskmap cleanup when AF_XDP socket is released, and several
   barrier/{read,write}_once fixes in AF_XDP code, from Björn.

6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
   inclusion as well as libbpf versioning improvements, from Andrii.

7) Several new BPF kselftests for verifier precision tracking, from Alexei.

8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.

9) And more BPF kselftest improvements all over the place, from Stanislav.

10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.

11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan.

12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni.

13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin.

14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar.

15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari,
    Peter, Wei, Yue.

Rename it to more sensible, shorter KBUILD_EXTRA_WARN.

For the backward compatibility, KBUILD_ENABLE_EXTRA_GCC_CHECKS is still
supported (but not advertised in the documentation).

I also fixed up 'make help', and updated the documentation.

0760bb9ac9 PM: runtime: Documentation: add runtime_status ABI document
/sys/devices/.../power/runtime_status is introduced by commit c92445fadb
("PM / Runtime: Add sysfs debug files").  Then commit 0fcb4eef82 ("PM /
Runtime: Make runtime_status attribute not debug-only (v. 2)") made the
runtime_status attribute available without CONFIG_PM_ADVANCED_DEBUG.

This adds missing runtime_status ABI document.

As Christoph said [1],
"vm_map_ram is supposed to generally behave better.  So if
it doesn't please report that that to the arch maintainer
and linux-mm so that they can look into the issue.  Having
user make choices of deep down kernel internals is just
a horrible interface.

Please talk to maintainers of other bits of the kernel
if you see issues and / or need enhancements. "

Let's redo the previous conclusion and kill the vmap
approach.

ASoC: meson: add reset binding
The g12a audio subsystem, which is a derivative of the axg subsystem,
provides a dedicated reset line for each of the audio components.

The axg did not provide that and it is unclear if/when these reset are
required. The reset already helped solve a channel mapping issue on the
tdm formatter devices. Let's add the reset binding for the other
components, so we can describe this in DT. We'll use it later on
in the driver when/if needed.

====================
pull-request: can-next 2019-09-04 j1939

this is a pull request for net-next/master consisting of 21 patches.

the first 12 patches are by me and target the CAN core infrastructure.
They clean up the names of variables , structs and struct members,
convert can_rx_register() to use max() instead of open coding it and
remove unneeded code from the can_pernet_exit() callback.

The next three patches are also by me and they introduce and make use of
the CAN midlayer private structure. It is used to hold protocol specific
per device data structures.

The next patch is by Oleksij Rempel, switches the
&net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that
it can be used from NAPI (soft IRQ) context.

The next 4 patches are by Kurt Van Dijck, he first updates his email
address via mailmap and then extends sockaddr_can to include j1939
members.

The final patch is the collective effort of many entities (The j1939
authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test
robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij
Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the
CAN networking stack.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.

P.S.: This pull request doesn't invalidate my last pull request:
      "pull-request: can-next 2019-09-03".

pull-request: can-next 2019-09-03

this is a pull request for net-next/master consisting of 15 patches.

The first patch is by Christer Beskow, targets the kvaser_pciefd driver
and fixes the PWM generator's frequency.

The next three patches are by Dan Murphy, the tcan4x5x is updated to use
a proper interrupts/interrupt-parent DT binding to specify the devices
IRQ line. Further the unneeded wake ups of the device is removed from
the driver.

A patch by me for the mcp25xx driver removes the deprecated board file
setup example. Three patches by Andy Shevchenko simplify clock handling,
update the driver from OF to device property API and simplify the
mcp251x_can_suspend() function.

The remaining 7 patches are by me and clean up checkpatch warnings in
the generic CAN device infrastructure.

2a4bfd023f hwrng: timeriomem - relax check on memory resource size
The timeriomem_rng driver only accesses the first 4 bytes of the given
memory area and currently, it also forces that memory resource to be
exactly 4 bytes in size.

This, however, is problematic when used with device-trees that are
generated from things like FPGA toolchains, where the minimum size
of an exposed memory block may be something like 4k.

