Pull networking fixes from Jakub Kicinski:
"We have a few fixes for long standing issues, in particular Eric's fix
to not underestimate the skb sizes, and my fix for brokenness of
register_netdevice() error path. They may uncover other bugs so we
will keep an eye on them. Also included are Willem's fixes for
kmap(_atomic).
Looking at the "current release" fixes, it seems we are about one rc
behind a normal cycle. We've previously seen an uptick of "people had
run their test suites" / "humans actually tried to use new features"
fixes between rc2 and rc3.

The bmc150-accel-i2c.c driver has an "_accel" suffix for the
compatibles of BMC150 and BMI055. This is necessary because BMC150
contains both accelerometer (bosch,bmc150_accel) and magnetometer
(bosch,bmc150_magn) and therefore "bosch,bmc150" would be ambiguous.
However, the binding documentation suggests using "bosch,bmc150".
Add the "_accel" suffix for BMC150 and BMI055 so the binding docs
match what is expected by the driver.

Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.
Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.

Arnd found a randconfig that produces the warning:
arch/x86/entry/thunk_64.o: warning: objtool: missing symbol for insn at
offset 0x3e
when building with LLVM_IAS=1 (Clang's integrated assembler). Josh
notes:
With the LLVM assembler not generating section symbols, objtool has no
way to reference this code when it generates ORC unwinder entries,
because this code is outside of any ELF function.
The limitation now being imposed by objtool is that all code must be
contained in an ELF symbol. And .L symbols don't create such symbols.
So basically, you can use an .L symbol *inside* a function or a code
segment, you just can't use the .L symbol to contain the code using a
SYM_*_START/END annotation pair.
Fangrui notes that this optimization is helpful for reducing image size
when compiling with -ffunction-sections and -fdata-sections. I have
observed on the order of tens of thousands of symbols for the kernel
images built with those flags.
A patch has been authored against GNU binutils to match this behavior
of not generating unused section symbols ([1]), so this will
also become a problem for users of GNU binutils once they upgrade to 2.36.
Omit the .L prefix on a label so that the assembler will emit an entry
into the symbol table for the label, with STB_LOCAL binding. This
enables objtool to generate proper unwind info here with LLVM_IAS=1 or
GNU binutils 2.36+.

It's useful to be able to test non-vector event channel delivery, to make
sure Linux will work properly on older Xen which doesn't have it.
It's also useful for those working on Xen and Xen-compatible hypervisors,
because there are guest kernels still in active use which use PCI INTX
even when vector delivery is available.

The current description of ADC keys is not precise enough.
"when this key is pressed" leaves it open if a key is considered pressed
below or above the threshold. This has led to confusion:
drivers/input/keyboard/adc-keys.c ignores the meaning of thresholds and
sets the key that is closest to press-threshold-microvolt.
This patch nails down the definitions and provides an interpretation of the
supplied example.

Before commit 889b8f964f ("packet: Kill CONFIG_PACKET_MMAP.") there
used to be a CONFIG_PACKET_MMAP config symbol that depended on
CONFIG_PACKET. The text still implies that PACKET_MMAP can be disabled.
Remove that from the text, as well as reference to old kernel versions.
Also, drop reference to broken link to information for pre 2.6.5
kernels.
Make a slight working improvement (s/In/On/) while at it.

PMIC pm8009 has special revision (P=1) made for sm8250 platform. The
major difference is the S2 regulator which supplies 0.95 V instead of
2.848V. Add special compatibility string for this chip revision.
The datasheet calls the chip just pm8009-1, so use the same name.

Various fixes to sphinx.rst:
- eliminate a double-space between 2 words
- grammar/wording
- punctuation
- call rows in a table 'rows' instead of 'columns' (or does Sphinx
call everything a column?)
- It seems that "amdfonts" should be "amsfonts". I can't find any
amdfonts.

During the process of converting the documentation to reST, some links
were converted using the following wrong syntax (and sometimes using %20
instead of spaces):
`Display text <#section-name-in-html>`__
This syntax isn't valid according to the docutils' spec [1], but more
importantly, it is specific to HTML, since it uses '#' to link to an
HTML anchor.
The right syntax would instead use a docutils hyperlink reference as the
embedded URI to point to the section [2], that is:
`Display text <Section Name_>`__
This syntax works in both HTML and PDF.
The LaTeX toolchain doesn't mind the HTML anchor syntax when generating
the pdf documentation (make pdfdocs), that is, the build succeeds but
the links don't work, but that syntax causes errors when trying to build
using the not-yet-merged rst2pdf:
ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States'
So, use the correct syntax in order to have it work in all different
output formats.

The API documentation states that general error codes are not detailed, but
errors with specific meanings are. On arm64, KVM_RUN can return error
numbers with a different meaning than what is described by POSIX or the C99
standard (as taken from man 3 errno).
Absent from the newly documented error codes is ERANGE which can be
returned when making a change to the EL2 stage 1 tables if the address is
larger than the largest supported input address. Assuming no bugs in the
implementation, that is not possible because the input addresses which are
mapped are the result of applying the macro kern_hyp_va() on kernel virtual
addresses.

