Linus Torvalds 1d8ce0e093 This is the bulk of GPIO changes for the v5.9 kernel cycle:
Core changes:
 
 - Introduce the for_each_requested_gpio() macro to help in
   dependent code all over the place. Also patch a few locations
   to use it while we are at it.
 
 - Split out the sysfs code into its own file.
 
 - Split out the character device code into its own file, then
   make a set of refactorings and improvements to this code.
   We are setting the stage to revamp the userspace API a bit
   in the next cycle.
 
 - Fix a whole slew of kerneldoc that was wrong or missing.
 
 New drivers:
 
 - The PCA953x driver now supports the PCAL9535.
 
 Driver improvements:
 
 - A host of incremental modernizations and improvements to the
   PCA953x driver.
 
 - Incremental improvements to the Xilinx Zynq driver.
 
 - Some improvements to the GPIO aggregator driver.
 
 - I ran all over the place switching all threaded and other
   drivers requesting their own IRQ while using the core
   GPIO IRQ helpers to pass the GPIO irq chip as a template
   instead of calling the explicit set-up functions. Next merge
   window we may retire the old code altogether.

Linus Torvalds dd27111e32 Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
 using the changes, for 5.9-rc1.
 
 "Biggest" thing in here is the device link exposure in sysfs, to help
 to tame the madness that is SoC device tree representations and driver
 interactions with it.
 
 Other stuff in here that is interesting is:
 	- device probe log helper so that drivers can report problems in
 	  a unified way easier.
 	- devres functions added
 	- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
 	  incorrect sysfs file permissions
 	- documentation cleanups
 	- ability for debugfs to be present in the kernel, yet not
 	  exposed to userspace.  Needed for systems that want it
 	  enabled, but do not trust users, so they can still use some
 	  kernel functions that were otherwise disabled.
 	- other minor fixes and cleanups
 
 The patches outside of drivers/base/ all have acks from the respective
 subsystem maintainers to go through this tree instead of theirs.
 
 All of these have been in linux-next with no reported issues.

Tero Kristo cef9572e9a watchdog: add support for adjusting last known HW keepalive time
Certain watchdogs require the watchdog only to be pinged within a
specific time window, pinging too early or too late cause the watchdog
to fire. In cases where this sort of watchdog has been started before
kernel comes up, we must adjust the watchdog keepalive window to match
the actually running timer, so add a new driver API for this purpose.

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:

Ahmad Fatoum d51d3852d1 docs: watchdog: codify ident.options as superset of possible status flags
The FIXME comment has been in-tree since the very first git commit.
The described behavior has been since relied on by some userspace, e.g.
the util-linux wdctl command and has been ignored by some kernelspace,
like the f71808e_wdt driver.

The functionality is useful to have to be able to differentiate between a
driver that doesn't support WDIOF_CARDRESET and one that does, but hasn't
had a watchdog reset, thus drop the FIXME to encourage drivers adopting
this convention.

Codrin Ciubotariu db36e827d8 dt-bindings: i2c: add generic properties for GPIO bus recovery
The I2C GPIO bus recovery properties consist of two GPIOS and one extra
pinctrl state ("gpio" or "recovery"). "recovery" pinctrl state is
considered deprecated and "gpio" should be used instead.
Not all are mandatory for recovery.

Linus Torvalds 2324d50d05 It's been a busy cycle for documentation - hopefully the busiest for a
while to come.  Changes include:
 
  - Some new Chinese translations
 
  - Progress on the battle against double words words and non-HTTPS URLs
 
  - Some block-mq documentation
 
  - More RST conversions from Mauro.  At this point, that task is
    essentially complete, so we shouldn't see this kind of churn again for a
    while.  Unless we decide to switch to asciidoc or something...:)
 
  - Lots of typo fixes, warning fixes, and more.

Linus Torvalds 4da9f33026 Support for FSGSBASE. Almost 5 years after the first RFC to support it,
this has been brought into a shape which is maintainable and actually
 works.
 
 This final version was done by Sasha Levin who took it up after Intel
 dropped the ball. Sasha discovered that the SGX (sic!) offerings out there
 ship rogue kernel modules enabling FSGSBASE behind the kernels back which
 opens an instantanious unpriviledged root hole.
 
 The FSGSBASE instructions provide a considerable speedup of the context
 switch path and enable user space to write GSBASE without kernel
 interaction. This enablement requires careful handling of the exception
 entries which go through the paranoid entry path as they cannot longer rely
 on the assumption that user GSBASE is positive (as enforced via prctl() on
 non FSGSBASE enabled systemn). All other entries (syscalls, interrupts and
 exceptions) can still just utilize SWAPGS unconditionally when the entry
 comes from user space. Converting these entries to use FSGSBASE has no
 benefit as SWAPGS is only marginally slower than WRGSBASE and locating and
 retrieving the kernel GSBASE value is not a free operation either. The real
 benefit of RD/WRGSBASE is the avoidance of the MSR reads and writes.
 