Hence, let's only check for what's needed for the driver to operate
properly; namely that we have enough memory available to read the
random data from.

2275d7b575 powerpc/64s/radix: introduce options to disable use of the tlbie instruction
Introduce two options to control the use of the tlbie instruction. A
boot time option which completely disables the kernel using the
instruction, this is currently incompatible with HASH MMU, KVM, and
coherent accelerators.

And a debugfs option can be switched at runtime and avoids using tlbie
for invalidating CPU TLBs for normal process and kernel address
mappings. Coherent accelerators are still managed with tlbie, as will
KVM partition scope translations.

Cross-CPU TLB flushing is implemented with IPIs and tlbiel. This is a
basic implementation which does not attempt to make any optimisation
beyond the tlbie implementation.

This is useful for performance testing among other things. For example
in certain situations on large systems, using IPIs may be faster than
tlbie as they can be directed rather than broadcast. Later we may also
take advantage of the IPIs to do more interesting things such as trim
the mm cpumask more aggressively.

SAE J1939 is the vehicle bus recommended practice used for communication
and diagnostics among vehicle components. Originating in the car and
heavy-duty truck industry in the United States, it is now widely used in
other parts of the world.

J1939, ISO 11783 and NMEA 2000 all share the same high level protocol.
SAE J1939 can be considered the replacement for the older SAE J1708 and
SAE J1587 specifications.

09864c1cdf tty: serial: Add linflexuart driver for S32V234
Introduce support for LINFlex driver, based on:
- the version of Freescale LPUART driver after commit b3e3bf2ef2 ("Merge
  4.0-rc7 into tty-next");
- commit abf1e0a980 ("tty: serial: fsl_lpuart: lock port on console
  write").
In this basic version, the driver can be tested using initramfs and relies
on the clocks and pin muxing set up by U-Boot.

Remarks concerning the earlycon support:

- LinFlexD does not allow character transmissions in the INIT mode (see
  section 47.4.2.1 in the reference manual[1]). Therefore, a mutual
  exclusion between the first linflex_setup_watermark/linflex_set_termios
  executions and linflex_earlycon_putchar was employed and the characters
  normally sent to earlycon during initialization are kept in a buffer and
  sent afterwards.

- Empirically, character transmission is also forbidden within the last 1-2
  ms before entering the INIT mode, so we use an explicit timeout
  (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to
  linflex_setup_watermark.

- U-Boot currently uses the UART FIFO mode, while this driver makes the
  transition to the buffer mode. Therefore, the earlycon putchar function
  matches the U-Boot behavior before initializations and the Linux behavior
  after.

94810bd365 mlx5-updates-2019-09-01 (Software steering support)
Abstract:
 --------
 Mellanox ConnetX devices supports packet matching, packet modification and
 redirection. These functionalities are also referred to as flow-steering.
 To configure a steering rule, the rule is written to the device owned
 memory, this memory is accessed and cached by the device when processing
 a packet.
 Steering rules are constructed from multiple steering entries (STE).
 
 Rules are configured using the Firmware command interface. The Firmware
 processes the given driver command and translates them to STEs, then
 writes them to the device memory in the current steering tables.
 This process is slow due to the architecture of the command interface and
 the processing complexity of each rule.
 
 The highlight of this patchset is to cut the middle man (The firmware) and
 do steering rules programming into device directly from the driver, with
 no firmware intervention whatsoever.
 
 Motivation:
 -----------
 Software (driver managed) steering allows for high rule insertion rates
 compared to the FW steering described above, this is achieved by using
 internal RDMA writes to the device owned memory instead of the slow
 command interface to program steering rules.
 
 Software (driver managed) steering, doesn't depend on new FW
 for new steering functionality, new implementations can be done in the
 driver skipping the FW layer.
 
 Performance:
 ------------
 The insertion rate on a single core using the new approach allows
 programming ~300K rules per sec. (Done via direct raw test to the new mlx5
 sw steering layer, without any kernel layer involved).
 
 Test: TC L2 rules
 33K/s with Software steering (this patchset).
 5K/s  with FW and current driver.
 This will improve OVS based solution performance.
 
