26a8ea8092 mm/hugetlb: fix memfd_pin_folios resv_huge_pages leak
memfd_pin_folios followed by unpin_folios leaves resv_huge_pages elevated
if the pages were not already faulted in.  During a normal page fault,
resv_huge_pages is consumed here:

hugetlb_fault()
  alloc_hugetlb_folio()
    dequeue_hugetlb_folio_vma()
      dequeue_hugetlb_folio_nodemask()
        dequeue_hugetlb_folio_node_exact()
          free_huge_pages--
      resv_huge_pages--

During memfd_pin_folios, the page is created by calling
alloc_hugetlb_folio_nodemask instead of alloc_hugetlb_folio, and
resv_huge_pages is not modified:

memfd_alloc_folio()
  alloc_hugetlb_folio_nodemask()
    dequeue_hugetlb_folio_nodemask()
      dequeue_hugetlb_folio_node_exact()
        free_huge_pages--

alloc_hugetlb_folio_nodemask has other callers that must not modify
resv_huge_pages.  Therefore, to fix, define an alternate version of
alloc_hugetlb_folio_nodemask for this call site that adjusts
resv_huge_pages.

9ab27b0186 The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
 more excited about the support for loading DT overlays from KUnit tests so that
 we can test how the clk framework parses DT nodes during clk registration. The
 clk framework has some places that are highly DeviceTree dependent so this
 charts the path to extend the KUnit tests to cover even more framework code in
 the future. I've got some more tests on the list that use the DT overlay
 support, but they uncovered issues with clk unregistration that I'm still
 working on fixing.
 
 Outside the core, the clk driver update pile is dominated by Qualcomm and
 Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
 things all over the place, like adding missing clk frequencies or moving
 defines for the number of clks out of DT binding headers into the drivers.
 There are even conversions of DT bindings to YAML and migration away from
 strings to describe clk topology. Overall it doesn't look unusual so I expect
 the new drivers to be where we'll have fixes in the coming weeks.

4e2c9cd7dc i2c-for-6.12-rc1
I2C core
 ========
 
 After 15 years of deprecation, the I2C_COMPAT symbol has finally been
 removed. Also client addresses are now locked during initialization to
 prevent race conditions between different kinds of instantiation. Scoped
 foreach OF child loops are now used. And the testunit has received some
 cleanups and documentation improvements as well as two new tests, one
 for repeated start and one for triggering SMBusAlert interrupts.
 
 I2C host drivers
 ================
 
 The DesignWare and the Renesas I2C drivers have received most of
 the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045
     - Rockchip RK3576
     - KEBA I2C
     - Theobroma Systems Mule Multiplexer.
 
 The Keba comes with a new driver, i2c-keba.c.
 The Mule is an i2c multiplexer and it also comes with a new
 driver, mux/i2c-mux-mule.c.
 
 Core patch
 ----------
 This pull request includes also a patch in the I2C framework, in
 i2c-core-base.c where the runtime PM functions have been replaced
 in order to allow to be accessed during the device add.
 
 Devicetree
 ----------
 Some cleanups in the devicetree, as well. nVidia and Qualcomm
 bindings improve their "if:then:" blocks. While the aspeed
 binding loses the "multi-master" property because it was
 redundant.
 
 The i2c-sprd binding has been converted to YAML.

   - finally remove the I2C_COMPAT symbol after 15 years of deprecation

   - lock client addresses during initialization to prevent race
     conditions between different kinds of instantiation

   - use scoped foreach OF child loops

   - testunit cleanups and documentation improvements, as well as two
     new tests, one for repeated start and one for triggering SMBusAlert
     interrupts

  I2C host drivers:

   - DesignWare and Renesas I2C driver updates.

     The first has has undergone through a series of cleanups that have
     been sent to the mailing list a year ago for the first time and
     finally get merged in this pull request. They are many, from typos
     (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
     functions to librarieas) and many others.

   - all the DesignWare Kconfig options have been grouped under the
     I2C_DESIGNWARE_CORE and this required some adaptation in many of
     the kernel configuration files for different arm and mips boards

  Cleanups:

   - improve the exit path in the runtime resume function for the
     Qualcomm Geni platform

   - get rid of the unused "target_addr" parameter in the Intel LJCA
     driver

   - intialize the restart_flag in the MediaTek controller in one single
     place

   - constify a few global data structures in the virtio driver

   - simplify the bus speed handling in the Renesas driver init function
     making it more readable

   - improved probe function of the Renesas R-Car driver

   - switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
     SET_RUNTIME_PM_OPS()

   - iMX/MXC driver cleanups

   - use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
     and MPC drivers

  Refactoring:

   - Fix a potential out of boundary array access in the Nuvoton driver.

     This is not a bug fix because the issue could never occur due to
     hardware not having the properties listed in the array. The change
     makes the driver more future proof and, at the same time, silences
     code analyzers.

  Improvements:

   - several patches improving the runtime power management handling of
     the Renesas I2C (riic) driver

   - use a more descriptive adapter name in the Intel i801 driver to
     show the presence of the IDF feature

   - kill pending transactions when irq's can't complete their handling
     in the Intel Denverton (ismt) driver, triggering a timeout

  New Feature:

   - support fast mode plus in the Renesas I2C (riic) driver

  New support:

   - Added support for:
      - Renesas R9A08G045
      - Rockchip RK3576
      - KEBA I2C
      - Theobroma Systems Mule Multiplexer.

