Linus Torvalds 8653b778e4 The core framework got some nice improvements this time around. We gained the 
ability to get struct clk pointers from a struct clk_hw so that clk providers
 can consume the clks they provide, if they need to do something like that. This
 has been a long missing part of the clk provider API that will help us move
 away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are
 added for the clk_set_rate() "range" functions, similar to the tracepoints we
 already have for clk_set_rate() and we added a column to debugfs to help
 developers understand the hardware enable state of clks in case firmware or
 bootloader state is different than what is expected. Overall the core changes
 are mostly improving the clk driver writing experience.
 
 At the driver level, we have the usual collection of driver updates and new
 drivers for new SoCs. This time around the Qualcomm folks introduced a good
 handful of clk drivers for various parts of three or four SoCs. The SiFive
 folks added a new clk driver for their FU740 SoCs, coming in second on the
 diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that
 for various new features. One last thing to note in the driver area is that the
 i.MX driver has gained a new binding to support SCU clks after being on the
 list for many months. It uses a two cell binding which is sort of rare in clk
 DT bindings. Beyond that we have the usual set of driver fixes and tweaks that
 come from more testing and finding out that some configuration was wrong or
 that a driver could support being built as a module.
 
 Core:
  - Add some trace points for clk_set_rate() "range" functions
  - Add hardware enable information to clk_summary debugfs
  - Replace clk-provider.h with of_clk.h when possible
  - Add devm variant of clk_notifier_register()
  - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
 
 New Drivers:
  - Bindings for Canaan K210 SoC clks
  - Support for SiFive FU740 PRCI
  - Camera clks on Qualcomm SC7180 SoCs
  - GCC and RPMh clks on Qualcomm SDX55 SoCs
  - RPMh clks on Qualcomm SM8350 SoCs
  - LPASS clks on Qualcomm SM8250 SoCs
 
 Updates:
  - DVFS support for AT91 clk driver
  - Update git repo branch for Renesas clock drivers
  - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
  - Stop using __raw_*() I/O accessors in Renesas clk drivers
  - One more conversion of DT bindings to json-schema
  - Make i.MX clk-gate2 driver more flexible
  - New two cell binding for i.MX SCU clks
  - Drop of_match_ptr() in i.MX8 clk drivers
  - Add arch dependencies for Rockchip clk drivers
  - Fix i2s on Rockchip rk3066
  - Add MIPI DSI clks on Amlogic axg and g12 SoCs
  - Support modular builds of Amlogic clk drivers
  - Fix an Amlogic Video PLL clock dependency
  - Samsung Kconfig dependencies updates for better compile test coverage
  - Refactoring of the Samsung PLL clocks driver
  - Small Tegra driver cleanups
  - Minor fixes to Ingenic and VC5 clk drivers
  - Cleanup patches to remove unused variables and plug memory leaks

Linus Torvalds a409ed156a This is the bulk of the GPIO changes for the v5.11 kernel cycle: 
Core changes:
 
 - Retired the old set-up function for GPIO IRQ chips. All chips
   now use the template struct gpio_irq_chip and pass that to the core
   to be set up alongside the gpio_chip. We can finally get rid of
   the old cruft.
 
 - Some refactoring and clean up of the core code.
 
 - Support edge event timestamps to be stamped using REALTIME
   (wall clock) timestamps. We have found solid use cases for
   this, so we support it.
 
 New drivers:
 
 - MStar MSC313 GPIO driver.
 
 - HiSilicon GPIO driver.
 
 Driver improvements:
 
 - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
 
 - The mockup driver can now be probed from the device tree which
   is pretty useful for virtual prototyping of devices.
 
 - The Rcar driver now supports .get_multiple()
 
 - The MXC driver dropped some legacy and became a pure device
   tree client.
 
 - The Exar driver was moved over to the IDA interface for
   enumerating, and also switched over to using regmap for
   register access.

Linus Torvalds 09c0796adf Tracing updates for 5.11 
The major update to this release is that there's a new arch config option called:
 CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it.
 All the ftrace callbacks now take a struct ftrace_regs instead of a struct
 pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then
 the ftrace_regs will have enough information to read the arguments of the
 function being traced, as well as access to the stack pointer. This way, if
 a user (like live kernel patching) only cares about the arguments, then it
 can avoid using the heavier weight "regs" callback, that puts in enough
 information in the struct ftrace_regs to simulate a breakpoint exception
 (needed for kprobes).
 
