The existing pmu documentation describes the limitation of perf
infrastructure in RISC-V ISA and limited feature set of perf in RISC-V.
However, SBI PMU extension and sscofpmf extension(ISA extension) allows to
implement most of the required features of perf. Remove the old
documentation which is not accurate anymore.

Pull random number generator updates from Jason Donenfeld:
"There have been a few important changes to the RNG's crypto, but the
intent for 5.18 has been to shore up the existing design as much as
possible with modern cryptographic functions and proven constructions,
rather than actually changing up anything fundamental to the RNG's
design.
So it's still the same old RNG at its core as before: it still counts
entropy bits, and collects from the various sources with the same
heuristics as before, and so forth. However, the cryptographic
algorithms that transform that entropic data into safe random numbers
have been modernized.
Just as important, if not more, is that the code has been cleaned up
and re-documented. As one of the first drivers in Linux, going back to
1.3.30, its general style and organization was showing its age and
becoming both a maintenance burden and an auditability impediment.
Hopefully this provides a more solid foundation to build on for the
future. I encourage you to open up the file in full, and maybe you'll
remark, "oh, that's what it's doing," and enjoy reading it. That, at
least, is the eventual goal, which this pull begins working toward.
Here's a summary of the various patches in this pull:
- /dev/urandom and /dev/random now do the same thing, per the patch
we discussed on the list. I think this is worth trying out. If it
does appear problematic, I've made sure to keep it standalone and
revertible without any conflicts.
- Fixes and cleanups for numerous integer type problems, locking
issues, and general code quality concerns.
- The input pool's LFSR has been replaced with a cryptographically
secure hash function, which has security and performance benefits
alike, and consequently allows us to count entropy bits linearly.
- The pre-init injection now uses a real hash function too, instead
of an LFSR or vanilla xor.
- The interrupt handler's fast_mix() function now uses one round of
SipHash, rather than the fake crypto that was there before.
- All additions of RDRAND and RDSEED now go through the input pool's
hash function, in part to mitigate ridiculous hypothetical CPU
backdoors, but more so to have a consistent interface for ingesting
entropy that's easy to analyze, making everything happen one way,
instead of a potpourri of different ways.
- The crng now works on per-cpu data, while also being in accordance
with the actual "fast key erasure RNG" design. This allows us to
fix several boot-time race complications associated with the prior
dynamically allocated model, eliminates much locking, and makes our
backtrack protection more robust.
- Batched entropy now erases doled out values so that it's backtrack
resistant.
- Working closely with Sebastian, the interrupt handler no longer
needs to take any locks at all, as we punt the
synchronized/expensive operations to a workqueue. This is
especially nice for PREEMPT_RT, where taking spinlocks in irq
context is problematic. It also makes the handler faster for the
rest of us.
- Also working with Sebastian, we now do the right thing on CPU
hotplug, so that we don't use stale entropy or fail to accumulate
new entropy when CPUs come back online.
- We handle virtual machines that fork / clone / snapshot, using the
"vmgenid" ACPI specification for retrieving a unique new RNG seed,
which we can use to also make WireGuard (and in the future, other
things) safe across VM forks.
- Around boot time, we now try to reseed more often if enough entropy
is available, before settling on the usual 5 minute schedule.
- Last, but certainly not least, the documentation in the file has
been updated considerably"