   - new i2c-keba.c driver

   - new driver for The Mule i2c multiplexer

  Core I2C framework:

   - move runtime PM functions in order to allow them to be accessed
     during device add

  Devicetree:

   - nVidia and Qualcomm binding improvements

   - get rid of redundant "multi-master" property in the aspeed binding

   - convert i2c-sprd binding to YAML

  AT24 updates:

  - document a new model from giantec in DT bindings"

d7dfb07d4d firewire updates for v6.12
The batch of changes includes the followwing:
 
 - Replacing tasklet with usual workqueue for isochronous context
 - Replacing IDR with XArray
 - Utilizing guard macro where possible
 - Printing deprecation warning when enabling debug parameter of
   firewire-ohci module
 
 Additionally, it includes a single patch for sound subsystem which the
 subsystem maintainer acked:
 
 - Switching to nonatomic PCM operation
 
 In FireWire subsystem, tasklet has been used as the bottom half of 1394
 OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
 been available, and some developers have proposed replacing tasklet with
 BH workqueue. While it is fortunate that developers are still considering
 the legacy subsystem, a simple replacement is not necessarily suitable.
 
 As a first step towards dropping tasklet, I've investigated the
 feasibility for 1394 OHCI isochronous context, and concluded that usual
 workqueue is available. In the context, the batch of packets is processed
 in the specific queue, thus the timing jitter caused by task scheduling is
 not so critical. Additionally, DMA transmission can be scheduled
 per-packet basis, therefore the context can be sleep between the operation
 of transmissions. Furthermore, in-kernel protocol implementation involves
 some CPU-bound tasks, which can sometimes consumes CPU time so long. These
 characteristics suggest that usual workqueue is suitable, through BH
 workqueues are not.
 
 The replacement with usual workqueue allows unit drivers to process the
 content of packets in non-atomic context. It brings some reliefs to some
 drivers in sound subsystem that spin-lock is not mandatory anymore during
 isochronous packet processing.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Wait for device readiness after reset by polling Vendor ID and
     looking for Configuration RRS instead of polling the Command
     register and looking for non-error completions, to avoid hardware
     retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

   - Rename CRS Completion Status to RRS ('Request Retry Status') to
     match PCIe r6.0 spec usage (Bjorn Helgaas)

     retrain a link when there's no downstream device anymore (Maciej W.
     Rozycki)

   - Revert to the original link speed after retraining fails instead of
     leaving it restricted to 2.5GT/s, so a future device has a chance
     to use higher speeds (Maciej W. Rozycki)

   - Wait for each level of downstream bus, not just the first, to
     become accessible before restoring devices on that bus (Ilpo
     Järvinen)

     implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
     mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
     xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'

     clocks (Krzysztof Kozlowski)

  Altera PCIe controller driver:

     thing and is what other drivers use (Jinjie Ruan)

  Broadcom STB PCIe controller driver:

     statements (Frank Li)

   - Expand comments for erratum ERR010728 workaround (Frank Li)

b3f391fddf bcachefs changes for 6.12-rc1
rcu_pending, btree key cache rework: this solves lock contenting in the
 key cache, eliminating the biggest source of the srcu lock hold time
 warnings, and drastically improving performance on some metadata heavy
 workloads - on multithreaded creates we're now 3-4x faster than xfs.
 
 We're now using an rhashtable instead of the system inode hash table;
 this is another significant performance improvement on multithreaded
 metadata workloads, eliminating more lock contention.
 
 for_each_btree_key_in_subvolume_upto(): new helper for iterating over
 keys within a specific subvolume, eliminating a lot of open coded
 "subvolume_get_snapshot()" and also fixing another source of srcu lock
 time warnings, by running each loop iteration in its own transaction (as
 the existing for_each_btree_key() does).
 
 More work on btree_trans locking asserts; we now assert that we don't
 hold btree node locks when trans->locked is false, which is important
 because we don't use lockdep for tracking individual btree node locks.
 
 Some cleanups and improvements in the bset.c btree node lookup code,
 from Alan.
 
 Rework of btree node pinning, which we use in backpointers fsck. The old
 hacky implementation, where the shrinker just skipped over nodes in the
 pinned range, was causing OOMs; instead we now use another shrinker with
 a much higher seeks number for pinned nodes.
 
 Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue
 where rebalance would sometimes fall back to allocating from the full
 filesystem, which is not what we want when it's trying to move data to a
 specific target.
 
 Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache
 allocations.
 
 Idmap mounts are now supported - Hongbo.
 
 Rename whiteouts are now supported - Hongbo.
 
 Erasure coding can now handle devices being marked as failed, or
 forcibly removed. We still need the evacuate path for erasure coding,
 but it's getting very close to ready for people to start using.
 
 Status, and when will we be taking off experimental:
 ----------------------------------------------------
 
 Going by critical, user facing bugs getting found and fixed, we're
 nearly there. There are a couple key items that need to be finished
 before we can take off the experimental label:
 
 - The end-user experience is still pretty painful when the root
   filesystem needs a fsck; we need some form of limited self healing so
   that necessary repair gets run automatically. Errors (by type) are
   recorded in the superblock, so what we need to do next is convert
   remaining inconsistent() errors to fsck() errors (so that all runtime
   inconsistencies are logged in the superblock), and we need to go
   through the list of fsck errors and classify them by which fsck passes
   are needed to repair them.
 
 - We need comprehensive torture testing for all our repair paths, to
   shake out remaining bugs there. Thomas has been working on the tooling
   for this, so this is coming soonish.
 
