3e414b5bd2 - crypto and DM crypt advances that allow the crypto API to reclaim 
implementation details that do not belong in DM crypt.  The wrapper
   template for ESSIV generation that was factored out will also be used
   by fscrypt in the future.
 
 - Add root hash pkcs#7 signature verification to the DM verity target.
 
 - Add a new "clone" DM target that allows for efficient remote
   replication of a device.
 
 - Enhance DM bufio's cache to be tailored to each client based on use.
   Clients that make heavy use of the cache get more of it, and those
   that use less have reduced cache usage.
 
 - Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the
   version number of a DM target (even if the associated module isn't yet
   loaded).
 
 - Fix invalid memory access in DM zoned target.
 
 - Fix the max_discard_sectors limit advertised by the DM raid target; it
   was mistakenly storing the limit in bytes rather than sectors.
 
 - Small optimizations and cleanups in DM writecache target.
 
 - Various fixes and cleanups in DM core, DM raid1 and space map portion
   of DM persistent data library.

84da111de0 hmm related patches for 5.4 
This is more cleanup and consolidation of the hmm APIs and the very
 strongly related mmu_notifier interfaces. Many places across the tree
 using these interfaces are touched in the process. Beyond that a cleanup
 to the page walker API and a few memremap related changes round out the
 series:
 
 - General improvement of hmm_range_fault() and related APIs, more
   documentation, bug fixes from testing, API simplification &
   consolidation, and unused API removal
 
 - Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
   make them internal kconfig selects
 
 - Hoist a lot of code related to mmu notifier attachment out of drivers by
   using a refcount get/put attachment idiom and remove the convoluted
   mmu_notifier_unregister_no_release() and related APIs.
 
 - General API improvement for the migrate_vma API and revision of its only
   user in nouveau
 
 - Annotate mmu_notifiers with lockdep and sleeping region debugging
 
 Two series unrelated to HMM or mmu_notifiers came along due to
 dependencies:
 
 - Allow pagemap's memremap_pages family of APIs to work without providing
   a struct device
 
 - Make walk_page_range() and related use a constant structure for function
   pointers

f97c81dc6c ARM: SoC: late updates for v5.4 
This is some material that we picked up into our tree late or
 that had complex inter-depondencies. The fact that there are these
 interdependencies tends to meant that these are often actually the most
 interesting new additions:
 
 The new Aspeed AST2600 baseboard management controller is added, this
 is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
 dependencies on other device drivers.
 
 After many years, support for the MMP2 based OLPC XO-1.75 finally makes
 it into the kernel.
 
 The Armada 3720 based Turris Mox open source router platform is a late
 addition and it follows some preparatory work across multiple branches.
 
 The OMAP2+ platform had some large-scale cleanup involving driver
 changes and DT changes, here we finish it off, dropping a lot of the
 now-unused platform data.
 
 The TI K3 platform that got added for 5.3 gains a lot more support
 for individual bits on the SoC, this part just came late for the
 merge window.

a703d279c5 We have a small collection of core framework updates this time, mostly around 
clk registration by clk providers and debugfs "nice to haves" for rate
 constraints. I'll highlight that we're now setting the clk_init_data pointer
 inside struct clk_hw to NULL during clk_register(), which may break some
 drivers that thought they could use that pointer during normal operations. That
 change has been sitting in next for a while now but maybe something is still
 broken. We'l see. Other than that the core framework changes aren't invasive
 and they're fixing bugs, simplifying, and making things better.
 
 On the clk driver side we got the usual addition of new SoC support, new
 features for existing drivers, and bug fixes scattered throughout. The biggest
 diffstat is the Amlogic driver that gained CPU clk support in addition to
 migrating to the new way of specifying clk parents. After that the Qualcomm,
 i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
 clock controllers from those vendors.
 
 Core:
  - Drop NULL checks in clk debugfs
  - Add min/max rates to clk debugfs
  - Set clk_init_data pointer inside clk_hw to NULL after registration
  - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
  - Evict parents from parent cache when they're unregistered
 
 New Drivers:
  - Add clock driver for i.MX8MN SoCs
  - Support aspeed AST2600 SoCs
  - Support for Mediatek MT6779 SoCs
  - Support qcom SM8150 GCC and RPMh clks
  - Support qcom QCS404 WCSS clks
  - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
  - Addition of clock driver for Rockchip rk3308 SoCs
 
