2ce7135adc psi: cgroup support 
On a system that executes multiple cgrouped jobs and independent
workloads, we don't just care about the health of the overall system, but
also that of individual jobs, so that we can ensure individual job health,
fairness between jobs, or prioritize some jobs over others.

This patch implements pressure stall tracking for cgroups.  In kernels
with CONFIG_PSI=y, cgroup2 groups will have cpu.pressure, memory.pressure,
and io.pressure files that track aggregate pressure stall times for only
the tasks inside the cgroup.

eb414681d5 psi: pressure stall information for CPU, memory, and IO 
When systems are overcommitted and resources become contended, it's hard
to tell exactly the impact this has on workload productivity, or how close
the system is to lockups and OOM kills.  In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency
and throughput on the individual job can be enormous.

In order to maximize hardware utilization without sacrificing individual
job health or risk complete machine lockups, this patch implements a way
to quantify resource pressure in the system.

A kernel built with CONFIG_PSI=y creates files in /proc/pressure/ that
expose the percentage of time the system is stalled on CPU, memory, or IO,
respectively.  Stall states are aggregate versions of the per-task delay
accounting delays:

       cpu: some tasks are runnable but not executing on a CPU
       memory: tasks are reclaiming, or waiting for swapin or thrashing cache
       io: tasks are waiting for io completions

These percentages of walltime can be thought of as pressure percentages,
and they give a general sense of system health and productivity loss
incurred by resource overcommit.  They can also indicate when the system
is approaching lockup scenarios and OOMs.

To do this, psi keeps track of the task states associated with each CPU
and samples the time they spend in stall states.  Every 2 seconds, the
samples are averaged across CPUs - weighted by the CPUs' non-idle time to
eliminate artifacts from unused CPUs - and translated into percentages of
walltime.  A running average of those percentages is maintained over 10s,
1m, and 5m periods (similar to the loadaverage).

61f94e18de mm, proc: add KReclaimable to /proc/meminfo 
The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab
allocations that can be reclaimed via shrinker.  In /proc/meminfo, we can
show the sum of all reclaimable kernel allocations (including slab) as
"KReclaimable".  Add the same counter also to per-node meminfo under /sys

With this counter, users will have more complete information about kernel
memory usage.  Non-slab reclaimable pages (currently just the ION
allocator) will not be missing from /proc/meminfo, making users wonder
where part of their memory went.  More precisely, they already appear in
MemAvailable, but without the new counter, it's not obvious why the value
in MemAvailable doesn't fully correspond with the sum of other counters
participating in it.

c5fd3ca06b slub: extend slub debug to handle multiple slabs 
Extend the slub_debug syntax to "slub_debug=<flags>[,<slub>]*", where
<slub> may contain an asterisk at the end.  For example, the following
would poison all kmalloc slabs:

	slub_debug=P,kmalloc*

and the following would apply the default flags to all kmalloc and all
block IO slabs:

	slub_debug=,bio*,kmalloc*

Please note that a similar patch was posted by Iliyan Malchev some time
ago but was never merged:

3acbd2de6b sound updates for 4.20 
There have been little changes in ALSA core stuff, but ASoC core still
 kept rolling for the continued restructuring.  The rest are lots of
 small driver-specific changes and some minor API updates.
 Here are highlights:
 
 General:
 - Appropriate fall-through annotations everywhere
 - Some code cleanup in memalloc code, handling non-cacahed pages more
   commonly in the helper
 - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
 
 Drivers:
 - More HD-audio CA0132 codec improvement for supporting other Creative
   boards
 - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
   give move support of existing HD-audio devices with DSP
 - A few device-specific HD-audio quirks as usual
 - New quirk for RME CC devices and correction for B&W PX for USB-audio
 - FireWire: code refactoring including devres usages
 
 ASoC Core:
 - Continued componentization works; it's almost done!
 - A bunch of new for_each_foo macros
 - Cleanups and fixes in DAPM code
 
 ASoC Drivers:
 - MCLK support for several different devices, including CS42L51, STM32
   SAI, and MAX98373
 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
   MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
   TI PCM3060