 Slightly less critical items:
 
 - We need to improve the end-user experience for degraded mounts: right
   now, a degraded root filesystem means dropping to an initramfs shell
   or somehow inputting mount options manually (we don't want to allow
   degraded mounts without some form of user input, except on unattended
   servers) - we need the mount helper to prompt the user to allow
   mounting degraded, and make sure this works with systemd.
 
 - Scalabiity: we have users running 100TB+ filesystems, and that's
   effectively the limit right now due to fsck times. We have some
   reworks in the pipeline to address this, we're aiming to make petabyte
   sized filesystems practical.

f8eb5bd9a8 mm: fix build on 32-bit targets without MAX_PHYSMEM_BITS
The merge resolution to deal with the conflict between commits
ea72ce5da2 ("x86/kaslr: Expose and use the end of the physical memory
address space") and 99185c10d5 ("resource, kunit: add test case for
region_intersects()") ended up being broken in configurations didn't
define a MAX_PHYSMEM_BITS and that had a 32-bit 'phys_addr_t'.

The fallback to using all bits set (ie "(-1ULL)") ended up causing a
build error:

    kernel/resource.c: In function ‘gfr_start’:
    include/linux/minmax.h:93:30: error: conversion from ‘long long unsigned int’ to ‘resource_size_t’ {aka ‘unsigned int’} changes value from ‘18446744073709551615’ to ‘4294967295’ [-Werror=overflow]

this was reported by Geert for m68k, but he points out that it happens
on other 32-bit architectures too, eg mips, xtensa, parisc, and powerpc.

Limiting 'PHYSMEM_END' to a 'phys_addr_t' (which is the same as
'resource_size_t') fixes the build, but Geert points out that it will
then cause a silent overflow in mm/sparse.c:

	unsigned long max_sparsemem_pfn = (PHYSMEM_END + 1) >> PAGE_SHIFT;

so we actually do want PHYSMEM_END to be defined a 64-bit type - just
not all ones, and not larger than 'phys_addr_t'.

The proper fix is probably to not have some kind of default fallback at
all, but just make sure every architecture has a valid MAX_PHYSMEM_BITS.
But in the meantime, this just applies the rule that PHYSMEM_END is the
largest value that fits in a 'phys_addr_t', but does not have the high
bit set in 64 bits.

Ugly, ugly.

d0dd066a0f seqcount: replace smp_rmb() in read_seqcount() with load acquire
Many architectures support load acquire which can replace a memory
barrier and save some cycles.

A typical sequence

	do {
		seq = read_seqcount_begin(&s);
		<something>
	} while (read_seqcount_retry(&s, seq);

requires 13 cycles on an N1 Neoverse arm64 core (Ampere Altra, to be
specific) for an empty loop.  Two read memory barriers are needed.  One
for each of the seqcount_* functions.

We can replace the first read barrier with a load acquire of the
seqcount which saves us one barrier.

On the Altra doing so reduces the cycle count from 13 to 8.

According to ARM, this is a general improvement for the ARM64
architecture and not specific to a certain processor.

See

  https://developer.arm.com/documentation/102336/0100/Load-Acquire-and-Store-Release-instructions

 "Weaker ordering requirements that are imposed by Load-Acquire and
  Store-Release instructions allow for micro-architectural
  optimizations, which could reduce some of the performance impacts that
  are otherwise imposed by an explicit memory barrier.

  If the ordering requirement is satisfied using either a Load-Acquire
  or Store-Release, then it would be preferable to use these
  instructions instead of a DMB"

[ NOTE! This is my original minimal patch that unconditionally switches
  over to using smp_load_acquire(), instead of the much more involved
  and subtle patch that Christoph Lameter wrote that made it
  conditional.

  But Christoph gets authorship credit because I had initially thought
  that we needed the more complex model, and Christoph ran with it it
  and did the work. Only after looking at code generation for all the
  relevant architectures, did I come to the conclusion that nobody
  actually really needs the old "smp_rmb()" model.

  Even architectures without load-acquire support generally do as well
  or better with smp_load_acquire().

  So credit to Christoph, but if this then causes issues on other
  architectures, put the blame solidly on me.

  Also note as part of the ruthless simplification, this gets rid of the
  overly subtle optimization where some code uses a non-barrier version
  of the sequence count (see the __read_seqcount_begin() users in
  fs/namei.c). They then play games with their own barriers and/or with
  nested sequence counts.

  Those optimizations are literally meaningless on x86, and questionable
  elsewhere. If somebody can show that they matter, we need to re-do
  them more cleanly than "use an internal helper".       - Linus ]

de5cb0dcb7 Merge branch 'address-masking'
Merge user access fast validation using address masking.

This allows architectures to optionally use a data dependent address
masking model instead of a conditional branch for validating user
accesses.  That avoids the Spectre-v1 speculation barriers.

Right now only x86-64 takes advantage of this, and not all architectures
will be able to do it.  It requires a guard region between the user and
kernel address spaces (so that you can't overflow from one to the
other), and an easy way to generate a guaranteed-to-fault address for
invalid user pointers.

Also note that this currently assumes that there is no difference
between user read and write accesses.  If extended to architectures like
powerpc, we'll also need to separate out the user read-vs-write cases.