 Architecture and implementation details:
 ----------------------------------------
 Software steering will be dynamically selected via devlink device
 parameter. Example:
 $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
           pci/0000:06:00.0:
           name flow_steering_mode type driver-specific
           values:
              cmode runtime value smfs
 
 mlx5 software steering module a.k.a (DR - Direct Rule) is implemented
 and contained in mlx5/core/steering directory and controlled by
 MLX5_SW_STEERING kconfig flag.
 
 mlx5 core steering layer (fs_core) already provides a shim layer for
 implementing different steering mechanisms, software steering will
 leverage that as seen at the end of this series.
 
 When Software Steering for a specific steering domain
 (NIC/RDMA/Vport/ESwitch, etc ..) is supported, it will cause rules
 targeting this domain to be created using  SW steering instead of FW.
 
 The implementation includes:
 Domain - The steering domain is the object that all other object resides
     in. It holds the memory allocator, send engine, locks and other shared
     data needed by lower objects such as table, matcher, rule, action.
     Each domain can contain multiple tables. Domain is equivalent to
     namespaces e.g (NIC/RDMA/Vport/ESwitch, etc ..) as implemented
     currently in mlx5_core fs_core (flow steering core).
 
 Table - Table objects are used for holding multiple matchers, each table
     has a level used to prevent processing loops. Packets are being
     directed to this table once it is set as the root table, this is done
     by fs_core using a FW command. A packet is being processed inside the
     table matcher by matcher until a successful hit, otherwise the packet
     will perform the default action.
 
 Matcher - Matchers objects are used to specify the fields mask for
     matching when processing a packet. A matcher belongs to a table, each
     matcher can hold multiple rules, each rule with different matching
     values corresponding to the matcher mask. Each matcher has a priority
     used for rule processing order inside the table.
 
 Action - Action objects are created to specify different steering actions
     such as count, reformat (encapsulate, decapsulate, ...), modify
     header, forward to table and many other actions. When creating a rule
     a sequence of actions can be provided to be executed on a successful
     match.
 
 Rule - Rule objects are used to specify a specific match on packets as
     well as the actions that should be executed. A rule belongs to a
     matcher.
 
 STE - This layer is used to hold the specific STE format for the device
     and to convert the requested rule to STEs. Each rule is constructed of
     an STE chain, Multiple rules construct a steering graph. Each node in
     the graph is a hash table containing multiple STEs. The index of each
     STE in the hash table is being calculated using a CRC32 hash function.
 
 Memory pool - Used for managing and caching device owned memory for rule
     insertion. The memory is being allocated using DM (device memory) API.
 
 Communication with device - layer for standard RDMA operation using  RC QP
     to configure the device steering.
 
 Command utility - This module holds all of the FW commands that are
     required for SW steering to function.
 
 Patch planning and files:
 -------------------------
 1) First patch, adds the support to Add flow steering actions to fs_cmd
 shim layer.
 
 2) Next 12 patch will add a file per each Software steering
 functionality/module as described above. (See patches with title: DR, *)
 
 3) Add CONFIG_MLX5_SW_STEERING for software steering support and enable
 build with the new files
 
 4) Next two patches will add the support for software steering in mlx5
 steering shim layer
 net/mlx5: Add API to set the namespace steering mode
 net/mlx5: Add direct rule fs_cmd implementation
 
 5) Last two patches will add the new devlink parameter to select mlx5
 steering mode, will be valid only for switchdev mode for now.
 Two modes are supported:
     1. DMFS - Device managed flow steering
     2. SMFS - Software/Driver managed flow steering.
 
     In the DMFS mode, the HW steering entities are created through the
     FW. In the SMFS mode this entities are created though the driver
     directly.
 
     The driver will use the devlink steering mode only if the steering
     domain supports it, for now SMFS will manages only the switchdev
     eswitch steering domain.
 