This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
 qla2xxx, lpfc, libsas, hisi_sas.  In addition there's a set of mostly
 small updates to the target subsystem a set of conversions to the
 generic DMA API, which do have some potential for issues in the older
 drivers but we'll handle those as case by case fixes. A new myrs for
 the DAC960/mylex raid controllers to replace the block based DAC960
 which is also being removed by Jens in this merge window. Plus the

readability improvements for the formatted output, some LICENSES updates
 including the addition of the ISC license, the removal of the unloved and

d6edff78fe f2fs-for-4.20-rc1 
In this round, we've added 1) superblock checksum feature, 2) implemented new
 mount option which we can disable/enable checkpoint to provide atomic updates of
 entire filesystem, 3) refactored quota operations to enhance its consistency
 along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward
 recovery flow to resurrect any fsync'ed inode metadata.
 
 Enhancement:
  - add checksum to keep superblock contents more safe
  - add checkpoint=disable/enable to support A/B update of entire filesystem
  - use plug for readahead IO in readdir
  - add more IO counts to avoid block layer hacks
 
 Bug fix:
  - prevent data corruption issue for hardware encryption
  - fix IO hang issues when GC is heavily triggered
  - add missing up_read in __write_node_page
  - recover inode metadata during roll-forward recovery flow
  - fix null pointer dereference issue in wrongly configured discard map
 
 There are some more sanity checks and minor bug fixes as well.

security embargoes. This is incorrect, and could dissuade people from
reporting security issues to us under the false assumption that the
issue would leak prematurely.

Clarify the handling of embargoed information in our process

Pull RCU updates from Ingo Molnar:
 "The biggest change in this cycle is the conclusion of the big
  'simplify RCU to two primary flavors' consolidation work - i.e.
  there's a single RCU flavor for any kernel variant (PREEMPT and
  !PREEMPT):

    - Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into a
      single flavor similar to RCU-sched in !PREEMPT kernels and into a
      single flavor similar to RCU-preempt (but also waiting on
      preempt-disabled sequences of code) in PREEMPT kernels.

      This branch also includes a refactoring of
      rcu_{nmi,irq}_{enter,exit}() from Byungchul Park.

    - Now that there is only one RCU flavor in any given running kernel,
      the many "rsp" pointers are no longer required, and this cleanup
      series removes them.

    - This branch carries out additional cleanups made possible by the
      RCU flavor consolidation, including inlining now-trivial
      functions, updating comments and definitions, and removing
      now-unneeded rcutorture scenarios.

    - Now that there is only one flavor of RCU in any running kernel,
      there is also only on rcu_data structure per CPU. This means that
      the rcu_dynticks structure can be merged into the rcu_data
      structure, a task taken on by this branch. This branch also
      contains a -rt-related fix from Mike Galbraith.

  There were also other updates:

    - Documentation updates, including some good-eye catches from Joel
      Fernandes.

    - SRCU updates, most notably changes enabling call_srcu() to be
      invoked very early in the boot sequence.

    - Torture-test updates, including some preliminary work towards
      making rcutorture better able to find problems that result in
      insufficient grace-period forward progress.

    - Initial changes to RCU to better promote forward progress of grace
      periods, including fixing a bug found by Marius Hillenbrand and
      David Woodhouse, with the fix suggested by Peter Zijlstra"

114b5f8f7e This is the bulk of GPIO changes for the v4.20 series: 
Core changes:
 
 - A patch series from Hans Verkuil to make it possible to
   enable/disable IRQs on a GPIO line at runtime and drive GPIO
   lines as output without having to put/get them from scratch.
   The irqchip callbacks have been improved so that they can
   use only the fastpatch callbacks to enable/disable irqs
   like any normal irqchip, especially the gpiod_lock_as_irq()
   has been improved to be callable in fastpath context.
   A bunch of rework had to be done to achieve this but it is
   a big win since I never liked to restrict this to slowpath.
   The only call requireing slowpath was try_module_get() and
   this is kept at the .request_resources() slowpath callback.
   In the GPIO CEC driver this is a big win sine a single
   line is used for both outgoing and incoming traffic, and
   this needs to use IRQs for incoming traffic while actively
   driving the line for outgoing traffic.
 