* address-masking:
  x86: make the masked_user_access_begin() macro use its argument only once
  x86: do the user address masking outside the user access area
  x86: support user address masking instead of non-speculative conditional

af9c191ac2 ring-buffer: Updates for v6.12:
- Merged v6.11-rc3 into trace/ring-buffer/core
 
   The v6.10 ring buffer pull request was not made due to Mathieu Desnoyers
   making a comment to the pull request. Mathieu and I resolved it on IRC,
   but we did not let Linus know that it was resolved. Linus did not do the
   pull thinking it still had some unresolved issues.
 
   The ring buffer work for 6.12 was dependent on both this pull request as
   well as the reserve_mem kernel command line option that was going upstream
   through the memory management tree. The ring buffer repo was being used by
   others so it could not be rebased. In order to continue the work, the
   v6.11-rc3 branch was pulled in to get access to the reserve_mem work.
 
 This has the 6.11 pull request that did not make it into 6.11, which was:
 
   tracing/ring-buffer: Have persistent buffer across reboots
 
   This allows for the tracing instance ring buffer to stay persistent across
   reboots. The way this is done is by adding to the kernel command line:
 
     trace_instance=boot_map@0x285400000:12M
 
   This will reserve 12 megabytes at the address 0x285400000, and then map
   the tracing instance "boot_map" ring buffer to that memory. This will
   appear as a normal instance in the tracefs system:
 
     /sys/kernel/tracing/instances/boot_map
 
   A user could enable tracing in that instance, and on reboot or kernel
   crash, if the memory is not wiped by the firmware, it will recreate the
   trace in that instance. For example, if one was debugging a shutdown of a
   kernel reboot:
 
    # cd /sys/kernel/tracing
    # echo function > instances/boot_map/current_tracer
    # reboot
   [..]
    # cd /sys/kernel/tracing
    # tail instances/boot_map/trace

          swapper/0-1       [000] d..1.   164.549822: acpi_os_write_port <-acpi_reboot
 
   On reboot, the buffer is examined to make sure it is valid. The validation
   check even steps through every event to make sure the meta data of the
   event is correct. If any test fails, it will simply reset the buffer, and
   the buffer will be empty on boot.
 
 The new changes for 6.12 are:
 
 - Allow the tracing persistent boot buffer to use the "reserve_mem" option
 
   Instead of having the admin find a physical address to store the persistent
   buffer, which can be very tedious if they have to administrate several
   different machines, allow them to use the "reserve_mem" option that will
   find a location for them. It is not as reliable because of KASLR, as the
   loading of the kernel in different locations can cause the memory
   allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
   more reliable.
 
 - Have function graph tracer handle offsets from a previous boot.
 
   The ring buffer output from a previous boot may have different addresses
   due to kaslr. Have the function graph tracer handle these by using the
   delta from the previous boot to the new boot address space.
 
 - Only reset the saved meta offset when the buffer is started or reset
 
   In the persistent memory meta data, it holds the previous address space
   information, so that it can calculate the delta to have function tracing
   work. But this gets updated after being read to hold the new address
   space. But if the buffer isn't used for that boot, on reboot, the delta is
   now calculated from the previous boot and not the boot that holds the data
   in the ring buffer. This causes the functions not to be shown. Do not save
   the address space information of the current kernel until it is being
   recorded.
 
 - Add a magic variable to test the valid meta data
 
   Add a magic variable in the meta data that can also be used for
   validation. The validator of the previous buffer doesn't need this magic
   data, but it can be used if the meta data is changed by a new kernel, which
   may have the same format that passes the validator but is used
   differently. This magic number can also be used as a "versioning" of the
   meta data.
 
 - Align user space mapped ring buffer sub buffers to improve TLB entries
 
   Linus mentioned that the mapped ring buffer sub buffers were misaligned
   between the meta page and the sub-buffers, so that if the sub-buffers were
   bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.
 
 - Add new kernel command line "traceoff" to disable tracing on boot for instances
 
   If tracing is enabled for a boot instance, there needs a way to be able to
   disable it on boot so that new events do not get entered into the ring
   buffer and be mixed with events from a previous boot, as that can be
   confusing.
 
 - Allow trace_printk() to go to other instances
 
   Currently, trace_printk() can only go to the top level instance. When
   debugging with a persistent buffer, it is really useful to be able to add
   trace_printk() to go to that buffer, so that you have access to them after
   a crash.
 
 - Do not use "bin_printk()" for traces to a boot instance
 
   The bin_printk() saves only a pointer to the printk format in the ring
   buffer, as the reader of the buffer can still have access to it. But this
   is not the case if the buffer is from a previous boot. If the
   trace_printk() is going to a "persistent" buffer, it will use the slower
   version that writes the printk format into the buffer.
 
 - Add command line option to allow trace_printk() to go to an instance
 
   Allow the kernel command line to define which instance the trace_printk()
   goes to, instead of forcing the admin to set it for every boot via the
   tracefs options.
 
 - Start a document that explains how to use tracefs to debug the kernel
 
 - Add some more kernel selftests to test user mapped ring buffer

   On reboot, the buffer is examined to make sure it is valid. The
   validation check even steps through every event to make sure the meta
   data of the event is correct. If any test fails, it will simply reset
   the buffer, and the buffer will be empty on boot.

 - Allow the tracing persistent boot buffer to use the "reserve_mem"
   option

   Instead of having the admin find a physical address to store the
   persistent buffer, which can be very tedious if they have to
   administrate several different machines, allow them to use the
   "reserve_mem" option that will find a location for them. It is not as
   reliable because of KASLR, as the loading of the kernel in different
   locations can cause the memory allocated to be inconsistent. Booting
   with "nokaslr" can make reserve_mem more reliable.