     User command examples:
     - Set SMFS flow steering mode::
 
         $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime
 
     - Read device flow steering mode::
 
         $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
           pci/0000:06:00.0:
           name flow_steering_mode type driver-specific
           values:
              cmode runtime value smfs

74eb9c06b1 Second set of new device support, cleanups and features for IIO in the 5.4 cycle
Revised pull request to fix up a missing Signed-off-by and roll in
 a fix in the lsm9ds1 support after I broke it when applying.
 Revised again because the fix changed a hash meaning a fix
 that previously followed it now had the wrong fixes tag.
 
 A few fixes in here that could have gone a faster path but aren't quite
 worth the rush for 5.3.
 
 New device support
 * ad7606
   - Support the ad7606b which adds a software controlled mode alongside
     the pin controlled only approach of the ad7606. Including dt-bindings.
 * lsm6dsx
   - Add support for the gyro and accelerometer part of the lsm9ds1 which is
     a compound device also including a magnetometer (st_sensors driver).
     Includes bindings and precursor rework of the driver.
 
 Features
 * ad7192
   - Add support for low pass filter control.
   - DT binding docs.
 
 Cleanups and minor fixes
 * MAINTAINERS
   - Fix a typo in a path.
   - Add entry for ad7606
 * ad5380
   - Fix a failure to dereference a pointer before atempting to assign the
     value.
 * ad7192
   - Drop platform data as not used in mainline and we now have full DT bindings.
 * ad7606
   - YAML conversion for dt-bindings.
 * adis16240
   - Rework write_raw to make it more readable using GENMASK.
 * adis16460
   - Fix and issue with an unsigned variable holding potential negatives.
 * cros_ec
   - Fix missing default of calibration vector so that we get 'something'
     before calibration is complete on a given axis.
 * hid-sensors
   - Use int_pow instead of opencoding.
 * isl29501
   - rename dt-binding docs to include renesas inline with other renesas parts
     and general current convention.
 * kxcjk1013
   - Improve comments on the 'unusual' ACPI ids used to identify which sensor
     is which in certain laptops.
 * lsm6dsx
   - Add one bit to the fifo status masks for a number of parts.
   - Drop a reserved entry from the sensitivity values to tidy up interface.
   - Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier
     to relate to the datasheet and consistent with other parts supported.
 * max1027
   - Use device managed APIs to avoid manual error handling and cleanup.
 * rfd77402
   - Typo in Kconfig help.
 * sc27xx
   - Switch to polling mode from interrupts as interrupt handling typically
     to slow for very short sleeps.
 * st-sensors
   - Fix some missing selects for regmap.
 * tools
   - Add a .gitignore containing the binary outputs.

e890acd5ff net/mlx5: Add devlink flow_steering_mode parameter
Add new parameter (flow_steering_mode) to control the flow steering
mode of the driver.
Two modes are supported:
1. DMFS - Device managed flow steering
2. SMFS - Software/Driver managed flow steering.

In the DMFS mode, the HW steering entities are created through the
FW. In the SMFS mode this entities are created though the driver
directly.

The driver will use the devlink steering mode only if the steering
domain supports it, for now SMFS will manages only the switchdev eswitch
steering domain.

User command examples:
- Set SMFS flow steering mode::

    $ devlink dev param set pci/0000:06:00.0 name flow_steering_mode value "smfs" cmode runtime

- Read device flow steering mode::

    $ devlink dev param show pci/0000:06:00.0 name flow_steering_mode
      pci/0000:06:00.0:
      name flow_steering_mode type driver-specific
      values:
         cmode runtime value smfs

4a79ce748f interconnect patches for 5.4
Here are the interconnect driver updates for the 5.4-rc1 merge window.
 
 - New feature is the path tagging support that helps with grouping and
 aggregating the bandwidth requests into separate buckets based on a tag.
 - The first user of the path tagging is the Qualcomm sdm845 driver that
 now implements support for wake/sleep sets. This allows consumer drivers
 to express their bandwidth needs for the different CPU power states.
 - New interconnect driver for the qcs404 platforms and a driver that
 communicates bandwidth requests with remote processor over shared memory.
 - Cleanups and fixes.