 The changes come with appropriate selftests and have held up in field
 testing against the (sanitized) Graphene-SGX driver.

David S. Miller cabf06e5a2 wireless-drivers-next patches for v5.9
Second set of patches for v5.9. mt76 has most of patches this time.
 Otherwise it's just smaller fixes and cleanups to other drivers.
 
 There was a major conflict in mt76 driver between wireless-drivers and
 wireless-drivers-next. I solved that by merging the former to the
 latter.
 
 Major changes:
 
 rtw88
 
 * add support for ieee80211_ops::change_interface
 
 * add support for enabling and disabling beacon
 
 * add debugfs file for testing h2c
 
 mt76
 
 * ARP filter offload for 7663
 
 * runtime power management for 7663
 
 * testmode support for mfg calibration
 
 * support for more channels

Linus Torvalds 2baa85d692 ACPI updates for 5.9-rc1
- Eliminate significant AML processing overhead related to using
    operation regions in system memory by reworking the management
    of memory mappings in the ACPI code to defer unmap operations
    (to do them outside of the ACPICA locks, among other things) and
    making the memory operation reagion handler avoid releasing memory
    mappings created by it too early (Rafael Wysocki).
 
  - Update the ACPICA code in the kernel to upstream revision
    20200717:
 
    * Prevent operation region reference counts from overflowing in
      some cases (Erik Kaneda).
 
    * Replace one-element array with flexible-array (Gustavo A. R.
      Silva).
 
  - Fix ACPI PCI hotplug reference counting (Rafael Wysocki).
 
  - Drop last bits of the ACPI procfs interface (Thomas Renninger).
 
  - Drop some redundant checks from the code parsing ACPI tables
    related to NUMA (Hanjun Guo).
 
  - Avoid redundant object evaluation in the ACPI device properties
    handling code (Heikki Krogerus).
 
  - Avoid unecessary memory overhead related to storing the signatures
    of the ACPI tables recognized by the kernel (Ard Biesheuvel).
 
  - Add missing newline characters when printing module parameter
    values in some places (Xiongfeng Wang).
 
  - Update the link to the ACPI specifications in some places (Tiezhu
    Yang).
 
  - Use the fallthrough pseudo-keyword in the ACPI code (Gustavo A. R.
    Silva).
 
  - Drop redundant variable initialization from the APEI code (Colin

Linus Torvalds b171373902 spi: Updates for v5.9
A fairly quiet release for SPI, nothing really going on in the core
 although there's been quite a bit of driver related activity.  This pull
 request includes the addition of some shared code in drivers/memory for
 the Renesas RPC-IF which is used by a newly added SPI driver, the memory
 subsystem doesn't seem to have a fixed maintainer at the minute and this
 seemed like the most sensible way to get that hardware supported.
 
  - Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
    sun6i and lantiq drivers.
  - Several more GPIO descriptor conversions.
  - Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
  - New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
    R8A774e1.

This time around the bulk of the work on the regulator API has been
 cleanups of various kinds, partly but not entirely inspired by the W=1
 stuff that 0day turned on.  There's also been a fairly large crop of new
 drivers, and a few bugfixes for existing drivers.
 
  - Mode setting support for MT6397 and DA9211.
  - New drivers for ChromeOS embedded controllers, Fairchild FAN53880,

Linus Torvalds d4db4e5532 ARM: new SoC support for v5.9
There are three SoC families newly dded to the 32-bit and
 64-bit Arm architecture code in the kernel this time:
 
  - Daniel Palmer adds initial support for two chips made by MStar, a
    taiwanese SoC manufacturer that became part of Mediatek in 2012. For
    now, the added support is fairly minimal, with just two of its
    Cortex-A7 based 32-bit camera chips getting support for a limited
    set of on-chip peripherals.
 
  - Lars Povlsen from Microchip adds support for their new Sparx5
    family of ethernet switch chips using 64-bit Cortex-A53 cores.
    These are descended from earlier VSC7xxx SparX and Ocelot chips
    using 32-bit MIPS cores.
 
  - Daniele Alessandrelli from Intel adds support for the new Keem Bay
    SoC for computer vision, built around a Movidius VPU with Linux
    running on Arm Cortex-A53 cores.

Linus Torvalds 822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for

Linus Torvalds 2f3fbfdaf7 ARM: SoC DT changes for 5.9
As usual, there are many patches addressing minor issues in existing
 DTS files, such as DTC warnings, or adding support for additional
 peripherals.
 
 There are three added SoCs in existing product families:
 
  - Amazon:
     Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
     otherwise known as AL73400 or first-generation Graviton, and following
     the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips.
     This one is added together with the official Evaluation platform.
 
  - Qualcomm:
     The Snapdragon SDM630 platform is a family of mid-range mobile phone
     chips from 2017 based on Cortex-A53 or Kryo 260 CPUs.
     A total of five end-user products are added based on these, all
     Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and
     XA2 Ultra.
 