 - Have function graph tracer handle offsets from a previous boot.

   The ring buffer output from a previous boot may have different
   addresses due to kaslr. Have the function graph tracer handle these
   by using the delta from the previous boot to the new boot address
   space.

 - Only reset the saved meta offset when the buffer is started or reset

   In the persistent memory meta data, it holds the previous address
   space information, so that it can calculate the delta to have
   function tracing work. But this gets updated after being read to hold
   the new address space. But if the buffer isn't used for that boot, on
   reboot, the delta is now calculated from the previous boot and not
   the boot that holds the data in the ring buffer. This causes the
   functions not to be shown. Do not save the address space information
   of the current kernel until it is being recorded.

 - Add a magic variable to test the valid meta data

   Add a magic variable in the meta data that can also be used for
   validation. The validator of the previous buffer doesn't need this
   magic data, but it can be used if the meta data is changed by a new
   kernel, which may have the same format that passes the validator but
   is used differently. This magic number can also be used as a
   "versioning" of the meta data.

 - Align user space mapped ring buffer sub buffers to improve TLB
   entries

   Linus mentioned that the mapped ring buffer sub buffers were
   misaligned between the meta page and the sub-buffers, so that if the
   sub-buffers were bigger than PAGE_SIZE, it wouldn't allow the TLB to
   use bigger entries.

 - Add new kernel command line "traceoff" to disable tracing on boot for
   instances

   If tracing is enabled for a boot instance, there needs a way to be
   able to disable it on boot so that new events do not get entered into
   the ring buffer and be mixed with events from a previous boot, as
   that can be confusing.

 - Allow trace_printk() to go to other instances

   Currently, trace_printk() can only go to the top level instance. When
   debugging with a persistent buffer, it is really useful to be able to
   add trace_printk() to go to that buffer, so that you have access to
   them after a crash.

 - Do not use "bin_printk()" for traces to a boot instance

   The bin_printk() saves only a pointer to the printk format in the
   ring buffer, as the reader of the buffer can still have access to it.
   But this is not the case if the buffer is from a previous boot. If
   the trace_printk() is going to a "persistent" buffer, it will use the
   slower version that writes the printk format into the buffer.

 - Add command line option to allow trace_printk() to go to an instance

   Allow the kernel command line to define which instance the
   trace_printk() goes to, instead of forcing the admin to set it for
   every boot via the tracefs options.

 - Start a document that explains how to use tracefs to debug the kernel

 - Add some more kernel selftests to test user mapped ring buffer

88264981f2 sched_ext: Initial pull request for v6.12
This is the initial pull request of sched_ext. The v7 patchset
 (https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
 applied on top of tip/sched/core + bpf/master as of Jun 18th.
 
   tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
 ble")
   bpf/master f6afdaf72a ("Merge branch 'bpf-support-resilient-split-btf'")
 
 Since then, the following pulls were made:
 
 - v6.11-rc1 is pulled to keep up with the mainline.
 
 - tip/sched/core was pulled several times:
 
   - 7b9f6c864a, 0df340ceae, 5ac998574f, 0b1777f0fa: To resolve
     conflicts. See each commit for details on conflicts and their
     resolutions.
 
   - d7b01aef9d: To receive fd03c5b858 ("sched: Rework pick_next_task()")
     and related commits. @prev in added to sched_class->put_prev_task() and
     put_prev_task() is reordered after ->pick_task(), which makes
     sched_class->switch_class() unnecessary. The follow-up commits update
     sched_ext accordingly and drop sched_class->switch_class().
 
 - bpf/master was pulled to receive baebe9aaba ("bpf: allow passing struct
   bpf_iter_<type> as kfunc arguments") and related changes in preparation
   for the DSQ iterator patchset
 
 To obtain the net sched_ext changes, diff against:
 
   git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.12-base
 
 which is the merge of:
 
   tip/sched/core bc9057da1a ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
   bpf/master 2ad6d23f46 ("selftests/bpf: Do not update vmlinux.h unnecessarily")
 
 Since the v7 patchset, the following changes were made:
 
 - cpuperf support which was a part of the v6 patchset was posted separately
   and then applied after reviews.
 
 - cgroup support which was a part of the v6 patchset was posted seprately,
   iterated and then applied.
 
 - Improve integration with sched core.
 
 - Double locking usage in migration paths dropped. Depend on
   TASK_ON_RQ_MIGRATING synchronization instead.
 
 - The BPF scheduler couldn't directly dispatch to the local DSQ of another
   CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
   handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
   in the enqueue path too.
 
 - DSQ iterator which was a part of the v6 patchset was posted separately.
   The iterator itself was applied after a couple revisions. The associated
   selective consumption kfunc can use further improvements and is still
   being worked on.
 
 - scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
   can now be transferred between two DSQs from almost any context. This
   involved significant refactoring of migration code.
 
 - Various fixes and improvements.
 
 As the branch is based on top of tip/sched/core + bpf/master, please merge
 after both are applied.

Pull sched_ext support from Tejun Heo:
 "This implements a new scheduler class called ‘ext_sched_class’, or
  sched_ext, which allows scheduling policies to be implemented as BPF
  programs.

  The goals of this are:

   - Ease of experimentation and exploration: Enabling rapid iteration
     of new scheduling policies.

   - Customization: Building application-specific schedulers which
     implement policies that are not applicable to general-purpose
     schedulers.

   - Rapid scheduler deployments: Non-disruptive swap outs of scheduling
     policies in production environments"

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next

Pull bpf updates from Alexei Starovoitov:

 - Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
   corresponding support in LLVM.

