7d9d077c78 RCU pull request for v5.20 (or whatever) 
This pull request contains the following branches:
 
 doc.2022.06.21a: Documentation updates.
 
 fixes.2022.07.19a: Miscellaneous fixes.
 
 nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new
 	RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to
 	be offloaded at boot time, regardless of kernel boot parameters.
 	This is useful to battery-powered systems such as ChromeOS
 	and Android.  In addition, a new RCU_NOCB_CPU_CB_BOOST kernel
 	boot parameter prevents offloaded callbacks from interfering
 	with real-time workloads and with energy-efficiency mechanisms.
 
 poll.2022.07.21a: Polled grace-period updates, perhaps most notably
 	making these APIs account for both normal and expedited grace
 	periods.
 
 rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing
 	the CPU overhead of RCU tasks trace grace periods by more than
 	a factor of two on a system with 15,000 tasks.	The reduction
 	is expected to increase with the number of tasks, so it seems
 	reasonable to hypothesize that a system with 150,000 tasks might
 	see a 20-fold reduction in CPU overhead.
 
 torture.2022.06.21a: Torture-test updates.
 
 ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into
 	context tracking, thus reducing the overhead of transitioning to
 	kernel mode from either idle or nohz_full userspace execution
 	for kernels that track context independently of RCU.  This is
 	expected to be helpful primarily for kernels built with
 	CONFIG_NO_HZ_FULL=y.

Merge tag 'for-5.20/io_uring-2022-07-29' of git://git.kernel.dk/linux-block

Pull io_uring updates from Jens Axboe:

 - As per (valid) complaint in the last merge window, fs/io_uring.c has
   grown quite large these days. io_uring isn't really tied to fs
   either, as it supports a wide variety of functionality outside of
   that.

   Move the code to io_uring/ and split it into files that either
   implement a specific request type, and split some code into helpers
   as well. The code is organized a lot better like this, and io_uring.c
   is now < 4K LOC (me).

 - Deprecate the epoll_ctl opcode. It'll still work, just trigger a
   warning once if used. If we don't get any complaints on this, and I
   don't expect any, then we can fully remove it in a future release
   (me).

 - Improve the cancel hash locking (Hao)

 - kbuf cleanups (Hao)

 - Efficiency improvements to the task_work handling (Dylan, Pavel)

 - Provided buffer improvements (Dylan)

 - Add support for recv/recvmsg multishot support. This is similar to
   the accept (or poll) support for have for multishot, where a single
   SQE can trigger everytime data is received. For applications that
   expect to do more than a few receives on an instantiated socket, this
   greatly improves efficiency (Dylan).

 - Efficiency improvements for poll handling (Pavel)

 - Poll cancelation improvements (Pavel)

 - Allow specifiying a range for direct descriptor allocations (Pavel)

 - Cleanup the cqe32 handling (Pavel)

 - Move io_uring types to greatly cleanup the tracing (Pavel)

 - Tons of great code cleanups and improvements (Pavel)

 - Add a way to do sync cancelations rather than through the sqe -> cqe
   interface, as that's a lot easier to use for some use cases (me).

 - Add support to IORING_OP_MSG_RING for sending direct descriptors to a
   different ring. This avoids the usually problematic SCM case, as we
   disallow those. (me)

 - Make the per-command alloc cache we use for apoll generic, place
   limits on it, and use it for netmsg as well (me).

 - Various cleanups (me, Michal, Gustavo, Uros)

c1dbe9a1c8 Thermal control updates for 5.20-rc1 
- Consolidate the thermal core code by beginning to move the thermal
    trip structure from the thermal OF code as a generic structure to be
    used by the different sensors when registering a thermal zone
    (Daniel Lezcano).
 
  - Make per cpufreq / devfreq cooling device ops instead of using a
    global variable, fix comments and rework the trace information
    (Lukasz Luba).
 
  - Add the include/dt-bindings/thermal.h under the area covered by the
    thermal maintainer in the MAINTAINERS file (Lukas Bulwahn).
 
  - Improve the error output by giving the sensor identification when a
    thermal zone failed to initialize, the DT bindings by changing the
    positive logic and adding the r8a779f0 support on the rcar3 (Wolfram
    Sang).
 
  - Convert the QCom tsens DT binding to the dtsformat format (Krzysztof
    Kozlowski).
 