Pull ACPI updates from Rafael Wysocki:
"From the new functionality perspective, the most significant items
here are the new driver for the 'ARM Generic Diagnostic Dump and
Reset' device, the extension of fine grain fan control in the ACPI fan
driver, and the change making it possible to use CPPC information to
obtain CPU capacity.
There are also a few new quirks, a bunch of fixes, including the
platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.
Specifics:
- Use uintptr_t and offsetof() in the ACPICA code to avoid compiler
warnings regarding NULL pointer arithmetic (Rafael Wysocki).
- Fix possible NULL pointer dereference in acpi_ns_walk_namespace()
when passed "acpi=off" in the command line (Rafael Wysocki).
- Fix and clean up acpi_os_read/write_port() (Rafael Wysocki).
- Introduce acpi_bus_for_each_dev() and use it for walking all ACPI
device objects in the Type C code (Rafael Wysocki).
- Fix the _OSC platform capabilities negotioation and prevent CPPC
from being used if the platform firmware indicates that it not
supported via _OSC (Rafael Wysocki).
- Use ida_alloc() instead of ida_simple_get() for ACPI enumeration of
devices (Rafael Wysocki).
- Add AGDI and CEDT to the list of known ACPI table signatures (Ilkka
Koskinen, Robert Kiraly).
- Add power management debug messages related to suspend-to-idle in
two places (Rafael Wysocki).
- Fix __acpi_node_get_property_reference() return value and clean up
that function (Andy Shevchenko, Sakari Ailus).
- Fix return value of the __setup handler in the ACPI PM timer clock
source driver (Randy Dunlap).
- Clean up double words in two comments (Tom Rix).
- Add "skip i2c clients" quirks for Lenovo Yoga Tablet 1050F/L and
Nextbook Ares 8 (Hans de Goede).
- Clean up frequency invariance handling on x86 in the ACPI CPPC
library (Huang Rui).
- Work around broken XSDT on the Advantech DAC-BJ01 board (Mark
Cilissen).
- Make wakeup events checks in the ACPI EC driver more
straightforward and clean up acpi_ec_submit_event() (Rafael
Wysocki).
- Make it possible to obtain the CPU capacity with the help of CPPC
information (Ionela Voinescu).
- Improve fine grained fan control in the ACPI fan driver and
document it (Srinivas Pandruvada).
- Add device HID and quirk for Microsoft Surface Go 3 to the ACPI
battery driver (Maximilian Luz).
- Make the ACPI driver for Intel SoCs (LPSS) let the SPI driver know
the exact type of the controller (Andy Shevchenko).
- Force native backlight mode on Clevo NL5xRU and NL5xNU (Werner
Sembach).
- Fix return value of __setup handlers in the APEI code (Randy
Dunlap).
- Add Arm Generic Diagnostic Dump and Reset device driver (Ilkka
Koskinen).
- Limit printable size of BERT table data (Darren Hart).
- Fix up HEST and GHES initialization (Shuai Xue).
- Update the ACPI device enumeration documentation and unify the ASL
style in GPIO-related examples (Andy Shevchenko)"

Move compound_pincount from the third page to the second page, which
means it's available for all compound pages. That lets us delete
hpage_pincount_available().
On 32-bit systems, there isn't enough space for both compound_pincount
and compound_nr in the second page (it would collide with page->private,
which is in use for pages in the swap cache), so revert the optimisation
of storing both compound_order and compound_nr on 32-bit systems.

KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not
advertise the set of quirks which may be disabled to userspace, so it is
impossible to predict the behavior of KVM. Worse yet,
KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning
it fails to reject attempts to set invalid quirk bits.
The only valid workaround for the quirky quirks API is to add a new CAP.
Actually advertise the set of quirks that can be disabled to userspace
so it can predict KVM's behavior. Reject values for cap->args[0] that
contain invalid bits.
Finally, add documentation for the new capability and describe the
existing quirks.

'virtio,mmio' devices are always coherent within a guest. As Arm DTs
are default non-coherent, the 'dma-coherent' property needs to be set on
the virtio device to mark them as such. This aligns with the QEMU 'virt'

The CSR GSD4t is a CSR product using the SiRFstarIV core, and
the CSR CSRG05TA03-ICJE-R is a CSR product using the SiRFstarV

These chips have a SRESETN line that can be pulled low to hard
reset the chip and in some designs this is connected to a GPIO,
so add this as an optional property.
Update the example with a reset line so users see that it need
to be tagged as active low.

In particular, there is release candidate phase between ACKing patches
and new stable release. Also, in case of failed submissions (fail to
apply to stable tree), manual backport (Option 3) have to be submitted
instead.
Update the release cycle documentation on stable-kernel-rules.rst to

Most NVMEM providers have cells at hardcoded addresses however there are
some exceptions. Some devices store cells layout in internal structs
using custom formats.
It's important to allow NVMEM consumers to still reference such NVMEM
cells. Making "reg" optional allows defining NVMEM cells by their names
only and using them with phandles.

Add a compatible for the UART on the ARTPEC-8 SoC. This hardware block
is closely related to the variants used on the Exynos chips. The
register layout is identical to Exynos850 et al but the fifo size is
different (64 bytes in each direction for all instances).

This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.

