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.

2c9d5b5e32 hwmon: Remove ads1015 driver
A driver for ADS1015 with more functionality is available in the iio
subsystem.

Remove the hwmon driver as duplicate. If the chip is used for hardware
monitoring, the iio->hwmon bridge should be used.

Note the binding is st,lsm9ds1-imu.  This device is effectively
two separate devices in the same package. (separate addreses,

as lsm9ds1-mag.  imu may not be the best name but it's the best

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.

96e46dcfb8 USB: Changes for v5.4 merge window
With only 45 non-merge commits, we have a small merge window from the
 Gadget perspective.
 
 The biggest change here is the addition of the Cadence USB3 DRD
 Driver. All other changes are small, non-critical fixes or smaller new
 features like the improvement to BESL handling in dwc3.

0642ea2409 ext4 crypto: fix to check feature status before get policy
When getting fscrypt policy via EXT4_IOC_GET_ENCRYPTION_POLICY, if
encryption feature is off, it's better to return EOPNOTSUPP instead of
ENODATA, so let's add ext4_has_feature_encrypt() to do the check for
that.

This makes it so that all fscrypt ioctls consistently check for the
encryption feature, and makes ext4 consistent with f2fs in this regard.

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
                           |
                          M4U

                       |        |
                       |        |
                   gals0-tx   gals1-tx
                       |        |
                      ------------
                       SMI Common
                      ------------
                           |
  +-----+-----+--------+-----+-----+-------+-------+
  |     |     |        |     |     |       |       |
  |     |  gals-rx  gals-rx  |   gals-rx gals-rx gals-rx
  |     |     |        |     |     |       |       |
  |     |     |        |     |     |       |       |
  |     |  gals-tx  gals-tx  |   gals-tx gals-tx gals-tx
  |     |     |        |     |     |       |       |
larb0 larb1  IPU0    IPU1  larb4  larb5  larb6    CCU
disp  vdec   img     cam    venc   img    cam

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.

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.

v2: Rebased on top of RQ_ALLOC_TIME changes and folded in Rik's fix
    for a divide-by-zero bug in current_hweight() triggered by zero

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.

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".

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!

051f8d2d86 media: docs-rst: Document memory-to-memory video decoder interface
Due to complexity of the video decoding process, the V4L2 drivers of
stateful decoder hardware require specific sequences of V4L2 API calls
to be followed. These include capability enumeration, initialization,
decoding, seek, pause, dynamic resolution change, drain and end of
stream.

Specifics of the above have been discussed during Media Workshops at
LinuxCon Europe 2012 in Barcelona and then later Embedded Linux
Conference Europe 2014 in Düsseldorf. The de facto Codec API that
originated at those events was later implemented by the drivers we already
have merged in mainline, such as s5p-mfc or coda.

The only thing missing was the real specification included as a part of
Linux Media documentation. Fix it now and document the decoder part of
the Codec API.

c49a0a8013 x86/CPU/AMD: Clear RDRAND CPUID bit on AMD family 15h/16h
There have been reports of RDRAND issues after resuming from suspend on
some AMD family 15h and family 16h systems. This issue stems from a BIOS
not performing the proper steps during resume to ensure RDRAND continues
to function properly.

RDRAND support is indicated by CPUID Fn00000001_ECX[30]. This bit can be
reset by clearing MSR C001_1004[62]. Any software that checks for RDRAND
support using CPUID, including the kernel, will believe that RDRAND is
not supported.

Update the CPU initialization to clear the RDRAND CPUID bit for any family
15h and 16h processor that supports RDRAND. If it is known that the family
15h or family 16h system does not have an RDRAND resume issue or that the
system will not be placed in suspend, the "rdrand=force" kernel parameter
can be used to stop the clearing of the RDRAND CPUID bit.

Additionally, update the suspend and resume path to save and restore the
MSR C001_1004 value to ensure that the RDRAND CPUID setting remains in
place after resuming from suspend.

Note, that clearing the RDRAND CPUID bit does not prevent a processor
that normally supports the RDRAND instruction from executing it. So any
code that determined the support based on family and model won't #UD.

Some stateful decoders are capable of fully parsing a bytestream,

If this flag is set, then this pre-parsing step is not required

life and build that list kernel-side (generic helpers will be provided
for drivers that need this list).

8cae93e090 media: uapi: h264: Add the concept of start code
Stateless decoders have different expectations about the
start code that is prepended on H264 slices. Add a
menu control to express the supported start code types
(including no start code).

Drivers are allowed to support only one start code type,
but they can support both too.

Note that this is independent of the H264 decoding mode,
which specifies the granularity of the decoding operations.
Either in frame-based or slice-based mode, this new control
will allow to define the start code expected on H264 slices.

5604be66a5 media: uapi: h264: Add the concept of decoding mode
Some stateless decoders don't support per-slice decoding granularity
(or at least not in a way that would make them efficient or easy to use).

Expose a menu to control the supported decoding modes. Drivers are
allowed to support only one decoding but they can support both too.

To fully specify the decoding operation, we need to introduce
a start_byte_offset, to indicate where slices start.

7bb3c32abd media: uapi: h264: Rename pixel format
The V4L2_PIX_FMT_H264_SLICE_RAW name was originally suggested
because the pixel format would represent H264 slices without any
start code.

However, as we will now introduce a start code menu control,
give the pixel format a more meaningful name, while it's
still early enough to do so.

df2474a22c locks: print a warning when mount fails due to lack of "mand" support
Since 9e8925b67a ("locks: Allow disabling mandatory locking at compile
time"), attempts to mount filesystems with "-o mand" will fail.
Unfortunately, there is no other indiciation of the reason for the
failure.

Change how the function is defined for better readability. When
CONFIG_MANDATORY_FILE_LOCKING is disabled, printk a warning when
someone attempts to mount with -o mand.

Also, add a blurb to the mandatory-locking.txt file to explain about
the "mand" option, and the behavior one should expect when it is
disabled.