2480c09313 sched/uclamp: Extend CPU's cgroup controller
The cgroup CPU bandwidth controller allows to assign a specified
(maximum) bandwidth to the tasks of a group. However this bandwidth is
defined and enforced only on a temporal base, without considering the
actual frequency a CPU is running on. Thus, the amount of computation
completed by a task within an allocated bandwidth can be very different
depending on the actual frequency the CPU is running that task.
The amount of computation can be affected also by the specific CPU a
task is running on, especially when running on asymmetric capacity
systems like Arm's big.LITTLE.

With the availability of schedutil, the scheduler is now able
to drive frequency selections based on actual task utilization.
Moreover, the utilization clamping support provides a mechanism to
bias the frequency selection operated by schedutil depending on
constraints assigned to the tasks currently RUNNABLE on a CPU.

Giving the mechanisms described above, it is now possible to extend the
cpu controller to specify the minimum (or maximum) utilization which
should be considered for tasks RUNNABLE on a cpu.
This makes it possible to better defined the actual computational
power assigned to task groups, thus improving the cgroup CPU bandwidth
controller which is currently based just on time constraints.

Extend the CPU controller with a couple of new attributes uclamp.{min,max}
which allow to enforce utilization boosting and capping for all the
tasks in a group.

Specifically:

- uclamp.min: defines the minimum utilization which should be considered
	      i.e. the RUNNABLE tasks of this group will run at least at a
	      minimum frequency which corresponds to the uclamp.min
	      utilization

- uclamp.max: defines the maximum utilization which should be considered
	      i.e. the RUNNABLE tasks of this group will run up to a
	      maximum frequency which corresponds to the uclamp.max
	      utilization

These attributes:

a) are available only for non-root nodes, both on default and legacy
   hierarchies, while system wide clamps are defined by a generic
   interface which does not depends on cgroups. This system wide
   interface enforces constraints on tasks in the root node.

b) enforce effective constraints at each level of the hierarchy which
   are a restriction of the group requests considering its parent's
   effective constraints. Root group effective constraints are defined
   by the system wide interface.
   This mechanism allows each (non-root) level of the hierarchy to:
   - request whatever clamp values it would like to get
   - effectively get only up to the maximum amount allowed by its parent

c) have higher priority than task-specific clamps, defined via
   sched_setattr(), thus allowing to control and restrict task requests.

Add two new attributes to the cpu controller to collect "requested"
clamp values. Allow that at each non-root level of the hierarchy.
Keep it simple by not caring now about "effective" values computation
and propagation along the hierarchy.

Update sysctl_sched_uclamp_handler() to use the newly introduced
uclamp_mutex so that we serialize system default updates with cgroup
relate updates.

This driver can use GPIO descriptors rather than GPIO numbers

d55c028f8b backlight: Expose brightness curve type through sysfs
Backlight brightness curves can have different shapes. The two main
types are linear and non-linear curves. The human eye doesn't
perceive linearly increasing/decreasing brightness as linear (see
also 88ba95bedb "backlight: pwm_bl: Compute brightness of LED
linearly to human eye"), hence many backlights use non-linear (often
logarithmic) brightness curves. The type of curve currently is opaque
to userspace, so userspace often uses more or less reliable heuristics
(like the number of brightness levels) to decide whether to treat a
backlight device as linear or non-linear.

Export the type of the brightness curve via the new sysfs attribute
'scale'. The value of the attribute can be 'linear', 'non-linear' or
'unknown'. For devices that don't provide information about the scale
of their brightness curve the value of the 'scale' attribute is 'unknown'.

6218bf9f4d tracing/probe: Add immediate parameter support
Add immediate value parameter (\1234) support to
probe events. This allows you to specify an immediate
(or dummy) parameter instead of fetching from memory
or register.

This feature looks odd, but imagine when you put a probe
on a code to trace some data. If the code is compiled into
2 instructions and 1 instruction has a value but other has
nothing since it is optimized out.
In that case, you can not fold those into one event, even
if ftrace supported multiple probes on one event.
With this feature, you can set a dummy value like
foo=\deadbeef instead of something like foo=%di.

d57f172c99 doc/af_xdp: include unaligned chunk case
The addition of unaligned chunks mode, the documentation needs to be
updated to indicate that the incoming addr to the fill ring will only be
masked if the user application is run in the aligned chunk mode. This patch
also adds a line to explicitly indicate that the incoming addr will not be
masked if running the user application in the unaligned chunk mode.

