This series provides KCSAN fixes and also the ability to take memory
barriers into account for weakly-ordered systems. This last can increase
the probability of detecting certain types of data races.

"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.

drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.

Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification

"Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible, or at
least perform the freeing outside of the socket lock section to
decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice and
net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top
box based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908.

Pull clocksource watchdog updates from Paul McKenney:
- Avoid accidental unstable marking of clocksources by rejecting
clocksource measurements where the source of the skew is the delay
reading reference clocksource itself. This change avoids many of the
current false positives caused by epic cache-thrashing workloads.
- Reduce the default clocksource_watchdog() retries to 2, thus offsetting
the increased overhead due to #1 above rereading the reference
clocksource.

As has been discussed some time ago on ksumitt-discuss@ mailinglist,
the need for trivial tree diminished over time as all the tooling and
processess became much more mature and it's quite natural these days
for trivial patches to flow through subsystem trees anyway, so the
spin-off of a trivial tree doesn't make sense any more, and is not worth
the merge conflicts it might sometimes create.
So remove any mentions of it from kernel documentation for good.

sysfs documentation is supposed to go in Documentation/ABI/.
However, /sys/block/<disk>/queue/* are documented in
Documentation/block/queue-sysfs.rst, and sometimes redundantly in
Documentation/ABI/stable/sysfs-block too.
Let's consolidate this documentation into Documentation/ABI/.
Therefore, copy the relevant docs from queue-sysfs.rst into sysfs-block.
This primarily means adding the 25 missing files that were documented in
queue-sysfs.rst only, as well as mentioning the RO/RW status of files.
Documentation/ABI/ requires "Date" and "Contact" fields. For the Date
fields, I used the date of the commit which added support for each file.
For the "Contact" fields, I used linux-block.

Sort the documentation for the files alphabetically by file path so that
there is a logical order and it's clear where to add new files.
With two small exceptions, this patch doesn't change the documentation
itself and just reorders it:
- In /sys/block/<disk>/<part>/stat, I replaced <part> with <partition>
to be consistent with the other files.
- The description for /sys/block/<disk>/<part>/stat referred to another
file "above", which I reworded.

With 'unevaluatedProperties' support implemented, the properties
'snps,pbl', 'snps,txpbl', and 'snps,rxpbl' are not allowed in the
examples for some of the DWMAC versions:
Documentation/devicetree/bindings/net/intel,dwmac-plat.example.dt.yaml: ethernet@3a000000: Unevaluated properties are not allowed ('snps,pbl', 'mdio0' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@5800a000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@40028000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)
Documentation/devicetree/bindings/net/stm32-dwmac.example.dt.yaml: ethernet@40027000: Unevaluated properties are not allowed ('reg-names', 'snps,pbl' were unexpected)

This appears to be an oversight, so fix it by allowing the properties
on the v3.50a, v4.10a, and v4.20a versions of the DWMAC.

An MDIO bus can have devices other than ethernet PHYs on it, so it

This converts the Zinitix BT4xx and BT5xx touchscreen bindings to YAML,
fix them up a bit and extends them.
We list all the existing BT4xx and BT5xx components with compatible
strings. These are all similar, use the same bindings and work in
similar ways.
We rename the supplies from the erroneous vdd/vddo to the actual supply
names vcca/vdd as specified on the actual component. It is long
established that supplies shall be named after the supply pin names of a
component. The confusion probably stems from that in a certain product
the rails to the component were named vdd/vddo. Drop some notes on how OS
implementations should avoid confusion by first looking for vddo, and if
that exists assume the legacy binding pair and otherwise use vcca/vdd.
Add reset-gpios as sometimes manufacturers pulls a GPIO line to the reset
line on the chip.
Add optional touchscreen-fuzz-x and touchscreen-fuzz-y properties.

A few more fixes have come in, nothing overly severe but would be good
to get in by final release:
- More specific compatible fields on the qspi controller for socfpga,
to enable quirks in the driver.
- A runtime PM fix for Renesas to fix mismatched reference counts on
errors.

LLQ entry length is 128 bytes. Therefore the maximum header in
the entry is calculated by:
tx_max_header_size =
LLQ_ENTRY_SIZE - DESCRIPTORS_NUM_BEFORE_HEADER * 16 =
128 - 2 * 16 = 96
This patch updates the documentation so that it states the correct
max header length.

KVM_GET_SUPPORTED_CPUID should not include any dynamic xstates in
CPUID[0xD] if they have not been requested with prctl. Otherwise
a process which directly passes KVM_GET_SUPPORTED_CPUID to
KVM_SET_CPUID2 would now fail even if it doesn't intend to use a
dynamically enabled feature. Userspace must know that prctl is
required and allocate >4K xstate buffer before setting any dynamic
bit.

Our documentation encourages the use of list-table formats, but that advice
runs counter to the objective of keeping the plain-text documentation as
useful and readable as possible. Turn that advice around the other way so
that people don't keep adding these tables.