 Updates:
  - Add regulator support to the cdce925 clk driver
  - Add support for Raspberry Pi 4 bcm2711 SoCs
  - Add SDIO gate support to aspeed driver
  - Add missing of_node_put() calls in various clk drivers
  - Migrate Amlogic driver to new clock parent description method
  - Add DVFS support to Amlogic Meson g12
  - Add Amlogic Meson g12a reset support to the axg audio clock controller
  - Add sm1 support to the Amlogic Meson g12a clock controller
  - Switch i.MX8MM clock driver to platform driver
  - Add Hifi4 DSP related clocks for i.MX8QXP SoC
  - Fix Audio PLL setting and parent clock for USB
  - Misc i.MX8 clock driver improvements and corrections
  - Set floor ops for Qualcomm SD clks so that rounding works
  - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
  - Enable the Allwinner V3 SoC and fix the i2s clock for H6

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "We have a small collection of core framework updates this time, mostly
  around clk registration by clk providers and debugfs "nice to haves"
  for rate constraints. I'll highlight that we're now setting the
  clk_init_data pointer inside struct clk_hw to NULL during
  clk_register(), which may break some drivers that thought they could
  use that pointer during normal operations. That change has been
  sitting in next for a while now but maybe something is still broken.
  We'l see. Other than that the core framework changes aren't invasive
  and they're fixing bugs, simplifying, and making things better.

  On the clk driver side we got the usual addition of new SoC support,
  new features for existing drivers, and bug fixes scattered throughout.
  The biggest diffstat is the Amlogic driver that gained CPU clk support
  in addition to migrating to the new way of specifying clk parents.
  After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
  support for various new SoCs and clock controllers from those vendors.

  Core:
   - Drop NULL checks in clk debugfs
   - Add min/max rates to clk debugfs
   - Set clk_init_data pointer inside clk_hw to NULL after registration
   - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
   - Evict parents from parent cache when they're unregistered

  New Drivers:
   - Add clock driver for i.MX8MN SoCs
   - Support aspeed AST2600 SoCs
   - Support for Mediatek MT6779 SoCs
   - Support qcom SM8150 GCC and RPMh clks
   - Support qcom QCS404 WCSS clks
   - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
   - Addition of clock driver for Rockchip rk3308 SoCs

  Updates:
   - Add regulator support to the cdce925 clk driver
   - Add support for Raspberry Pi 4 bcm2711 SoCs
   - Add SDIO gate support to aspeed driver
   - Add missing of_node_put() calls in various clk drivers
   - Migrate Amlogic driver to new clock parent description method
   - Add DVFS support to Amlogic Meson g12
   - Add Amlogic Meson g12a reset support to the axg audio clock controller
   - Add sm1 support to the Amlogic Meson g12a clock controller
   - Switch i.MX8MM clock driver to platform driver
   - Add Hifi4 DSP related clocks for i.MX8QXP SoC
   - Fix Audio PLL setting and parent clock for USB
   - Misc i.MX8 clock driver improvements and corrections
   - Set floor ops for Qualcomm SD clks so that rounding works
   - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
   - Enable the Allwinner V3 SoC and fix the i2s clock for H6"

  - Support for building the kernel to run as a "Secure Virtual Machine", ie. as
    a guest capable of running on a system with an Ultravisor.
 
  - Some changes to our DMA code on bare metal, to allow devices with medium
    sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space.
 
  - Support for firmware assisted crash dumps on bare metal (powernv).
 
  - Two series fixing bugs in and refactoring our PCI EEH code.
 
  - A large series refactoring our exception entry code to use gas macros, both
    to make it more readable and also enable some future optimisations.
 
 As well as many cleanups and other minor features & fixups.

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  It's also pretty large in commit count and new amd header file size.
  The largest thing is four new amdgpu products (navi12/14, arcturus and
  renoir APU support).

  Otherwise it's pretty much lots of work across the board, i915 has
  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework
  (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
  put into the places they are needed.

  uapi:
   - content protection type property for HDCP

  core:
   - rework include dependencies
   - lots of drmP.h removals
   - link rate calculation robustness fix
   - make fb helper map only when required
   - add connector->DDC adapter link
   - DRM_WAIT_ON removed
   - drop DRM_AUTH usage from drivers

Pull input updates from Dmitry Torokhov:

 - input core allows hardware drivers to specify a [more precise]
   timestamp (normally taken in top half) to better track velocity of
   contacts

 - input_dev instances now support "polling" mode so that drivers could
   use the same object for polled and interrupt-driven operation. The
   plan is to convert existing drivers and retire input_polled_dev API

 - a new driver for the FlySky FS-iA6B RC receiver

 - a refresh of BU21013 touchpad driver

 - w90x900 keyboard and touchpad drivers are removed as the platform is
   gone

f60c55a94e fs-verity for 5.4 
Please consider pulling fs-verity for 5.4.
 
 fs-verity is a filesystem feature that provides Merkle tree based
 hashing (similar to dm-verity) for individual readonly files, mainly for
 the purpose of efficient authenticity verification.
 