   It is similar to existing 'no_caller_saved_registers' attribute in
   GCC/LLVM with a provision for backward compatibility. It allows
   compilers generate more efficient BPF code assuming the verifier or
   JITs will inline or partially inline a helper/kfunc with such
   attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
   bpf_get_smp_processor_id are the first set of such helpers.

 - Harden and extend ELF build ID parsing logic.

   When called from sleepable context the relevants parts of ELF file
   will be read to find and fetch .note.gnu.build-id information. Also
   harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.

 - Improvements and fixes for sched-ext:
    - Allow passing BPF iterators as kfunc arguments
    - Make the pointer returned from iter_next method trusted
    - Fix x86 JIT convergence issue due to growing/shrinking conditional
      jumps in variable length encoding

 - BPF_LSM related:
    - Introduce few VFS kfuncs and consolidate them in
      fs/bpf_fs_kfuncs.c
    - Enforce correct range of return values from certain LSM hooks
    - Disallow attaching to other LSM hooks

 - Prerequisite work for upcoming Qdisc in BPF:
    - Allow kptrs in program provided structs
    - Support for gen_epilogue in verifier_ops

 - Important fixes:
    - Fix uprobe multi pid filter check
    - Fix bpf_strtol and bpf_strtoul helpers
    - Track equal scalars history on per-instruction level
    - Fix tailcall hierarchy on x86 and arm64
    - Fix signed division overflow to prevent INT_MIN/-1 trap on x86
    - Fix get kernel stack in BPF progs attached to tracepoint:syscall

 - Selftests:
    - Add uprobe bench/stress tool
    - Generate file dependencies to drastically improve re-build time
    - Match JIT-ed and BPF asm with __xlated/__jited keywords
    - Convert older tests to test_progs framework
    - Add support for RISC-V
    - Few fixes when BPF programs are compiled with GCC-BPF backend
      (support for GCC-BPF in BPF CI is ongoing in parallel)
    - Add traffic monitor
    - Enable cross compile and musl libc

this pull request are:
 
 "Align kvrealloc() with krealloc()" from Danilo Krummrich.  Adds
 consistency to the APIs and behaviour of these two core allocation
 functions.  This also simplifies/enables Rustification.
 
 "Some cleanups for shmem" from Baolin Wang.  No functional changes - mode
 code reuse, better function naming, logic simplifications.
 
 "mm: some small page fault cleanups" from Josef Bacik.  No functional
 changes - code cleanups only.
 
 "Various memory tiering fixes" from Zi Yan.  A small fix and a little
 cleanup.
 
 "mm/swap: remove boilerplate" from Yu Zhao.  Code cleanups and
 simplifications and .text shrinkage.
 
 "Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt.  This
 is a feature, it adds new feilds to /proc/vmstat such as
 
     $ grep kstack /proc/vmstat
     kstack_1k 3
     kstack_2k 188
     kstack_4k 11391
     kstack_8k 243
     kstack_16k 0
 
 which tells us that 11391 processes used 4k of stack while none at all
 used 16k.  Useful for some system tuning things, but partivularly useful
 for "the dynamic kernel stack project".
 
 "kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
 Teaches kmemleak to detect leaksage of percpu memory.
 
 "mm: memcg: page counters optimizations" from Roman Gushchin.  "3
 independent small optimizations of page counters".
 
 "mm: split PTE/PMD PT table Kconfig cleanups+clarifications" from David
 Hildenbrand.  Improves PTE/PMD splitlock detection, makes powerpc/8xx work
 correctly by design rather than by accident.
 
 "mm: remove arch_make_page_accessible()" from David Hildenbrand.  Some
 folio conversions which make arch_make_page_accessible() unneeded.
 
 "mm, memcg: cg2 memory{.swap,}.peak write handlers" fro David Finkel.
 Cleans up and fixes our handling of the resetting of the cgroup/process
 peak-memory-use detector.
 
 "Make core VMA operations internal and testable" from Lorenzo Stoakes.
 Rationalizaion and encapsulation of the VMA manipulation APIs.  With a
 view to better enable testing of the VMA functions, even from a
 userspace-only harness.

 some missing info in /proc/zoneinfo.
 
 "mm: replace follow_page() by folio_walk" from David Hildenbrand.  Code
 cleanups and rationalizations (conversion to folio_walk()) resulting in
 the removal of follow_page().
 
 "improving dynamic zswap shrinker protection scheme" from Nhat Pham.  Some
 tuning to improve zswap's dynamic shrinker.  Significant reductions in
 swapin and improvements in performance are shown.
 
 "mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
 Improvements to the new unaccepted memory feature,
 
 "mm/mprotect: Fix dax puds" from Peter Xu.  Implements mprotect on DAX
 PUDs.  This was missing, although nobody seems to have notied yet.
 
 "Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
 Cleanups and modest performance improvements for the maple tree library
 code.
 
 "memcg: further decouple v1 code from v2" from Shakeel Butt.  Move more
 cgroup v1 remnants away from the v2 memcg code.
 
 "memcg: initiate deprecation of v1 features" from Shakeel Butt.  Adds
 various warnings telling users that memcg v1 features are deprecated.

 improves the performance of munmap() of swap-filled ptes.
 
 "support large folio swap-out and swap-in for shmem" from Baolin Wang.
 With this series we no longer split shmem large folios into simgle-page
 folios when swapping out shmem.
 