  - Renesas:
     RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
     family, and apparently closely related to the RZ/G2N and RZ/G2M
     models we already support but has a faster GPU and additional
     on-chip peripherals.
     It is added along with the HopeRun HiHope RZ/G2H development board
 
 A small number of new boards for already supported SoCs also debut:
 
  - Allwinner sunxi:
     Only one new machine, revision v1.2 of the Pine64 PinePhone
     (non-Android) smartphone, containing minor changes compared to
     earlier versions.
 
  - Amlogic Meson:
     WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
 
  - Aspeed:
     EthanolX is AMD's EPYC data center rerence platform, using an
     ASpeed AST2600 baseboard management controller.
 
  - Mediatek:
     Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook
     based on the MT8183 (Helio P60t) SoC.
 
  - Nvidia Tegra:
     ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
     tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
     Thanks to PostmarketOS, these can now run mainline kernels
     and become useful again.
 
     The Jetson Xavier NX Developer Kit uses a SoM and carrier board
     for the Tegra194, their latest 64-bit chip based on Carmel CPU
     cores and Volta graphics.
 
  - NXP i.MX:
     Five new boards based on the 32-bit i.MX6 series are added:
     The MYiR MYS-6ULX single-board computer, and four different
     models of industrial computers from Protonic.
 
  - Qualcomm:
     MikroTik RouterBoard 3011 is a rackmounted router based on the
     32-bit IPQ8064 networking SoC
     Three older phones get added, the Snapdragon 808 (msm8992) based
     Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
     Windows Phone, and the Snapdragon 810 (msm8994) based Sony
     Xperia Z5.
 
  - Renesas:
     In addition to the HiHope RZ/G2H board mentioned above, we gain
     support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
     RZ/G2N reference boards.
     Beacon EmbeddedWorks adds another SoM+Carrier development board
     for RZ/G2M.
 
  - Rockchips:
     Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it
     is based on, using the high-end 32-bit rk3288 SoC.
 
 Notable updates to existing platforms are usually for added on-chip
 peripherals, including:
 
  - ASpeed AST2xxx (various)
 
  - Allwinner (cpufreq, thermal, Pinephone touchscreen)
 
  - Amlogic Meson (audio, gpu dvdfs, board updates)
 
  - Arm Versatile
 
  - Broadcom (board updates for switch ports, Raspberry pi clock updates)
 
  - Hisilicon (various)
 
  - Intel/Altera SoCFPGA (various)
 
  - Marvell Armada 7xxx/8xxx (smmu)
 
  - Marvell MMP (GPU on mmp2/mmp3)

Pull ARM SoC DT updates from Arnd Bergmann:
 "As usual, there are many patches addressing minor issues in existing
  DTS files, such as DTC warnings, or adding support for additional
  peripherals.

  There are three added SoCs in existing product families:

   - Amazon:

     Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
     otherwise known as AL73400 or first-generation Graviton, and
     following the already supported Cortex-A1`5 and Cortex-A57 based
     Alpine chips. This one is added together with the official
     Evaluation platform.

   - Qualcomm:

     The Snapdragon SDM630 platform is a family of mid-range mobile
     phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total
     of five end-user products are added based on these, all Android
     phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra.

   - Renesas:

     RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
     family, and apparently closely related to the RZ/G2N and RZ/G2M
     models we already support but has a faster GPU and additional
     on-chip peripherals. It is added along with the HopeRun HiHope
     RZ/G2H development board

  A small number of new boards for already supported SoCs also debut:

   - Allwinner sunxi:

     Only one new machine, revision v1.2 of the Pine64 PinePhone
     (non-Android) smartphone, containing minor changes compared to
     earlier versions.

   - Amlogic Meson:

     WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box

   - Aspeed:

     EthanolX is AMD's EPYC data center rerence platform, using an
     ASpeed AST2600 baseboard management controller.

   - Mediatek:

     Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based
     on the MT8183 (Helio P60t) SoC.

   - Nvidia Tegra:

     ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
     tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
     Thanks to PostmarketOS, these can now run mainline kernels and
     become useful again.

     The Jetson Xavier NX Developer Kit uses a SoM and carrier board for
     the Tegra194, their latest 64-bit chip based on Carmel CPU cores
     and Volta graphics.

   - NXP i.MX:

     Five new boards based on the 32-bit i.MX6 series are added: The
     MYiR MYS-6ULX single-board computer, and four different models of
     industrial computers from Protonic.

   - Qualcomm:

     MikroTik RouterBoard 3011 is a rackmounted router based on the
     32-bit IPQ8064 networking SoC

     Three older phones get added, the Snapdragon 808 (msm8992) based
     Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
     Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia
     Z5.

   - Renesas:

     In addition to the HiHope RZ/G2H board mentioned above, we gain
     support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
     RZ/G2N reference boards. Beacon EmbeddedWorks adds another
     SoM+Carrier development board for RZ/G2M.

   - Rockchips:

     Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is
     based on, using the high-end 32-bit rk3288 SoC.