This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, but will still use the concept
of memory granules. Each memory granule maps to a single metadata entry:
8 bytes per one shadow byte for generic mode, 16 bytes per one shadow byte
for software tag-based mode, and 16 bytes per one allocation tag for
hardware tag-based mode.
Rename KASAN_SHADOW_SCALE_SIZE to KASAN_GRANULE_SIZE, and
KASAN_SHADOW_MASK to KASAN_GRANULE_MASK.
Also use MASK when used as a mask, otherwise use SIZE.
No functional changes.

ability to get struct clk pointers from a struct clk_hw so that clk providers
can consume the clks they provide, if they need to do something like that. This
has been a long missing part of the clk provider API that will help us move
away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are
added for the clk_set_rate() "range" functions, similar to the tracepoints we
already have for clk_set_rate() and we added a column to debugfs to help
developers understand the hardware enable state of clks in case firmware or
bootloader state is different than what is expected. Overall the core changes
are mostly improving the clk driver writing experience.
At the driver level, we have the usual collection of driver updates and new
drivers for new SoCs. This time around the Qualcomm folks introduced a good
handful of clk drivers for various parts of three or four SoCs. The SiFive
folks added a new clk driver for their FU740 SoCs, coming in second on the
diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that
for various new features. One last thing to note in the driver area is that the
i.MX driver has gained a new binding to support SCU clks after being on the
list for many months. It uses a two cell binding which is sort of rare in clk
DT bindings. Beyond that we have the usual set of driver fixes and tweaks that
come from more testing and finding out that some configuration was wrong or
that a driver could support being built as a module.
Core:
- Add some trace points for clk_set_rate() "range" functions
- Add hardware enable information to clk_summary debugfs
- Replace clk-provider.h with of_clk.h when possible
- Add devm variant of clk_notifier_register()
- Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
New Drivers:
- Bindings for Canaan K210 SoC clks
- Support for SiFive FU740 PRCI
- Camera clks on Qualcomm SC7180 SoCs
- GCC and RPMh clks on Qualcomm SDX55 SoCs
- RPMh clks on Qualcomm SM8350 SoCs
- LPASS clks on Qualcomm SM8250 SoCs

- Update git repo branch for Renesas clock drivers
- Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
- Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E

The difference between extra-y and always-y is obscure.
Basically, Kbuild builds targets listed in extra-y and always-y in
visited Makefiles without relying on any dependency.
The difference is that extra-y is used to list the targets needed for
vmlinux whereas always-y is used to list the targets that must be always
built irrespective of final targets.
Kbuild skips extra-y when it is building only modules (i.e.
'make modules'). This is the long-standing behavior since extra-y was
introduced in 2003, and it is explained in that commit log [1].
For clarification, this is the extra-y vs always-y table:
extra-y always-y
'make' y y
'make vmlinux' y y
'make modules' n y
Kbuild skips extra-y also when building external modules since obviously
it never builds vmlinux.
Unfortunately, extra-y is wrongly used in many places of upstream code,
and even in external modules.
Using extra-y in external module Makefiles is wrong. What you should
use is probably always-y or 'targets'.
The current documentation for extra-y is misleading. I rewrote it, and
moved it to the section 3.7.
always-y is not documented anywhere. I added.

The two sections "3.10 Special Rules" and "7.8 Custom kbuild commands"
are related because you must understand both of them when you write
custom rules.
Actually I do not understand the policy about what to go into
"3 The kbuild files" and what into "7 Architecture Makefile".
This commit reworks the custom rule explanation as follows:
- Merged "7.8 Custom kbuild commands" into "3.10 Special Rules".
- Reword "Special Rules" to "Custom Rules" for consistency.
- Update the example for kecho because the blackfin Makefile
does not exist any more.

Precisely speaking, the arch directory is specified by $(SRCARCH),
not $(ARCH).
In old days, $(ARCH) actually matched to the arch directory because
32-bit and 64-bit were supported as separate architectures.
Most architectures (except arm/arm64) were unified like follows:
arch/i386, arch/x86_64 -> arch/x86
arch/sh, arch/sh64 -> arch/sh
arch/sparc, arch/sparc64 -> arch/sparc
To not break the user interface, commit 6752ed90da ("Kbuild: allow
arch/xxx to use a different source path") introduced SRCARCH to point
to the arch directory, still allowing to pass in the former ARCH=i386
or ARCH=x86_64.
Update the documents for preciseness, and add the explanation of SRCARCH.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

This is a fairly big release cycle from the PWM framework's point of
view. There's a large patcheset here which converts drivers to use the
new devm_platform_ioremap_resource() helper and a bunch of minor fixes
to existing drivers. Some of the existing drivers also add support for
more hardware, such as Atmel SAMA 5D2 and Mediatek MT8183.
Finally there's a couple of new drivers for Intel Keem Bay and LGM SoCs
as well as the DesignWare PWM controller.

Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But
if the reset pin is not actually wired up, the driver exposes a
watchdog device that doesn't actually work.
Provide a standard binding that can be used to indicate that a given
RTC can perform a reset of the machine, similar to wakeup-source.

The binding should use "unevaluatedProperties" instead of
"additionalProperties", since it is a SPI device and may have
SPI-related Device Tree properties, for instance the "spi-max-frequency"
property that is present in the example.