ASoC: dt-bindings: Convert Allwinner A64 analog codec to a schema
The Allwinner A64 SoC has an embedded audio codec that uses a separate

Now that we have the DT validation in place, let's convert the device tree

29746d0125 dt-bindings: mediatek: Add binding for mt8183 IOMMU and SMI
This patch adds decriptions for mt8183 IOMMU and SMI.

mt8183 has only one M4U like mt8173 and is also MTK IOMMU gen2 which
uses ARM Short-Descriptor translation table format.

The mt8183 M4U-SMI HW diagram is as below:

                          EMI
                           |

All the connections are HW fixed, SW can NOT adjust it.

Compared with mt8173, we add a GALS(Global Async Local Sync) module
between SMI-common and M4U, and additional GALS between larb2/3/5/6
and SMI-common. GALS can help synchronize for the modules in different
clock frequency, it can be seen as a "asynchronous fifo".

GALS can only help transfer the command/data while it doesn't have
the configuring register, thus it has the special "smi" clock and it
doesn't have the "apb" clock. From the diagram above, we add "gals0"
and "gals1" clocks for smi-common and add a "gals" clock for smi-larb.

>From the diagram above, IPU0/IPU1(Image Processor Unit) and CCU(Camera
Control Unit) is connected with smi-common directly, we can take them
as "larb2", "larb3" and "larb7", and their register spaces are
different with the normal larb.

Protected Execution Facility (PEF) is an architectural change for
POWER 9 that enables Secure Virtual Machines (SVMs). When enabled,
PEF adds a new higher privileged mode, called Ultravisor mode, to POWER
architecture. Along with the new mode there is new firmware called the
Protected Execution Ultravisor (or Ultravisor for short).

POWER 9 DD2.3 chips (PVR=0x004e1203) or greater will be PEF-capable.

Attached documentation provides an overview of PEF and defines the API
for various interfaces that must be implemented in the Ultravisor
firmware as well as in the KVM Hypervisor.

interrupts from more than one interrupt controller. This isn't true. We
should encourage devicetree writers to use this property in situations
where it isn't the inherited interrupt-parent so that we have less
properties in a DT node by virtue of not having to specify an

7caa47151a blkcg: implement blk-iocost
This patchset implements IO cost model based work-conserving
proportional controller.

While io.latency provides the capability to comprehensively prioritize
and protect IOs depending on the cgroups, its protection is binary -
the lowest latency target cgroup which is suffering is protected at
the cost of all others.  In many use cases including stacking multiple
workload containers in a single system, it's necessary to distribute
IO capacity with better granularity.

One challenge of controlling IO resources is the lack of trivially
observable cost metric.  The most common metrics - bandwidth and iops
- can be off by orders of magnitude depending on the device type and
IO pattern.  However, the cost isn't a complete mystery.  Given
several key attributes, we can make fairly reliable predictions on how
expensive a given stream of IOs would be, at least compared to other
IO patterns.

The function which determines the cost of a given IO is the IO cost
model for the device.  This controller distributes IO capacity based
on the costs estimated by such model.  The more accurate the cost
model the better but the controller adapts based on IO completion
latency and as long as the relative costs across differents IO
patterns are consistent and sensible, it'll adapt to the actual
performance of the device.

Currently, the only implemented cost model is a simple linear one with
a few sets of default parameters for different classes of device.
This covers most common devices reasonably well.  All the
infrastructure to tune and add different cost models is already in
place and a later patch will also allow using bpf progs for cost
models.

Please see the top comment in blk-iocost.c and documentation for
more details.

Convert the Arm Bifrost GPU binding to DT schema format.