  Notable updates to existing platforms are usually for added on-chip
  peripherals, including:

   - ASpeed AST2xxx (various)

   - Allwinner (cpufreq, thermal, Pinephone touchscreen)

   - Amlogic Meson (audio, gpu dvdfs, board updates)

   - Arm Versatile

   - Broadcom (board updates for switch ports, Raspberry pi clock updates)

   - Hisilicon (various)

   - Intel/Altera SoCFPGA (various)

   - Marvell Armada 7xxx/8xxx (smmu)

   - Marvell MMP (GPU on mmp2/mmp3)

   - Mediatek mt8183 (USB, pericfg)

   - NXP Layerscape (VPU, thermal, DSPI)

   - NXP i.MX (VPU, bindings, board updates)

   - Nvidia Tegra194 (GPU)

   - Qualcomm (GPU, Interconnect, ...)

   - Renesas R-Car (SPI, IPMMU, board updates)

   - STMicroelectronics STM32 (various)

   - Samsung Exynos (various)

   - Socionext Uniphier (updates to serial, and pcie)

   - TI K3 (serdes, usb3, audio, sd, chipid)

   - TI OMAP (IPU/DSP remoteproc changes, dropping platform data)"

Linus Torvalds e4cbce4d13 The main changes in this cycle were:
- Improve uclamp performance by using a static key for the fast path
 
  - Add the "sched_util_clamp_min_rt_default" sysctl, to optimize for
    better power efficiency of RT tasks on battery powered devices.
    (The default is to maximize performance & reduce RT latencies.)
 
  - Improve utime and stime tracking accuracy, which had a fixed boundary
    of error, which created larger and larger relative errors as the values
    become larger. This is now replaced with more precise arithmetics,
    using the new mul_u64_u64_div_u64() helper in math64.h.
 
  - Improve the deadline scheduler, such as making it capacity aware
 
  - Improve frequency-invariant scheduling
 
  - Misc cleanups in energy/power aware scheduling
 
  - Add sched_update_nr_running tracepoint to track changes to nr_running
 
  - Documentation additions and updates

Linus Torvalds b34133fec8 - HW support updates:
- Add uncore support for Intel Comet Lake
 
    - Add RAPL support for Hygon Fam18h
 
    - Add Intel "IIO stack to PMON mapping" support on Skylake-SP CPUs,
      which enumerates per device performance counters via sysfs and enables
      the perf stat --iiostat functionality
 
    - Add support for Intel "Architectural LBRs", which generalized the model
      specific LBR hardware tracing feature into a model-independent, architected
      performance monitoring feature. Usage is mostly seamless to tooling, as the
      pre-existing LBR features are kept, but there's a couple of advantages
      under the hood, such as faster context-switching, faster LBR reads,
      cleaner exposure of LBR features to guest kernels, etc.
 
      ( Since architectural LBRs are supported via XSAVE, there's related
        changes to the x86 FPU code as well. )
 
  - ftrace/perf updates: Add support to add a text poke event to record changes
                         to kernel text (i.e. self-modifying code) in order to
                         support tracers like Intel PT decoding through

Linus Torvalds 145ff1ec09 arm64 and cross-arch updates for 5.9:
- Removal of the tremendously unpopular read_barrier_depends() barrier,
   which is a NOP on all architectures apart from Alpha, in favour of
   allowing architectures to override READ_ONCE() and do whatever dance
   they need to do to ensure address dependencies provide LOAD ->
   LOAD/STORE ordering. This work also offers a potential solution if
   compilers are shown to convert LOAD -> LOAD address dependencies into
   control dependencies (e.g. under LTO), as weakly ordered architectures
   will effectively be able to upgrade READ_ONCE() to smp_load_acquire().
   The latter case is not used yet, but will be discussed further at LPC.
 
 - Make the MSI/IOMMU input/output ID translation PCI agnostic, augment
   the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
   bus-specific parameter and apply the resulting changes to the device
   ID space provided by the Freescale FSL bus.
 
 - arm64 support for TLBI range operations and translation table level
   hints (part of the ARMv8.4 architecture version).
 
 - Time namespace support for arm64.
 
 - Export the virtual and physical address sizes in vmcoreinfo for
   makedumpfile and crash utilities.
 
 - CPU feature handling cleanups and checks for programmer errors
   (overlapping bit-fields).
 
 - ACPI updates for arm64: disallow AML accesses to EFI code regions and
   kernel memory.
 
 - perf updates for arm64.
 
 - Miscellaneous fixes and cleanups, most notably PLT counting
   optimisation for module loading, recordmcount fix to ignore
   relocations other than R_AARCH64_CALL26, CMA areas reserved for
   gigantic pages on 16K and 64K configurations.
 
 - Trivial typos, duplicate words.

Merge tag 'rm-unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux

Pull unicore32 removal from Mike Rapoport:
 "Remove unicore32 support.

  The unicore32 port do not seem maintained for a long time now, there
  is no upstream toolchain that can create unicore32 binaries and all
  the links to prebuilt toolchains for unicore32 are dead. Even
  compilers that were available are not supported by the kernel anymore.