 New config option that audits the timestamps of the ftrace ring buffer at
 most every event recorded.  The "check_buffer()" calls will conflict with
 mainline, because I purposely added the check without including the fix that
 it caught, which is in mainline. Running a kernel built from the commit of
 the added check will trigger it.
 
 Ftrace recursion protection has been cleaned up to move the protection to
 the callback itself (this saves on an extra function call for those
 callbacks).
 
 Perf now handles its own RCU protection and does not depend on ftrace to do
 it for it (saving on that extra function call).
 
 New debug option to add "recursed_functions" file to tracefs that lists all
 the places that triggered the recursion protection of the function tracer.
 This will show where things need to be fixed as recursion slows down the
 function tracer.
 
 The eval enum mapping updates done at boot up are now offloaded to a work
 queue, as it caused a noticeable pause on slow embedded boards.
 
 Various clean ups and last minute fixes.

Linus Torvalds ff49c86f27 f2fs-for-5.11-rc1 
In this round, we've made more work into per-file compression support. For
 example, F2FS_IOC_GET|SET_COMPRESS_OPTION provides a way to change the
 algorithm or cluster size per file. F2FS_IOC_COMPRESS|DECOMPRESS_FILE provides
 a way to compress and decompress the existing normal files manually along with
 a new mount option, compress_mode=fs|user, which can control who compresses the
 data. Chao also added a checksum feature with a mount option so that we are able
 to detect any corrupted cluster. In addition, Daniel contributed casefolding
 with encryption patch, which will be used for Android devices.
 
 Enhancement:
  - add ioctls and mount option to manage per-file compression feature
  - support casefolding with encryption
  - support checksum for compressed cluster
  - avoid IO starvation by replacing mutex with rwsem
  - add sysfs, max_io_bytes, to control max bio size
 
 Bug fix:
  - fix use-after-free issue when compression and fsverity are enabled
  - fix consistency corruption during fault injection test
  - fix data offset for lseek
  - get rid of buffer_head which has 32bits limit in fiemap
  - fix some bugs in multi-partitions support
  - fix nat entry count calculation in shrinker
  - fix some stat information
 
 And, we've refactored some logics and fix minor bugs as well.

  For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
  change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
  DECOMPRESS_FILE provides a way to compress and decompress the existing
  normal files manually.

  There is also a new mount option, compress_mode=fs|user, which can
  control who compresses the data.

  Chao also added a checksum feature with a mount option so that
  we are able to detect any corrupted cluster.

  In addition, Daniel contributed casefolding with encryption patch,
  which will be used for Android devices.

  Summary:

  Enhancements:
   - add ioctls and mount option to manage per-file compression feature
   - support casefolding with encryption
   - support checksum for compressed cluster
   - avoid IO starvation by replacing mutex with rwsem
   - add sysfs, max_io_bytes, to control max bio size

  Bug fixes:
   - fix use-after-free issue when compression and fsverity are enabled
   - fix consistency corruption during fault injection test
   - fix data offset for lseek
   - get rid of buffer_head which has 32bits limit in fiemap
   - fix some bugs in multi-partitions support
   - fix nat entry count calculation in shrinker
   - fix some stat information

  And, we've refactored some logics and fix minor bugs as well"

Linus Torvalds 48c1c40ab4 ARM: SoC drivers for v5.11 
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

Linus Torvalds 9805529ec5 ARM: device tree updates for 5.11 
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.
 Interestingly there are more 32-bit machines added this time than
 64-bit. Here is a brief list of the new boards:
 
  - Three new Mikrotik router variants based on Marvell Prestera
    98DX3236, a close relative of the more common Armada XP
 
  - A reference board for the Marvell Armada 382
 
  - Three new servers using ASpeed baseboard management controllers,
    the actual machines being from Bytedance, Facebook and IBM,
    and one machine using the Nuvoton NPCM750 BMC.
 
  - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
 
  - The usual set of 32-bit i.MX industrial/embedded hardware:
    * Protonic WD3 (tractor e-cockpit)
    * Kamstrup OMNIA Flex Concentrator (smart grid platform)
    * Van der Laan LANMCU (food storage)
    * Altesco I6P (vehicle inspection stations)
    * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
 
  - DH electronics STM32MP157C DHCOM, a PicoITX carrier board
    for the aleady supported DHCOM module
 
  - Three new Allwinner SoC based single-board computers:
    * NanoPi R1 (H3 based)
    * FriendlyArm ZeroPi (H3 based)
    * Elimo Initium SBC (S3 based)
 
  - Ouya Game Console based on Nvidia Tegra 3
 
  - Version 5 of the already supported Zynq Z-Turn MYIR Board
 
  - LX2162AQDS, a reference platform for NXP Layerscape
    LX2162A, which is a repackaged 16-core LX2160A
 
  - A series of Kontron i.MX8M Mini baseboard/SoM versions
 
  - Espressobin Ultra, a new variant of the popular Armada 3700 based board,
 
  - IEI Puzzle-M801, a rackmount network appliance based on
    Marvell Armada 8040
 
  - Microsoft Lumia 950 XL, a phone
 
  - HDK855 and HDK865 Hardware development kits for Qualcomm
    sm8250 and sm8150, respectively
 
  - Three new board variants of the "Trogdor" Chromebook
    (sc7180)
 
  - New board variants of the Renesas based "Kingfisher" and
    "HiHope" reference boards
 
  - Kobol Helios64, an open source NAS appliance based on Rockchips
    RK3399
 
  - Engicam PX30.Core, a SoM based on Rockchip PX30, along with
    a few carrier boards.
 
 There is one conflict in mt6577_auxadc.txt, which got replaced in
 another tree and modified here, the modification is already part of
 the new file.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

Linus Torvalds 7a932e5702 asm-generic: cross-architecture timer cleanup 
This cleans up two ancient timer features that were never completed in
 the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
 
 There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
 of clocksource implementations, the ARM EBSA110 platform. Rather than
 changing to use modern timekeeping, we remove the platform entirely as
 Russell no longer uses his machine and nobody else seems to have one
 any more.
 
 The conditional code for using arch_gettimeoffset() is removed as
 a result.
 
 For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
 not using clockevent drivers: parisc, ia64, most of m68k, and one
 Arm platform. These all do timer ticks slighly differently, and this
 gets cleaned up to the point they at least all call the same helper
 function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
 in Kconfig, the polarity is now reversed, with the few remaining ones
 selecting LEGACY_TIMER_TICK instead.

Pull asm-generic cross-architecture timer cleanup from Arnd Bergmann:
 "This cleans up two ancient timer features that were never completed in
  the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.

  There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
  of clocksource implementations, the ARM EBSA110 platform. Rather than
  changing to use modern timekeeping, we remove the platform entirely as
  Russell no longer uses his machine and nobody else seems to have one
  any more.

  The conditional code for using arch_gettimeoffset() is removed as a
  result.

  For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
  not using clockevent drivers: parisc, ia64, most of m68k, and one Arm
  platform. These all do timer ticks slighly differently, and this gets
  cleaned up to the point they at least all call the same helper
  function.

  Instead of most platforms using 'select GENERIC_CLOCKEVENTS' in
  Kconfig, the polarity is now reversed, with the few remaining ones
  selecting LEGACY_TIMER_TICK instead"

Linus Torvalds 2dda5700ef regulator: Updates for v5.11 
This has been a quiet release for the regulator API, a few new drivers
 and the usual fixes and cleanup traffic but not much else going on:
 
  - Optimisations for the handling of voltage enumeration, especially
    with sparse selector sets, from Claudiu Beznea.
  - Support for several ARM SCMI regulators, Dialog DA9121, NXP PF8x00,
    Qualcomm PMX55, PM8350 and PM8350c
 
 The addition of the SCMI regulator driver (which controls regulators via
 system firmware) means that we've pulled in the support for the underlying
 firmware operations from the firmware tree.