 - Janusz Krzysztofik improved the GPIO array API to pass a
   "cookie" (struct gpio_array) and a bitmap for setting or
   getting multiple GPIO lines at once. This improvement
   orginated in a specific need to speed up an OMAP1 driver and
   has led to a much better API and real performance gains
   when the state of the array can be used to bypass a lot
   of checks and code when we want things to go really fast.
   The previous code would minimize the number of calls
   down to the driver callbacks assuming the CPU speed was
   orders of magnitude faster than the I/O latency, but this
   assumption was wrong on several platforms: what we needed
   to do was to profile and improve the speed on the hot
   path of the array functions and this change is now
   completed.
 
 - Clean out the painful and hard to grasp BNF experiments
   from the device tree bindings. Future approaches are looking
   into using JSON schema for this purpose. (Rob Herring
   is floating a patch series.)
 
 New drivers:
 
 - The RCAR driver now supports r8a774a1 (RZ/G2M).
 
 - Synopsys GPIO via CREGs driver.
 
 Major improvements:
 
 - Modernization of the EP93xx driver to use irqdomain and
   other contemporary concepts.
 
 - The ingenic driver has been merged into the Ingenic pin
   control driver and removed from the GPIO subsystem.
 
 - Debounce support in the ftgpio010 driver.

ca9eb48fe0 regulator: Regulator updates for next release 
The biggest chunk of the regulator changes for this release outside of
 the new drivers is the conversion of the fixed regulator to use the GPIO
 descriptor API, there's a small addition to the GPIO API plus a bunch of
 updates to board files to implement it.  This is some really welcome
 work from Linus Walleij that's had a bunch of review and has been
 sitting in -next for a while so I'm fairly happy there's no major
 issues.
 
  - Helpers for overlapping linear ranges.
  - Display opmode and consumer requested load in the regualtor_summary
    file in debugfs, plus a fix there.
  - Support for the fun and entertaining power off mechanism that the
    pfuze100 hardware implements.
  - Conversion of the fixed regulator API to use GPIO descriptors,
    including pulling in a bunch of patches to a bunch of board files.
  - New drivers for Cirrus Logic Lochnagar, Qualcomm PMS405, Rohm
    BD71847, ST PMIC1, and TI LM363x devices.

        (internals), in platform drivers, etc.
      * Functions/structures reordering.
      * Exclusive use of the nand_chip structure instead of the MTD one
        all across the subsystem.
   - Addition of the nand_wait_readrdy/rdy_op() helpers.

 Raw NAND controllers drivers changes:
   - Various coccinelle patches.
   - Marvell:
      * Use regmap_update_bits() for syscon access.
      * More documentation.
      * BCH failure path rework.
      * More layouts to be supported.
      * IRQ handler complete() condition fixed.

      * Fix licenses mismatch and use a SPDX tag.
      * Set SPARE_AREA_SKIP_BYTES register to 8 if unset.
   - Qualcomm:
      * Do not include dma-direct.h.
   - Docg4:
      * Removed.
   - Ams-delta:
      * Use of a GPIO lookup table
      * Internal machinery changes.

 Raw NAND chip drivers changes:
   - Toshiba:
      * Add support for Toshiba memory BENAND
      * Pass a single nand_chip object to the status helper.

Takashi Iwai
5e3cdecf78 ASoC: Updates for v5.0/v4.20 
As ever there's a lot of small and driver specific changes going on
 here, but we do also have some relatively large changes in the core
 thanks to the hard work of Charles and Morimoto-san:
 
  - More component transitions from Morimoto-san, I think we're about
    finished with this.  Thanks for all the hard work!
  - Morimoto-san also added a bunch of for_each_foo macros
  - A bunch of cleanups and fixes for DAPM from Charles.
  - MCLK support for several different devices, including CS42L51, STM32
    SAI, and MAX98373.
  - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
    MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
    TI PCM3060.