 This pull request includes:
 
 (a) The fs/verity/ support layer and documentation.
 
 (b) fs-verity support for ext4 and f2fs.
 
 Compared to the original fs-verity patchset from last year, the UAPI to
 enable fs-verity on a file has been greatly simplified.  Lots of other
 things were cleaned up too.
 
 fs-verity is planned to be used by two different projects on Android;
 most of the userspace code is in place already.  Another userspace tool
 ("fsverity-utils"), and xfstests, are also available.  e2fsprogs and
 f2fs-tools already have fs-verity support.  Other people have shown
 interest in using fs-verity too.
 
 I've tested this on ext4 and f2fs with xfstests, both the existing tests
 and the new fs-verity tests.  This has also been in linux-next since
 July 30 with no reported issues except a couple minor ones I found
 myself and folded in fixes for.
 
 Ted and I will be co-maintaining fs-verity.

734d1ed83e fscrypt update for 5.4 
This is a large update to fs/crypto/ which includes:
 
 - Add ioctls that add/remove encryption keys to/from a filesystem-level
   keyring.  These fix user-reported issues where e.g. an encrypted home
   directory can break NetworkManager, sshd, Docker, etc. because they
   don't get access to the needed keyring.  These ioctls also provide a
   way to lock encrypted directories that doesn't use the vm.drop_caches
   sysctl, so is faster, more reliable, and doesn't always need root.
 
 - Add a new encryption policy version ("v2") which switches to a more
   standard, secure, and flexible key derivation function, and starts
   verifying that the correct key was supplied before using it.  The key
   derivation improvement is needed for its own sake as well as for
   ongoing feature work for which the current way is too inflexible.
 
 Work is in progress to update both Android and the 'fscrypt' userspace
 tool to use both these features.  (Working patches are available and
 just need to be reviewed+merged.)  Chrome OS will likely use them too.
 
 This has also been tested on ext4, f2fs, and ubifs with xfstests -- both
 the existing encryption tests, and the new tests for this.  This has
 also been in linux-next since Aug 16 with no reported issues.  I'm also
 using an fscrypt v2-encrypted home directory on my personal desktop.

6cfae0c26b Char/Misc driver patches for 5.4-rc1 
Here is the big char/misc driver pull request for 5.4-rc1.
 
 As has been happening in previous releases, more and more individual
 driver subsystem trees are ending up in here.  Now if that is good or
 bad I can't tell, but hopefully it makes your life easier as it's more
 of an aggregation of trees together to one merge point for you.
 
 Anyway, lots of stuff in here:
 	- habanalabs driver updates
 	- thunderbolt driver updates
 	- misc driver updates
 	- coresight and intel_th hwtracing driver updates
 	- fpga driver updates
 	- extcon driver updates
 	- some dma driver updates
 	- char driver updates
 	- android binder driver updates
 	- nvmem driver updates
 	- phy driver updates
 	- parport driver fixes
 	- pcmcia driver fix
 	- uio driver updates
 	- w1 driver updates
 	- configfs fixes
 	- other assorted driver updates
 
 All of these have been in linux-next for a long time with no reported
 issues.

e6874fc294 Staging/IIO driver patches for 5.4-rc1 
Here is the big staging/iio driver update for 5.4-rc1.
 
 Lots of churn here, with a few driver/filesystems moving out of staging
 finally:
 	- erofs moved out of staging
 	- greybus core code moved out of staging
 
 Along with that, a new filesytem has been added:
 	- extfat
 to provide support for those devices requiring that filesystem (i.e.
 transfer devices to/from windows systems or printers.)
 
 Other than that, there a number of new IIO drivers, and lots and lots
 and lots of staging driver cleanups and minor fixes as people continue
 to dig into those for easy changes.
 
 All of these have been in linux-next for a while with no reported

c6b48dad92 USB changes for 5.4-rc1 
Here is the big set of USB patches for 5.4-rc1.
 