  Guenter Roeck says:
    "I have stopped building unicore32 images since v4.19 since there is
     no available compiler that is still supported by the kernel. I am
     surprised that support for it has not been removed from the kernel"

  However, it's worth pointing out two things:

   - Guan Xuetao is still listed as maintainer and asked for the port to
     be kept around the last time Arnd suggested removing it two years
     ago. He promised that there would be compiler sources (presumably
     llvm), but has not made those available since.

   - https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
     released in 2016, with patches dated early 2019. These patches
     mainly restore a syscall ABI that was never part of mainline Linux
     but apparently used in production. qemu-2.8 removed support for
     that ABI and newer kernels (4.19+) can no longer be built with the
     old toolchain, so apparently there will not be any future updates
     to that git tree"

Jakub Kicinski 966e505976 udp_tunnel: add the ability to hard-code IANA VXLAN
mlx5 has the IANA VXLAN port (4789) hard coded by the device,
instead of being added dynamically when tunnels are created.

To support this add a workaround flag to struct udp_tunnel_nic_info.
Skipping updates for the port is fairly trivial, dumping the hard
coded port via ethtool requires some code duplication. The port
is not a part of any real table, we dump it in a special table
which has no tunnel types supported and only one entry.

This is the last known workaround / hack needed to convert
all drivers to the new infra.

Linus Torvalds 690b25675f fscrypt updates for 5.9
This release, we add support for inline encryption via the blk-crypto
 framework which was added in 5.8.  Now when an ext4 or f2fs filesystem
 is mounted with '-o inlinecrypt', the contents of encrypted files will
 be encrypted/decrypted via blk-crypto, instead of directly using the
 crypto API.  This model allows taking advantage of the inline encryption
 hardware that is integrated into the UFS or eMMC host controllers on
 most mobile SoCs.  Note that this is just an alternate implementation;
 the ciphertext written to disk stays the same.
 
 (This pull request does *not* include support for direct I/O on
 encrypted files, which blk-crypto makes possible, since that part is
 still being discussed.)
 
 Besides the above feature update, there are also a few fixes and
 cleanups, e.g. strengthening some memory barriers that may be too weak.
 
 All these patches have been in linux-next with no reported issues.  I've
 also tested them with the fscrypt xfstests, as usual.  It's also been
 tested that the inline encryption support works with the support for
 Qualcomm and Mediatek inline encryption hardware that will be in the

Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt

Pull fscrypt updates from Eric Biggers:
 "This release, we add support for inline encryption via the blk-crypto
  framework which was added in 5.8.

  Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
  the contents of encrypted files will be encrypted/decrypted via
  blk-crypto, instead of directly using the crypto API. This model
  allows taking advantage of the inline encryption hardware that is
  integrated into the UFS or eMMC host controllers on most mobile SoCs.

  Note that this is just an alternate implementation; the ciphertext
  written to disk stays the same.

  (This pull request does *not* include support for direct I/O on
  encrypted files, which blk-crypto makes possible, since that part is
  still being discussed.)

  Besides the above feature update, there are also a few fixes and
  cleanups, e.g. strengthening some memory barriers that may be too
  weak.

  All these patches have been in linux-next with no reported issues.
  I've also tested them with the fscrypt xfstests, as usual. It's also
  been tested that the inline encryption support works with the support
  for Qualcomm and Mediatek inline encryption hardware that will be in
  the scsi pull request for 5.9. Also, several SoC vendors are already
  using a previous, functionally equivalent version of these patches"

Takashi Iwai 103f528d3b ASoC: Updates for v5.9
The biggest changes here one again come from Mormioto-san who has
 continued his dilligent work cleaning up long standing issues in the
 APIs, it's particularly nice to see the transition from digital_mute()
 to mute_stream() finally completed. There's also been a lot of work on
 the x86 code again, this time a big focus has been on cleaning up some
 issues identified by various static tests, and on the Freescale systems.
 Otherwise the biggest thing has been a lot of driver additions:
 
  - Convert users of digital_mute() to mute_stream().
  - Simplify I/O helper functions.
  - Add a helper for getting the RTD from a substream.
  - Many, many fixes and cleanups to the x86 code.
  - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
    MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
    Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
    of the first phones I worked on!) and TI J721e EVM.

believe both examples are supposed to be independent of each other.

Let's fix the bindings.

Vaibhav Jain 2d02bf835e powerpc/papr_scm: Fetch nvdimm performance stats from PHYP
Update papr_scm.c to query dimm performance statistics from PHYP via
H_SCM_PERFORMANCE_STATS hcall and export them to user-space as PAPR
specific NVDIMM attribute 'perf_stats' in sysfs. The patch also
provide a sysfs ABI documentation for the stats being reported and
their meanings.

During NVDIMM probe time in papr_scm_nvdimm_init() a special variant
of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of
performance statistics is supported or not. If successful then a PHYP
returns a maximum possible buffer length needed to read all
performance stats. This returned value is stored in a per-nvdimm
attribute 'stat_buffer_len'.