  - Remove the pointless get_trend() function in the QCom, Ux500 and

 Some existing drivers get improvements and broader chip support and a

The big update this time around is some excellent work from David Jander
 who went through the fast path and really eliminated overheads, meaning
 that we are seeing a huge reduction in the time spent between transfers
 for single threaded clients. Benchmarking has been coming out at about a
 halving of overhead which is clearly visible in system level usage that
 stresses SPI like some CAN and IIO applications, especially with small
 transfers. Thanks to David for taking the time to drill down into this
 and push the work upstream.
 
 Otherwise there's been a bunch of new device support and the usual
 
  - Optimisation of the fast path, particularly around the number and
    types of locking operations, from David Jander.

dd65b96492 ARM: new SoC support for 6.0 
This adds initial support for two SoC families that have been under
 review for a while. In both cases, the origonal idea was to have a
 minimally functional version, but we ended up leaving out the clk drivers
 that are still under review and will be merged through the corresponding
 subsystem tree.
 
 The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and
 based on the 32-bit NPCM7xx family but is now getting added to
 arch/arm64 as well.
 
 Sunplus SP7021, also known as Plus1, is a general-purpose
 System-in-Package design based on the 32-bit Cortex-A7 SoC
 on the main chip, plus an I/O chip and memory in the same

3976d758e0 ARM: DT changes for 6.0 
As usual, the bulk of the changes for the SoC tree are devicetree file
 updates, and most of these changes are for 64-bit embedded machines.
 As before, there are a ton of style cleanups, and additional hardware
 support for existing machines.
 
 Looking only at the new SoC, the notable additions are:
 
  - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
    BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
    BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
    Each SoC comes with a corresponding reference board.
 
  - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
    i.MX8 embedded SoCs, now using Cortex-A55 cores and the
    Ethos-U65 NPU.
 
  - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
    of Arm based Laptop SoCs, and its automotive cousin, the
    SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
    laptop that also gets added here in addition to the reference
    boards.
 
  - Allwinner H616, a newer version of the H6 SoC, targeted at
    Set-top-box applications. It comes with dts files for the
    Orange Pi zero2 single-board computer and the X96 Mate
    set-top-box
 
  - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
    in the Armada SoC family based on the Cortex-A55 core.
 
 New machines based on previously supported SoCs include:
 
  - Several new machines on NXP i.MX platforms: multiple Toradex
    Colibri boards using the "Iris" and "Ixora" carriers,
    DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
    TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
 
  - Google Chameleon v3 FPGA board based on Intel Arria10 and
    Stratix 10 Software Virtual platform, both in the SoCFPGA
    platform.
 
  - Two new wireless devices based on Broadcom SoCs:
    The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
 
  - Improved Chromebook support for both the Mediatek and Qualcomm
    SoC families brought added machines: Acer Chromebook 514 (MT8192),
    Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
    machines including the Lenovo IdeaPad Chromebook Duet 3.
 
  - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
    Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
 
  - Finally, there are a few development board on other chips:
    PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
    DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm
    SDM660)

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
 "Highlights include a major rework of our kPTI page-table rewriting
  code (which makes it both more maintainable and considerably faster in
  the cases where it is required) as well as significant changes to our
  early boot code to reduce the need for data cache maintenance and
  greatly simplify the KASLR relocation dance.

  Summary:

   - Remove unused generic cpuidle support (replaced by PSCI version)

   - Fix documentation describing the kernel virtual address space

   - Handling of some new CPU errata in Arm implementations

   - Rework of our exception table code in preparation for handling
     machine checks (i.e. RAS errors) more gracefully

   - Switch over to the generic implementation of ioremap()

   - Fix lockdep tracking in NMI context

   - Instrument our memory barrier macros for KCSAN

   - Rework of the kPTI G->nG page-table repainting so that the MMU
     remains enabled and the boot time is no longer slowed to a crawl
     for systems which require the late remapping

   - Enable support for direct swapping of 2MiB transparent huge-pages
     on systems without MTE

   - Fix handling of MTE tags with allocating new pages with HW KASAN

   - Expose the SMIDR register to userspace via sysfs

   - Continued rework of the stack unwinder, particularly improving the
     behaviour under KASAN

   - More repainting of our system register definitions to match the
     architectural terminology

   - Improvements to the layout of the vDSO objects

   - Support for allocating additional bits of HWCAP2 and exposing
     FEAT_EBF16 to userspace on CPUs that support it

   - Considerable rework and optimisation of our early boot code to
     reduce the need for cache maintenance and avoid jumping in and out
     of the kernel when handling relocation under KASLR

   - Support for disabling SVE and SME support on the kernel
     command-line

   - Support for the Hisilicon HNS3 PMU

   - Miscellanous cleanups, trivial updates and minor fixes"

Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull acl updates from Christian Brauner:
 "Last cycle we introduced support for mounting overlayfs on top of
  idmapped mounts. While looking into additional testing we realized
  that posix acls don't really work correctly with stacking filesystems
  on top of idmapped layers.