The 'clocks' property is now required. This simplifies the schema as
effectively all the users require 'clocks' already and the upstream
driver requires at least one clock.

ddaedbbece Documentation/process: Embargoed hardware security issues
To address the requirements of embargoed hardware issues, like Meltdown,
Spectre, L1TF etc. it is necessary to define and document a process for
handling embargoed hardware security issues.

Following the discussion at the maintainer summit 2018 in Edinburgh
(https://lwn.net/Articles/769417/) the volunteered people have worked
out a process and a Memorandum of Understanding.  The latter addresses
the fact that the Linux kernel community cannot sign NDAs for various
reasons.

The initial contact point for hardware security issues is different from
the regular kernel security contact to provide a known and neutral
interface for hardware vendors and researchers. The initial primary
contact team is proposed to be staffed by Linux Foundation Fellows, who
are not associated to a vendor or a distribution and are well connected
in the industry as a whole.

The process is designed with the experience of the past incidents in
mind and tries to address the remaining gaps, so future (hopefully rare)
incidents can be handled more efficiently.  It won't remove the fact,
that most of this has to be done behind closed doors, but it is set up
to avoid big bureaucratic hurdles for individual developers.

The process is solely for handling hardware security issues and cannot
be used for regular kernel (software only) security bugs.

This memo can help with hardware companies who, and I quote, "[my
manager] doesn't want to bet his job on the list keeping things secret."
This despite numerous leaks directly from that company over the years,
and none ever so far from the kernel security team.  Cognitive
dissidence seems to be a requirement to be a good manager.

To accelerate the adoption of this  process, we introduce the concept of
ambassadors in participating companies. The ambassadors are there to
guide people to comply with the process, but are not automatically
involved in the disclosure of a particular incident.

removed the cc-ldoption from Documentation/kbuild/makefiles.txt, but
commit cd238effef ("docs: kbuild: convert docs to ReST and rename

I see the following warnings when I open this document with a ReST

/home/masahiro/ref/linux/Documentation/kbuild/makefiles.rst:1154: (WARNING/2) Inline emphasis start-string without end-string.

These hunks were added by commit e846f0dc57 ("kbuild: add support
for ensuring headers are self-contained") and commit 1e21cbfada
("kbuild: support header-test-pattern-y"), respectively. They were
written not for ReST but for the plain text, and merged via the
kbuild tree.

In the same development cycle, this document was converted to ReST
by commit cd238effef ("docs: kbuild: convert docs to ReST and rename

Merging them together into Linus' tree resulted in the current situation.

To fix the syntax, surround the asterisks with back-quotes, and
use :: for the code sample.

  properties is simply not used.)

- There's no need to refer to the sensor device in the DT example, thus
  remove the label.

- Rename the "camera" device node as "camera-sensor".

- Rename the endpoint label as "smiapp_ep" (was: "smiapp_1_1"). There is
  in practice only one anyway.

- Remove the remote-endpoint documentation (it is covered by
  graph.txt to which video-interfaces.txt refers to).

- Add a note on the port and endpoint nodes.

1be8c9fd2a dt-bindings: timer: renesas, cmt: Update R-Car Gen3 CMT1 usage
The R-Car Gen3 SoCs so far come with a total for 4 on-chip CMT devices:
 - CMT0
 - CMT1
 - CMT2
 - CMT3

CMT0 includes two rather basic 32-bit timer channels. The rest of the on-chip
CMT devices support 48-bit counters and have 8 channels each.

Based on the data sheet information "CMT2/3 are exactly same as CMT1"
it seems that CMT2 and CMT3 now use the CMT1 compat string in the DTSI.

Clarify this in the DT binding documentation by describing R-Car Gen3 and
RZ/G2 CMT1 as "48-bit CMT devices".

This patch reworks the DT binding documentation for the 6-channel
48-bit CMTs known as CMT1 on r8a7740 and sh73a0.

After the update the same style of DT binding as the rest of the upstream
SoCs will now also be used by r8a7740 and sh73a0. The DT binding "cmt-48"
is removed from the DT binding documentation, however software support for
this deprecated binding will still remain in the CMT driver for some time.