The layout of request buffer for reading NVDIMM performance stats from
PHYP is defined in 'struct papr_scm_perf_stats' and 'struct
papr_scm_perf_stat'. These structs are used in newly introduced
drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall.

The sysfs access function perf_stats_show() uses value
'stat_buffer_len' to allocate a buffer large enough to hold all
possible NVDIMM performance stats and passes it to
drc_pmem_query_stats() to populate. Finally statistics reported in the
buffer are formatted into the sysfs access function output buffer.

Ingo Molnar 28cff52eae Merge branch 'linus' into locking/core, to resolve conflict
Conflicts:

As Stephen Rothwell noted, there's a conflict between this commit
in locking/core:

  a21ee6055c ("lockdep: Change hardirq{s_enabled,_context} to per-cpu variables")

and this fresh upstream commit:

  aa54ea903a ("ARM: percpu.h: fix build error")

a21ee6055c is a simpler solution to the dependency problem and doesn't
further increase header hell - so this conflict resolution effectively
reverts aa54ea903a and uses the a21ee6055c solution.

Nick Terrell fb46d057db x86: Add support for ZSTD compressed kernel
- Add support for zstd compressed kernel

- Define __DISABLE_EXPORTS in Makefile

- Remove __DISABLE_EXPORTS definition from kaslr.c

- Bump the heap size for zstd.

- Update the documentation.

Integrates the ZSTD decompression code to the x86 pre-boot code.

Zstandard requires slightly more memory during the kernel decompression
on x86 (192 KB vs 64 KB), and the memory usage is independent of the
window size.

__DISABLE_EXPORTS is now defined in the Makefile, which covers both
the existing use in kaslr.c, and the use needed by the zstd decompressor
in misc.c.

This patch has been boot tested with both a zstd and gzip compressed
kernel on i386 and x86_64 using buildroot and QEMU.

Additionally, this has been tested in production on x86_64 devices.
We saw a 2 second boot time reduction by switching kernel compression
from xz to zstd.

Chanwoo Choi 4dc3bab868 PM / devfreq: Add support delayed timer for polling mode
Until now, the devfreq driver using polling mode like simple_ondemand
governor have used only deferrable timer for reducing the redundant
power consumption. It reduces the CPU wake-up from idle due to polling mode
which check the status of Non-CPU device.

But, it has a problem for Non-CPU device like DMC device with DMA operation.
Some Non-CPU device need to do monitor continuously regardless of CPU state
in order to decide the proper next status of Non-CPU device.

So, add support the delayed timer for polling mode to support
the repetitive monitoring. The devfreq driver and user can select
the kind of timer on either deferrable and delayed timer.

For example, change the timer type of DMC device
based on Exynos5422-based Odroid-XU3 as following:

- If want to use deferrable timer as following:
echo deferrable > /sys/class/devfreq/10c20000.memory-controller/timer

- If want to use delayed timer as following:
echo delayed > /sys/class/devfreq/10c20000.memory-controller/timer

Ido Schimmel ec4f5b3617 mlxsw: spectrum: Use different trap group for externally routed packets
Cited commit mistakenly removed the trap group for externally routed
packets (e.g., via the management interface) and grouped locally routed
and externally routed packet traps under the same group, thereby
subjecting them to the same policer.

This can result in problems, for example, when FRR is restarted and
suddenly all transient traffic is trapped to the CPU because of a
default route through the management interface. Locally routed packets
required to re-establish a BGP connection will never reach the CPU and
the routing tables will not be re-populated.

Fix this by using a different trap group for externally routed packets.

Ahmed S. Darwish 55f3560df9 seqlock: Extend seqcount API with associated locks
A sequence counter write side critical section must be protected by some
form of locking to serialize writers. If the serialization primitive is
not disabling preemption implicitly, preemption has to be explicitly
disabled before entering the write side critical section.

There is no built-in debugging mechanism to verify that the lock used
for writer serialization is held and preemption is disabled. Some usage
sites like dma-buf have explicit lockdep checks for the writer-side
lock, but this covers only a small portion of the sequence counter usage
in the kernel.

Add new sequence counter types which allows to associate a lock to the
sequence counter at initialization time. The seqcount API functions are
extended to provide appropriate lockdep assertions depending on the
seqcount/lock type.

For sequence counters with associated locks that do not implicitly
disable preemption, preemption protection is enforced in the sequence
counter write side functions. This removes the need to explicitly add
preempt_disable/enable() around the write side critical sections: the
write_begin/end() functions for these new sequence counter types
automatically do this.

Introduce the following seqcount types with associated locks:

     seqcount_spinlock_t
     seqcount_raw_spinlock_t
     seqcount_rwlock_t
     seqcount_mutex_t
     seqcount_ww_mutex_t

Extend the seqcount read and write functions to branch out to the
specific seqcount_LOCKTYPE_t implementation at compile-time. This avoids
kernel API explosion per each new seqcount_LOCKTYPE_t added. Add such
compile-time type detection logic into a new, internal, seqlock header.