  We already knew what the fix were but it would require work that is
  more suitable for the merge window so we turned off posix acls for
  v5.19 for overlayfs on top of idmapped layers with Miklos routing my
  patch upstream in 72a8e05d4f ("Merge tag 'ovl-fixes-5.19-rc7' [..]").

  This contains the work to support posix acls for overlayfs on top of
  idmapped layers. Since the posix acl fixes should use the new
  vfs{g,u}id_t work the associated branch has been merged in. (We sent a
  pull request for this earlier.)

  We've also pulled in Miklos pull request containing my patch to turn
  of posix acls on top of idmapped layers. This allowed us to avoid
  rebasing the branch which we didn't like because we were already at
  rc7 by then. Merging it in allows this branch to first fix posix acls
  and then to cleanly revert the temporary fix it brought in by commit
  4a47c6385b ("ovl: turn of SB_POSIXACL with idmapped layers
  temporarily").

  The last patch in this series adds Seth Forshee as a co-maintainer for
  idmapped mounts. Seth has been integral to all of this work and is
  also the main architect behind the filesystem idmapping work which
  ultimately made filesystems such as FUSE and overlayfs available in
  containers. He continues to be active in both development and review.
  I'm very happy he decided to help and he has my full trust. This
  increases the bus factor which is always great for work like this. I'm
  honestly very excited about this because I think in general we don't
  do great in the bringing on new maintainers department"

Merge the new SoC support from Tomer Maimon:
 "This patchset  adds initial support for the Nuvoton
  Arbel NPCM8XX Board Management controller (BMC) SoC family.

  The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC.
  The NPCM8XX computing subsystem comprises a quadcore ARM
  Cortex A35 ARM-V8 architecture.

  This patchset adds minimal architecture and drivers such as:
  Clocksource, Clock, Reset, and WD.

  Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX.

  This patchset was tested on the Arbel NPCM8XX evaluation board."

I'm leaving out the clk controller driver, which is still under
review.

b2111a01dc Update devfreq next for v5.20 
Detailed description for this pull request:
 1. Add new Mediatek CCI (Cache Coherent Interconnect) devfreq driver
 - Add new MediaTek Cache Coherent Interconnect (CCI) devfreq drviver
   which supports the dynamic voltage and clock scaling.
   This driver uses the passive devfreq governor to get target frequencies
   and adjust voltages because it depends on MediaTek cpu frequency
   driver. In MT8183 and MT8186, the MediaTek CCI is supplied
   by the same regulators with the little core CPUs.
 
 2. Update the devfreq drivers
 - Convert the Samsung Exynos SoC Bus bindings to DT schema of exynos-bus.c
 
 - Remove kernel-doc warnings by adding the description for unused
   fucntio parameters on devfreq core.
 
 - Use NULL to pass a null pointer rather than zero according to function
   propotype on imx-bus.c
 
 - Print error message instead of error interger value on tegra30-devfreq.c

Most of the contents are bugfixes for the devicetree files:
 
  - A Qualcomm MSM8974 pin controller regression, caused by a cleanup
    patch that gets partially reverted here.
 
  - Missing properties for Broadcom BCM49xx to fix timer detection and
    SMP boot.
 
  - Fix touchscreen pinctrl for imx6ull-colibri board
 
  - Multiple fixes for Rockchip rk3399 based machines including the
    vdu clock-rate fix, otg port fix on Quartz64-A and ethernet
    on Quartz64-B
 
  - Fixes for misspelled DT contents causing minor problems on
    imx6qdl-ts7970m, orangepi-zero, sama5d2, kontron-kswitch-d10,
    and ls1028a
 
 And a couple of changes elsewhere:
 
  - Fix binding for Allwinner D1 display pipeline
 
  - Trivial code fixes to the TEE and reset controller driver subsystems
    and the rockchip platform code.
 
  - Multiple updates to the MAINTAINERS files, marking the Palm Treo
    support as orphaned, and fixing some entries for added or changed
    file names.

 "Including fixes from netfilter, bpf and wireless.

  Still no major regressions, the release continues to be calm. An
  uptick of fixes this time around due to trivial data race fixes and
  patches flowing down from subtrees.