   - so many coding style cleanups
   - new IIO drivers
   - Android ION code is finally removed from the tree
   - wimax drivers are moved to staging on their way out of the kernel
 
 Nothing really exciting, just the constant grind of kernel development :)

Linus Torvalds d635a69dd4 Networking updates for 5.11 
Core:
 
  - support "prefer busy polling" NAPI operation mode, where we defer softirq
    for some time expecting applications to periodically busy poll
 
  - AF_XDP: improve efficiency by more batching and hindering
            the adjacency cache prefetcher
 
  - af_packet: make packet_fanout.arr size configurable up to 64K
 
  - tcp: optimize TCP zero copy receive in presence of partial or unaligned
         reads making zero copy a performance win for much smaller messages
 
  - XDP: add bulk APIs for returning / freeing frames
 
  - sched: support fragmenting IP packets as they come out of conntrack
 
  - net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs
 
 BPF:
 
  - BPF switch from crude rlimit-based to memcg-based memory accounting
 
  - BPF type format information for kernel modules and related tracing
    enhancements
 
  - BPF implement task local storage for BPF LSM
 
  - allow the FENTRY/FEXIT/RAW_TP tracing programs to use bpf_sk_storage
 
 Protocols:
 
  - mptcp: improve multiple xmit streams support, memory accounting and
           many smaller improvements
 
  - TLS: support CHACHA20-POLY1305 cipher
 
  - seg6: add support for SRv6 End.DT4/DT6 behavior
 
  - sctp: Implement RFC 6951: UDP Encapsulation of SCTP
 
  - ppp_generic: add ability to bridge channels directly
 
  - bridge: Connectivity Fault Management (CFM) support as is defined in
            IEEE 802.1Q section 12.14.
 
 Drivers:

Linus Torvalds 1ac0884d54 A set of updates for entry/exit handling: 
- More generalization of entry/exit functionality
 
  - The consolidation work to reclaim TIF flags on x86 and also for non-x86
    specific TIF flags which are solely relevant for syscall related work
    and have been moved into their own storage space. The x86 specific part
    had to be merged in to avoid a major conflict.
 
  - The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
    delivery mode of task work and results in an impressive performance
    improvement for io_uring. The non-x86 consolidation of this is going to
    come seperate via Jens.
 
  - The selective syscall redirection facility which provides a clean and
    efficient way to support the non-Linux syscalls of WINE by catching them
    at syscall entry and redirecting them to the user space emulation. This
    can be utilized for other purposes as well and has been designed
    carefully to avoid overhead for the regular fastpath. This includes the
    core changes and the x86 support code.
 
  - Simplification of the context tracking entry/exit handling for the users
    of the generic entry code which guarantee the proper ordering and
    protection.
 
  - Preparatory changes to make the generic entry code accomodate S390
    specific requirements which are mostly related to their syscall restart
    mechanism.

  - A mechanism from Mauro to automatically format Documentation/features
    for the built docs
  - Automatic cross references without explicit :ref: markup
  - A new reset-controller document
  - An extensive new document on reporting problems from Thorsten
 
 That last patch also adds the CC-BY-4.0 license to LICENSES/dual; there was

Linus Torvalds 9c70f04678 The main part of this branch is the ongoing fight against windmills in 
an attempt to have userspace tools not poke at naked MSRs. This round
 deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
 by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
 interface which we already have.
 
 In addition, the msr.ko write filtering's error message points to a new
 summary page which contains the info we collected from helpful reporters
 about which userspace tools write MSRs:
 
   https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about
 
 along with the current status of their conversion.
 
 Rest is the usual small fixes and improvements.

Linus Torvalds 5583ff677b "Intel SGX is new hardware functionality that can be used by 
applications to populate protected regions of user code and data called
 enclaves. Once activated, the new hardware protects enclave code and
 data from outside access and modification.
 
 Enclaves provide a place to store secrets and process data with those
 secrets. SGX has been used, for example, to decrypt video without
 exposing the decryption keys to nosy debuggers that might be used to
 subvert DRM. Software has generally been rewritten specifically to
 run in enclaves, but there are also projects that try to run limited
 unmodified software in enclaves."
 
 Most of the functionality is concentrated into arch/x86/kernel/cpu/sgx/
 except the addition of a new mprotect() hook to control enclave page
 permissions and support for vDSO exceptions fixup which will is used by
 SGX enclaves.