 "mm/hugetlb: alloc/free gigantic folios" from Yu Zhao.  Nice performance
 improvements and code reductions for gigantic folios.
 
 "support shmem mTHP collapse" from Baolin Wang.  Adds support for
 khugepaged's collapsing of shmem mTHP folios.

c24999e61b The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045

Merge tag 'i2c-host-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.

The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.

Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.

Follows the list of the rest of the changes grouped by type of
change.

Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.

The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.

The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.

Constified a few global data structures in the virtio driver.

The Renesas driver simplifies the bus speed handling in the init
function making it more readable.

Improved an if/else statement in probe function of the Renesas
R-Car driver.

The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().

Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.

Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.

Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.

Improvements
------------
The Renesas I2C (riic) driver undergoes several patches improving
the runtime power management handling.

The Intel i801 driver uses a more descriptive adapter's name to
show the presence of the IDF feature.

In the Intel Denverton (ismt) adapter the pending transactions
are killed when irq's can't complete their handling, triggering a
timeout. This could have been considered as a bug fix, but
because, standing to Vasily, it's very sporadic, I preferred
considering the patch rather as an improvement.

New Feature
-----------
The Renesas I2C (riic) driver now supports the fast mode plus.

New support
-----------
Added support for:

    - Renesas R9A08G045
    - Rockchip RK3576
    - KEBA I2C
    - Theobroma Systems Mule Multiplexer.

The Keba comes with a new driver, i2c-keba.c.
The Mule is an i2c multiplexer and it also comes with a new
driver, mux/i2c-mux-mule.c.

Core patch
----------
This pull request includes also a patch in the I2C framework, in
i2c-core-base.c where the runtime PM functions have been replaced
in order to allow to be accessed during the device add.

----------

binding loses the "multi-master" property because it was
redundant.

Merge tag 'vfs-6.12.blocksize' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull vfs blocksize updates from Christian Brauner:
 "This contains the vfs infrastructure as well as the xfs bits to enable
  support for block sizes (bs) larger than page sizes (ps) plus a few
  fixes to related infrastructure.

  There has been efforts over the last 16 years to enable enable Large
  Block Sizes (LBS), that is block sizes in filesystems where bs > page
  size. Through these efforts we have learned that one of the main
  blockers to supporting bs > ps in filesystems has been a way to
  allocate pages that are at least the filesystem block size on the page
  cache where bs > ps.

  Thanks to various previous efforts it is possible to support bs > ps
  in XFS with only a few changes in XFS itself. Most changes are to the
  page cache to support minimum order folio support for the target block
  size on the filesystem.

  A motivation for Large Block Sizes today is to support high-capacity
  (large amount of Terabytes) QLC SSDs where the internal Indirection
  Unit (IU) are typically greater than 4k to help reduce DRAM and so in
  turn cost and space. In practice this then allows different
  architectures to use a base page size of 4k while still enabling
  support for block sizes aligned to the larger IUs by relying on high
  order folios on the page cache when needed.

  It also allows to take advantage of the drive's support for atomics
  larger than 4k with buffered IO support in Linux. As described this
  year at LSFMM, supporting large atomics greater than 4k enables
  databases to remove the need to rely on their own journaling, so they
  can disable double buffered writes, which is a feature different cloud
  providers are already enabling through custom storage solutions"

4b132aacb0 tools: Add xdrgen
Add a Python-based tool for translating XDR specifications into XDR
encoder and decoder functions written in the Linux kernel's C coding
style. The generator attempts to match the usual C coding style of
the Linux kernel's SunRPC consumers.

This approach is similar to the netlink code generator in
tools/net/ynl .

The maintainability benefits of machine-generated XDR code include:

- Stronger type checking
- Reduces the number of bugs introduced by human error
- Makes the XDR code easier to audit and analyze
- Enables rapid prototyping of new RPC-based protocols
- Hardens the layering between protocol logic and marshaling
- Makes it easier to add observability on demand
- Unit tests might be built for both the tool and (automatically)
  for the generated code

In addition, converting the XDR layer to use memory-safe languages
such as Rust will be easier if much of the code can be converted
automatically.

36ffa3d0de nfsd: be more systematic about selecting error codes for internal use.
Rather than using ad hoc values for internal errors (30000, 11000, ...)
use 'enum' to sequentially allocate numbers starting from the first
known available number - now visible as NFS4ERR_FIRST_FREE.

The goal is values that are distinct from all be32 error codes.  To get
those we must first select integers that are not already used, then
convert them with cpu_to_be32().

3391fc92db sunrpc: allow svc threads to fail initialisation cleanly
If an svc thread needs to perform some initialisation that might fail,
it has no good way to handle the failure.

Before the thread can exit it must call svc_exit_thread(), but that
requires the service mutex to be held.  The thread cannot simply take
the mutex as that could deadlock if there is a concurrent attempt to
shut down all threads (which is unlikely, but not impossible).

nfsd currently call svc_exit_thread() unprotected in the unlikely event
that unshare_fs_struct() fails.

We can clean this up by introducing svc_thread_init_status() by which an
svc thread can report whether initialisation has succeeded.  If it has,
it continues normally into the action loop.  If it has not,
svc_thread_init_status() immediately aborts the thread.
svc_start_kthread() waits for either of these to happen, and calls
svc_exit_thread() (under the mutex) if the thread aborted.

60749cbe3d sunrpc: change sp_nrthreads from atomic_t to unsigned int.
sp_nrthreads is only ever accessed under the service mutex
  nlmsvc_mutex nfs_callback_mutex nfsd_mutex
so these is no need for it to be an atomic_t.