Document the proper seqcount_LOCKTYPE_t usage, and rationale, at
Documentation/locking/seqlock.rst.

If lockdep is disabled, this lock association is compiled out and has
neither storage size nor runtime overhead.

Proper documentation for the design and usage of sequence counters and
sequential locks does not exist. Complete the seqlock.h documentation as
follows:

  - Divide all documentation on a seqcount_t vs. seqlock_t basis. The
    description for both mechanisms was intermingled, which is incorrect
    since the usage constrains for each type are vastly different.

  - Add an introductory paragraph describing the internal design of, and
    rationale for, sequence counters.

  - Document seqcount_t writer non-preemptibility requirement, which was
    not previously documented anywhere, and provide a clear rationale.

  - Provide template code for seqcount_t and seqlock_t initialization
    and reader/writer critical sections.

  - Recommend using seqlock_t by default. It implicitly handles the
    serialization and non-preemptibility requirements of writers.

At seqlock.h:

  - Remove references to brlocks as they've long been removed from the
    kernel.

  - Remove references to gcc-3.x since the kernel's minimum supported
    gcc version is 4.9.

Aneesh Kumar K.V bf6b7661f4 powerpc/book3s64/radix: Add kernel command line option to disable radix GTSE
This adds a kernel command line option that can be used to disable GTSE support.
Disabling GTSE implies kernel will make hcalls to invalidate TLB entries.

This was done so that we can do VM migration between configs that enable/disable
GTSE support via hypervisor. To migrate a VM from a system that supports
GTSE to a system that doesn't, we can boot the guest with
radix_hcall_invalidate=on, thereby forcing the guest to use hcalls for TLB
invalidates.

The check for hcall availability is done in pSeries_setup_arch so that
the panic message appears on the console. This should only happen on
a hypervisor that doesn't force the guest to hash translation even
though it can't handle the radix GTSE=0 request via CAS. With
radix_hcall_invalidate=on if the hypervisor doesn't support hcall_rpt_invalidate
hcall it should force the LPAR to hash translation.

activate interface. Register dimm level operations to arm/disarm

platform-quiesce time relative to the number of dimms armed for firmware

A new nfit-specific bus attribute "firmware_activate_noidle" is added to
allow the activation to switch between platform enforced, and OS
opportunistic device quiesce. In other words, let the hibernate cycle
handle in-flight device-dma rather than the platform attempting to
increase PCI-E timeouts and the like.

Dan Williams 48001ea50d PM, libnvdimm: Add runtime firmware activation support
Abstract platform specific mechanics for nvdimm firmware activation
behind a handful of generic ops. At the bus level ->activate_state()
indicates the unified state (idle, busy, armed) of all DIMMs on the bus,
and ->capability() indicates the system state expectations for activate.
At the DIMM level ->activate_state() indicates the per-DIMM state,
->activate_result() indicates the outcome of the last activation
attempt, and ->arm() attempts to transition the DIMM from 'idle' to
'armed'.

A new hibernate_quiet_exec() facility is added to support firmware
activation in an OS defined system quiesce state. It leverages the fact
that the hibernate-freeze state wants to assert that a memory
hibernation snapshot can be taken. This is in contrast to a platform
firmware defined quiesce state that may forcefully quiet the memory
controller independent of whether an individual device-driver properly
supports hibernate-freeze.

The libnvdimm sysfs interface is extended to support detection of a
firmware activate capability. The mechanism supports enumeration and
triggering of firmware activate, optionally in the
hibernate_quiet_exec() context.

Jacob Keller b8265621f4 Add pldmfw library for PLDM firmware update
The pldmfw library is used to implement common logic needed to flash
devices based on firmware files using the format described by the PLDM
for Firmware Update standard.

This library consists of logic to parse the PLDM file format from
a firmware file object, as well as common logic for sending the relevant
PLDM header data to the device firmware.

A simple ops table is provided so that device drivers can implement
device specific hardware interactions while keeping the common logic to
the pldmfw library.

This library will be used by the Intel ice networking driver as part of
implementing device flash update via devlink. The library aims to be
vendor and device agnostic. For this reason, it has been placed in
lib/pldmfw, in the hopes that other devices which use the PLDM firmware
file format may benefit from it in the future. However, do note that not
all features defined in the PLDM standard have been implemented.

Linus Torvalds fb896c9107 ARM: SoC DT fixes for v5.8
These are the latest device tree fixes for Arm SoCs:
 
   - TI Keystone2 ethernet regressed after a driver change broke with
     incorrect phy-mode in a board's DT source.
 
   - A similar fix is needed for two i.MX boards that were missed in
     an earlier bugfix.
 
   - DT change for Armada 38x allowing to add the register needed to fix
     NETA lockup when repeatedly switching speed.
 
   - One fix on imx6qdl-icore pin muxing to get USB OTG_ID and SD card
     detect work correctly.
 
   - Two fixes for the Allwinner SoCs, one to relax the CMA allocation
     ranges that were failing on older SoCs and one to fix Cedrus on the H6.