 Two major chunks of code are moving out of the tree and into the staging
 directory, uwb and wusb (wireless USB support), because there are no
 devices that actually use this protocol anymore, and what we have today
 probably doesn't work at all given that the maintainers left many many
 years ago.  So move it to staging where it will be removed in a few
 releases if no one screams.
 
 Other than that, lots of little things.  The usual gadget and xhci and
 usb serial driver updates, along with a bunch of sysfs file cleanups due
 to the driver core changes to support that.  Nothing really major, just
 constant forward progress.

1f7d290a72 Driver core patches for 5.4-rc1 
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:
        - fix a typo in the name of a constant

   - leds-lp5562:
        - allow firmware files up to the maximum length

   - leds-an30259a:
        - fix typo

   - leds-pca953x:
        - include the right header"

6ab8ad3160 sound updates for 5.4 
As shown in diffstat and logs, it was again a busy development
 cycle at this time, too.  The most significant changes are still
 on-going refactoring / modernization works for ASoC core and
 drivers, but there are lots of other changes as well.  Here we go,
 some highlights below:
 
 ASoC:
 - Quite lots of cleanup / refactoring of ASoC core and APIs;
   most of them are systematic, but also including cleanups and
   modernization
 
 - A bulk of updates for some ASoC platforms, Freescale, sunxi and
   Intel SST/SOF
 
 - Initial support for Sound Open Firmware on i.MX8
 
 - Removal of deprecated w90x900 and nuc900 drivers
 
 - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
   7ULP and 8MQ, Meson G12A and NXP UDA1334
 
 USB-audio:
 - More validations of descriptor units for hardening against bugs
   reported by fuzzers
 
 - PCM device assignment workaround for a past call-order change
 
 - Scarlett Gen2 mixer interface, a few more more quirks
 
 HD-audio:
 - Support for audio component with AMD/ATI and Nvidia HDMI codecs
 
 - Clean up HD-audio core and remove indirect access ops for Intel SOF
 
 - DMIC detection at probe; it would make systems automatically falling
   back to SST/SOF driver on devices that need DMIC handling.
   Needs a new Kconfig to set, and beware that it's still new and a bit
   experimental
 
 FireWire:
 - Lots of code refactoring and cleanups

7c672abc12 It's a somewhat calmer cycle for docs this time, as the churn of the mass 
RST conversion is happily mostly behind us.
 
  - A new document on reproducible builds.
 
  - We finally got around to zapping the documentation for hardware support
    that was removed in 2004; one doesn't want to rush these things.
 
  - The usual assortment of fixes, typo corrections, etc.
 
 You'll still find a handful of annoying conflicts against other trees,
 mostly tied to the last RST conversions; resolutions are straightforward
 and the linux-next ones are good.

7f2444d38f Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull core timer updates from Thomas Gleixner:
 "Timers and timekeeping updates:

   - A large overhaul of the posix CPU timer code which is a preparation
     for moving the CPU timer expiry out into task work so it can be
     properly accounted on the task/process.

     An update to the bogus permission checks will come later during the
     merge window as feedback was not complete before heading of for
     travel.

   - Switch the timerqueue code to use cached rbtrees and get rid of the
     homebrewn caching of the leftmost node.

   - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
     single function

   - Implement the separation of hrtimers to be forced to expire in hard
     interrupt context even when PREEMPT_RT is enabled and mark the
     affected timers accordingly.

   - Implement a mechanism for hrtimers and the timer wheel to protect
     RT against priority inversion and live lock issues when a (hr)timer
     which should be canceled is currently executing the callback.
     Instead of infinitely spinning, the task which tries to cancel the
     timer blocks on a per cpu base expiry lock which is held and
     released by the (hr)timer expiry code.

   - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
     resulting in faster access to timekeeping functions.

   - Updates to various clocksource/clockevent drivers and their device
     tree bindings.

   - The usual small improvements all over the place"

a572ba6329 Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull core irq updates from Thomas Gleixner:
 "Updates from the irq departement:

   - Update the interrupt spreading code so it handles numa node with
     different CPU counts properly.

   - A large overhaul of the ARM GiCv3 driver to support new PPI and SPI
     ranges.

   - Conversion of all alloc_fwnode() users to use physical addresses
     instead of virtual addresses so the virtual addresses are not
     leaked. The physical address is sufficient to identify the
     associated interrupt chip.

   - Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips.

   - Enforce interrupt threading at compile time if RT is enabled.

   - Small updates and improvements all over the place"