Document the on-chip CMT devices included in r8a7740 and sh73a0.

Included in this patch is DT binding documentation for 32-bit CMTs
CMT0, CMT2, CMT3 and CMT4. They all contain a single channel and are
quite similar however some minor differences still exist:
 - "Counter input clock" (clock input and on-device divider)
    One example is that RCLK 1/1 is supported by CMT2, CMT3 and CMT4.
 - "Wakeup request" (supported by CMT0 and CMT2)

Because of this one unique compat string per CMT device is selected.

6ed756aa01 remoteproc: Add a sysfs interface for name
This patch adds a sysfs interface that provides the name of the
remote processor to userspace. This allows the userspace to identify
a remote processor as the remoteproc devices themselves are created
based on probe order and can change from one boot to another or
at runtime.

The name is made available in debugfs originally, and is being
retained for now. This can be cleaned up after couple of releases
once users get familiar with the new interface.

146c3d3220 Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
 "A few fixes for x86:

   - Fix a boot regression caused by the recent bootparam sanitizing
     change, which escaped the attention of all people who reviewed that
     code.

   - Address a boot problem on machines with broken E820 tables caused
     by an underflow which ended up placing the trampoline start at
     physical address 0.

   - Handle machines which do not advertise a legacy timer of any form,
     but need calibration of the local APIC timer gracefully by making
     the calibration routine independent from the tick interrupt. Marked
     for stable as well as there seems to be quite some new laptops
     rolled out which expose this.

   - Clear the RDRAND CPUID bit on AMD family 15h and 16h CPUs which are
     affected by broken firmware which does not initialize RDRAND
     correctly after resume. Add a command line parameter to override
     this for machine which either do not use suspend/resume or have a
     fixed BIOS. Unfortunately there is no way to detect this on boot,
     so the only safe decision is to turn it off by default.

   - Prevent RFLAGS from being clobbers in CALL_NOSPEC on 32bit which
     caused fast KVM instruction emulation to break.

   - Explain the Intel CPU model naming convention so that the repeating
     discussions come to an end"

47e4937a4a erofs: move erofs out of staging
EROFS filesystem has been merged into linux-staging for a year.

EROFS is designed to be a better solution of saving extra storage
space with guaranteed end-to-end performance for read-only files
with the help of reduced metadata, fixed-sized output compression
and decompression inplace technologies.

In the past year, EROFS was greatly improved by many people as
a staging driver, self-tested, betaed by a large number of our
internal users, successfully applied to almost all in-service
HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable
enough to be moved out of staging.

EROFS is a self-contained filesystem driver. Although there are
still some TODOs to be more generic, we have a dedicated team
actively keeping on working on EROFS in order to make it better
with the evolution of Linux kernel as the other in-kernel filesystems.

As Pavel suggested, it's better to do as one commit since git
can do moves and all histories will be saved in this way.

Let's promote it from staging and enhance it more actively as
a "real" part of kernel for more wider scenarios!

5aba54302a f2fs: include charset encoding information in the superblock
Add charset encoding to f2fs to support casefolding. It is modeled after
the same feature introduced in commit c83ad55eaa ("ext4: include charset
encoding information in the superblock")

Currently this is not compatible with encryption, similar to the current
ext4 imlpementation. This will change in the future.

>From the ext4 patch:
"""
The s_encoding field stores a magic number indicating the encoding
format and version used globally by file and directory names in the
filesystem.  The s_encoding_flags defines policies for using the charset
encoding, like how to handle invalid sequences.  The magic number is
mapped to the exact charset table, but the mapping is specific to ext4.
Since we don't have any commitment to support old encodings, the only
encoding I am supporting right now is utf8-12.1.0.

The current implementation prevents the user from enabling encoding and
per-directory encryption on the same filesystem at the same time.  The
incompatibility between these features lies in how we do efficient
directory searches when we cannot be sure the encryption of the user
provided fname will match the actual hash stored in the disk without
decrypting every directory entry, because of normalization cases.  My
quickest solution is to simply block the concurrent use of these
features for now, and enable it later, once we have a better solution.