  There has been a few driver fixes (particularly a few fixes for false
  positives due to 66e4c8d950 which went into -next in May!) that make
  me worry the wide testing is not exactly fully through.

  So "calm" but not "let's just cut the final ASAP" vibes over here.

e0a5925055 Qualcomm ARM64 DTS updates for v5.20 
This introduces initial support for Lenovo ThinkPad X13s, Qualcomm 8cx
 Gen 3 Compute Reference Device, SA8295P Automotive Development Platform,
 Xiaomi Mi 5s Plus, five new SC7180 Chrome OS boards, Inforce IFC6560, LG
 G7 ThinQ and LG V35 ThinQ.
 
 With IPQ8074 gaining GDSC support, this was expressed in the gcc node
 and defined for the USB nodes. The SDHCI reset line was defined to get
 the storage devices into a known state.
 
 For MSM8996 interconnect providers, the second DSI interface, resets for
 SDHCI are introduced. Support for the Xiaomi Mi 5s Plus is introduced
 and the Dragonboard 820c gains definitions for its LEDs.
 
 The MSM8998 platform changes consists of a various cleanup patches, the
 FxTec Pro1 is split out from using the MTP dts and Sony Xperia devices
 on the "Yoshino" platform gains ToF sensor.
 
 On SC7180 five new Trogdor based boards are added and the description of
 keyboard and detachables is improved.
 
 On the SC7280-based Herobrine board DisplayPort is enabled, SPI flash
 clock rate is changed, WiFi is enabled and the modem firmware path is
 updated. The Villager boards gains touchscreen, and keyboard backlight.
 
 This introduces initial support for the SC8280XP (aka 8cx Gen 3) and
 related automotive platforms are introduced, with support for the
 Qualcomm reference board, the Lenovo Thinkpad X13s and the SA8295P
 Automotive Development Platform.
 
 In addition to a wide range of smaller fixes on the SDM630 and SDM660
 platforms, support for the secondary high speed USB controller is
 introduced and the Sony Xperia "Nile" platform gains support for the RGB
 status LED. Support for the Inforce IFC6560 board is introduced.
 
 On SDM845 the bandwidth monitor for the CPU subsystem is introduced, to
 scale LLCC clock rate based on profiling. CPU and cluster idle states
 are switched to OSI hierarchical states. DB845c and SHIFT 6mq gains LED
 support and new support for the LG G7 ThinQ and LG V35 ThinQ boards are
 added.
 
 DLL/DDR configuration for SDHCI nodes are defined for SM6125.
 
 On SM8250 the GPU per-process page tables is enabled and for RB5 the
 Light Pulse Generator-based LEDs are added.
 
 The display clock controller is introduced for SM8350.
 
 On SM8450 this introduces the camera clock controller and the UART
 typically used for Bluetooth. The interconnect path for the crypto
 engine is added to the SCM node, to ensure this is adequately clocked.
 
 The assigned-clock-rate for the display processor is dropped from
 several platforms, now that the driver derrives the min and max from the
 clock.
 
 In addition to this a wide range of fixes for stylistic issues and
 issues discovered through Devicetree binding validation across many
 platforms and boards are introduced.

3c37074f0d Qualcomm driver updates for v5.20 
This introduces a new driver that requests interconnect bandwidth based
 on throughput measurements of the bwmon hardware blocks found associated
 with, among other things, the CPU subsystem on many Qualcomm platforms.
 
 It introduces support for the SCM wrapper driver to vote for
 interconnect bandwidth for operations that needs bandwidth to the crypto
 engine. This ensures both performance and guards against issues caused
 by lacking votes for this path.
 
 The socinfo driver gains knowledge about the SC7180P SoC.
 
 It contains a range of fixes for spelling mistakes, refcount leaks in
 various drivers and removes some redundant code from the apr remove
 path.
 
 The SCM DT bindings are updated to declare support for QCS404, SM6125
 and SDX65.
 
 The command db driver has a strncpy() converted to strscpy_pad() and
 then back again with proper documentation to why this was the right API.

ed56f4b517 MAINTAINERS: update the LSM maintainer info 
After many years of shepherding the LSM layer, and Linux kernel
access control in general, James has decided to take a small step
away from his technical role and has asked me to assume the
day-to-day maintenance tasks for the LSM.  This patch makes the
necessary updates to the MAINTAINERS file.

Thanks for all you patience and stewardship over the years James,
I promise to do my best not to screw it all up :)
