Pull i2c updates from Wolfram Sang:
 "I2C core:

   - 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"

Pull firewire updates from Takashi Sakamoto:
 "In the FireWire subsystem, tasklets have been used as the bottom half
  of 1394 OHCi hardIRQ. In recent kernel updates, BH workqueues have
  become available, and some developers have proposed replacing the
  tasklet with a BH workqueue.

  As a first step towards dropping tasklet use, the 1394 OHCI
  isochronous context can use regular workqueues. In this 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 normal workqueues are suitable,
  through BH workqueues are not.

  The replacement with a 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.

  Summary:

   - Replace tasklet with workqueue for isochronous context

   - Replace IDR with XArray

   - Utilize guard macro where possible

   - Print deprecation warning when enabling debug parameter of
     firewire-ohci module

   - Switch to nonatomic PCM operation"

     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)

   - Clear LBMS bit after a manual link retrain so we don't try to
     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)

     since host bridges may have several MMIO and I/O port apertures
     (Frank Li)

   - Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
     clocks (Krzysztof Kozlowski)

  Altera PCIe controller driver:

   - Convert altera DT bindings from text to YAML (Matthew Gerlach)

   - Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
     thing and is what other drivers use (Jinjie Ruan)

  Broadcom STB PCIe controller driver:

Pull bcachefs updates from Kent Overstreet:

 - 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 Li)

 - Rename whiteouts are now supported (Hongbo Li)

 - 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.

The merge resolution to deal with the conflict between commits
ea72ce5d ("x86/kaslr: Expose and use the end of the physical memory
address space") and 99185c10 ("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.

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 ]

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

This doesn't actually matter for any of the current users, but before
merging it mainline, make sure we don't have any surprising semantics.

We don't actually want to use an inline function here, because we want
to allow - but not require - const pointer arguments, and return them as
such.  But we already had a local auto-type variable, so let's just use
it to avoid any possible double evaluation.

Pull ring-buffer updates from Steven Rostedt:

 - tracing/ring-buffer: 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

   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

Pull ktest updates from Steven Rostedt:

 - Add notification of build warnings for all tests

   Currently, the build will only fail on warnings if the ktest config
   file states that it should fail or if the compile is done with
   '-Werror'. This has allowed warnings to sneak in if it doesn't fail.

   Add a notification at the end of the test that will state that
   warnings were found in the build so that the developer will be aware
   of it.

 - Fix the grub2 parser to not return the wrong kernel index

   ktest.pl can read the grub.cfg file to know what kernel to boot to
   via grub-reboot. This requires knowing the index that the kernel is
   referenced by in the grub.cfg file. Some distros have logic to
   determine the menuentry that can cause the ktest.pl to come up with
   the wrong index and boot the wrong kernel.