Ram Pai dfaa973ae9 KVM: PPC: Book3S HV: In H_SVM_INIT_DONE, migrate remaining normal-GFNs to secure-GFNs
The Ultravisor is expected to explicitly call H_SVM_PAGE_IN for all the
pages of the SVM before calling H_SVM_INIT_DONE. This causes a huge
delay in tranistioning the VM to SVM. The Ultravisor is only interested
in the pages that contain the kernel, initrd and other important data
structures. The rest contain throw-away content.

However if not all pages are requested by the Ultravisor, the Hypervisor
continues to consider the GFNs corresponding to the non-requested pages
as normal GFNs. This can lead to data-corruption and undefined behavior.

In H_SVM_INIT_DONE handler, move all the PFNs associated with the SVM's
GFNs to secure-PFNs. Skip the GFNs that are already Paged-in or Shared
or Paged-in followed by a Paged-out.

Page-merging of pages in memory-slots associated with a Secure VM
is disabled in H_SVM_PAGE_IN handler.

This operation should have been done the much earlier; the moment the VM
is initiated for secure-transition. Delaying this operation increases
the probability for those pages to acquire new references, making it
impossible to migrate those pages in H_SVM_PAGE_IN handler.

Disable page-migration in H_SVM_INIT_START handling.

ASoC: dt-bindings: q6asm: Add Q6ASM_DAI_{TX_RX, TX, RX} defines
Right now the direction of a DAI has to be specified as a literal
number in the device tree, e.g.:

	dai@0 {
		reg = <0>;
		direction = <2>;
	};

but this does not make it immediately clear that this is a
playback/RX-only DAI.

Actually, q6asm-dai.c has useful defines for this. Move them to the
dt-bindings header to allow using them in the dts(i) files.
The example above then becomes:

	dai@0 {
		reg = <0>;
		direction = <Q6ASM_DAI_RX>;
	};

which is immediately recognizable as playback/RX-only DAI.

Sumeet Pawnikar 8365a898fe powercap: Add Power Limit4 support
Modern Intel Mobile platforms support power limit4 (PL4), which is
the SoC package level maximum power limit (in Watts). It can be used
to preemptively limits potential SoC power to prevent power spikes
from tripping the power adapter and battery over-current protection.
This patch enables this feature by exposing package level peak power
capping control to userspace via RAPL sysfs interface. With this,
application like DTPF can modify PL4 power limit, the similar way
of other package power limit (PL1).
As this feature is not tested on previous generations, here it is
enabled only for the platform that has been verified to work,
for safety concerns.

David S. Miller a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

Jim Cromie e20e310c81 dyndbg-docs: eschew file /full/path query in docs
Regarding:
commit 2b6783191d ("dynamic_debug: add trim_prefix() to provide source-root relative paths")
commit a73619a845 ("kbuild: use -fmacro-prefix-map to make __FILE__ a relative path")

2nd commit broke dynamic-debug's "file $fullpath" query form, but
nobody noticed because 1st commit had trimmed prefixes from
control-file output, so the click-copy-pasting of fullpaths into new
queries had ceased; that query form became unused.

Removing the function is cleanest, but it could be useful in
old-compiler corner cases, where __FILE__ still has /full/path,
and it safely does nothing otherwize.

So instead, quietly deprecate "file /full/path" query form, by
removing all /full/paths examples in the docs.  I skipped adding a
back-compat note.

Marius Zachmann fa4dac3e1b hwmon: (corsair-cpro) add reading pwm values
This adds the possibility for reading pwm values.
These can not be read if the device is controlled via
fan_target or a fan curve and will return an error in
this case. Since an error is expected, this adds some
rudimentary error handling.

Changes:
- add CTL_GET_FAN_PWM and use it via get_data
- pwm returns -ENODATA if the device returns error 0x12
- fan_target now returns -ENODATA when the driver is
  started or a pwm value is set.
- add ccp_get_errno to determine errno from device error.
- get_data now has a parameter to determine whether
  to read one or two bytes of data.
- update documentation
- fix missing surname in MAINTAINERS

Marius Zachmann 40c3a44542 hwmon: add Corsair Commander Pro driver
This is v7 of a driver for the Corsair Commander Pro.
It provides sysfs attributes for:
- Reading fan speed
- Reading temp sensors
- Reading voltage values
- Writing pwm and reading last written pwm
- Reading fan and temp connection status

It is an usb driver, so it needs to be ignored by usbhid.
The Corsair Commander Pro is a fan controller and provides
no means for user interaction.
The two device numbers are there, because there is a slightly
different version of the same device. (Only difference
seem to be in some presets.)

Squashed:
 hwmon: (corsair-cpro) add fan_target

 This adds fan_target entries to the corsair-cpro driver.
 Reading the attribute from the device does not seem possible, so
 it returns the last set value (same as pwm).

 send_usb_cmd now has one more argument, which is needed for the
 fan_target command.

 hwmon: corsair-cpro: Change to HID driver

 This changes corsair-cpro to a hid driver using hid reports.