The fact that all code using it is single-threaded means that we can
simplify svc_pool_victim and remove the temporary elevation of
sp_nrthreads.

      - Clean up DL server vs. core sched
      - Split up put_prev_task_balance()
      - Rework pick_next_task()
      - Combine the last put_prev_task() and the first set_next_task()
      - Rework dl_server
      - Add put_prev_task(.next)
 
       (Peter Zijlstra, with a fix by Tejun Heo)
 
  - Complete the EEVDF transition and refine EEVDF scheduling:

      - Allow shorter slices to wakeup-preempt
      - Use sched_attr::sched_runtime to set request/slice suggestion
      - Document the new feature flags
      - Remove unused and duplicate-functionality fields
      - Simplify & unify pick_next_task_fair()
      - Misc debuggability enhancements
 
       (Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann,
        Valentin Schneider and Chuyi Zhou)
 
  - Initialize the vruntime of a new task when it is first enqueued,

Pull scheduler updates from Ingo Molnar:

 - Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot
   de Oliveira's last major contribution to the kernel:

     "SCHED_DEADLINE servers can help fixing starvation issues of low
      priority tasks (e.g., SCHED_OTHER) when higher priority tasks
      monopolize CPU cycles. Today we have RT Throttling; DEADLINE
      servers should be able to replace and improve that."

   (Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes, Youssef
   Esmat, Huang Shijie)

 - Preparatory changes for sched_ext integration:
     - Use set_next_task(.first) where required
     - Fix up set_next_task() implementations
     - Clean up DL server vs. core sched
     - Split up put_prev_task_balance()
     - Rework pick_next_task()
     - Combine the last put_prev_task() and the first set_next_task()
     - Rework dl_server
     - Add put_prev_task(.next)

   (Peter Zijlstra, with a fix by Tejun Heo)

 - Complete the EEVDF transition and refine EEVDF scheduling:
     - Implement delayed dequeue
     - Allow shorter slices to wakeup-preempt
     - Use sched_attr::sched_runtime to set request/slice suggestion
     - Document the new feature flags
     - Remove unused and duplicate-functionality fields
     - Simplify & unify pick_next_task_fair()
     - Misc debuggability enhancements

   (Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann, Valentin
   Schneider and Chuyi Zhou)

 - Initialize the vruntime of a new task when it is first enqueued,
   resulting in significant decrease in latency of newly woken tasks
   (Zhang Qiao)

 - Introduce SM_IDLE and an idle re-entry fast-path in __schedule()
   (K Prateek Nayak, Peter Zijlstra)

 - Clean up and clarify the usage of Clean up usage of rt_task()
   (Qais Yousef)

 - Preempt SCHED_IDLE entities in strict cgroup hierarchies
   (Tianchen Ding)

 - Clarify the documentation of time units for deadline scheduler
   parameters (Christian Loehle)

 - Remove the HZ_BW chicken-bit feature flag introduced a year ago,
   the original change seems to be working fine (Phil Auld)

 - Misc fixes and cleanups (Chen Yu, Dan Carpenter, Huang Shijie,
   Peilin He, Qais Yousefm and Vincent Guittot)

a1d1eb2f57 SCSI misc on 20240919
Updates to the usual drivers (ufs, smartpqi, NCR5380, mac_scsi, lpfc,
 mpi3mr).  There are no user visible core changes and a whole series of
 minor updates and fixes.  The largest core change is probably the
 simplification of the workqueue allocation path.

  come to mind.

 "DT Bindings:

   - Drop duplicate devices in trivial-devices.yaml

   - Add a common serial peripheral device schema and reference it in
     serial device schemas.

   - Convert nxp,lpc1850-wdt, zii,rave-wdt, ti,davinci-wdt,
     snps,archs-pct, fsl,bcsr, fsl,fpga-qixis-i2c, fsl,fpga-qixis,
     fsl,cpm-enet, fsl,cpm-mdio, fsl,ucc-hdlc, maxim,ds26522,
     aspeed,ast2400-cvic, aspeed,ast2400-vic, fsl,ftm-timer,
     ti,davinci-timer, fsl,rcpm, and qcom,ebi2 to DT schema

   - Add support for rockchip,rk3576-wdt, qcom,apss-wdt-sa8255p,
     fsl,imx8qm-irqsteer, qcom,pm6150-vib, qcom,sa8255p-pdc,
     isil,isl69260, ti,tps546d24, and lpc32xx DMA mux

   - Drop duplicate nvidia,tegra186-ccplex-cluster.yaml and
     mediatek,mt6795-sys-clock.yaml

   - Add arm,gic ESPI and EPPI interrupt type specifiers

   - Add another batch of legacy compatible strings which we have no
     intention of documenting

   - Add dmas/dma-names properties to FSL lcdif

   - Fix wakeup-source reference to m8921-keypad.yaml

   - Treewide fixes of typos in bindings

  DT Core:

   - Update dtc/libfdt to upstream version v1.7.0-95-gbcd02b523429

   - More conversions to scoped iterators and __free() initializer

   - Handle overflows in address resources on 32-bit systems

   - Extend extracting compatible strings in sources from function
     parameters

   - Use of_property_present() in DT unittest

   - Clean-up of_irq_to_resource() to use helpers

   - Support #msi-cells=<0> in of_msi_get_domain()

   - Improve the kerneldoc for of_property_match_string()

   - kselftest: Ignore nodes that have ancestors disabled"