It should be familiar and beneficial to expose devlink instance
lock to the drivers. This way drivers can block devlink from
calling them during critical sections without breakneck locking.
Add port helpers, port splitting callbacks will be the first
target.
Use 'devl_' prefix for "explicitly locked" API. Initial RFC used
'__devlink' but that's too much typing.
devl_lock_is_held() is not defined without lockdep, which is
the same behavior as lockdep_is_held() itself.

This binding is heavily based on the one for NPCM7xx, because the
hardware is similar. There are some notable differences, however:
- The addresses of GPIO banks are not physical addresses but simple
indices (0 to 7), because the GPIO registers are not laid out in
convenient blocks.
- Pinmux settings can explicitly specify that the GPIO mode is used.
Certain pins support blink patterns in hardware. This is currently not
modelled in the DT binding.

During a patch discussion, Linus brought up the option of changing
the C standard version from gnu89 to gnu99, which allows using variable
declaration inside of a for() loop. While the C99, C11 and later standards
introduce many other features, most of these are already available in
gnu89 as GNU extensions as well.
An earlier attempt to do this when gcc-5 started defaulting to
-std=gnu11 failed because at the time that caused warnings about
designated initializers with older compilers. Now that gcc-5.1 is
the minimum compiler version used for building kernels, that is no
longer a concern. Similarly, the behavior of 'inline' functions changes
between gnu89 using gnu_inline behavior and gnu11 using standard c99+
behavior, but this was taken care of by defining 'inline' to include
__attribute__((gnu_inline)) in order to allow building with clang a
while ago.
Nathan Chancellor reported a new -Wdeclaration-after-statement
warning that appears in a system header on arm, this still needs a
workaround.
The differences between gnu99, gnu11, gnu1x and gnu17 are fairly
minimal and mainly impact warnings at the -Wpedantic level that the
kernel never enables. Between these, gnu11 is the newest version
that is supported by all supported compiler versions, though it is
only the default on gcc-5, while all other supported versions of
gcc or clang default to gnu1x/gnu17.

Block Aperture Window support was an attempt to layer an error model
over PMEM for platforms that did not support machine-check-recovery.
However, it was abandoned before it ever shipped, and only ever existed
in the ACPI specification. Meanwhile Linux has carried a large pile of
dead code for non-shipping infrastructure. For years it has been off to
the side out of the way, but now CXL and recent directions with DAX
support have the potential to collide with this code.
In preparation for adding discontiguous namespace support, a
pre-requisite for the nvdimm subsystem to replace device-mapper for
striping + concatenation use cases, delete BLK aperture support.
On the obscure chance that some hardware vendor shipped support for this
mode, note that the driver will still keep BLK space reserved in the
label area. So an end user in this case would still have the opportunity
to report the regression to get BLK-mode support restored without
risking the data they have on that device.

Switch the DT validation to use DTB files directly instead of a DTS to
YAML conversion.
The original motivation for supporting validation on DTB files was to
enable running validation on a running system (e.g. 'dt-validate
/sys/firmware/fdt') or other cases where the original source DTS is not
available.
The YAML format was not without issues. Using DTBs with the schema type
information solves some of those problems. The YAML format relies on the
DTS source level information including bracketing of properties, size
directives, and phandle tags all of which are lost in a DTB file. While
standardizing the bracketing is a good thing, it does cause a lot of
extra warnings and churn to fix them.
Another issue has been signed types are not validated correctly as sign
information is not propagated to YAML. Using the schema type information
allows for proper handling of signed types. YAML also can't represent
the full range of 64-bit integers as numbers are stored as floats by
most/all parsers.
The DTB validation works by decoding property values using the type
information in the schemas themselves. The main corner case this does
not work for is matrix types where neither dimension is fixed. For
now, checking the dimensions in these cases are skipped.

The Allwinner F1C100 series contains two MMC controller blocks. From
comparing the data sheets, they seem to be compatible with the one used
in the Allwinner A20: the register layout is the same, and they use the
same separate sample and output clocks design.
The only difference is the missing reset line in the A20 version, but
both the binding and the Linux driver make this optional, so it's still
a fit.
Add the new SoC specific name and require it to be paired with the A20
fallback name, as this is all the driver needs to care about.

In preparation for supporting validation of DTB files, the full
processed schema will always be needed in order to extract type
information from it. Therefore, the processed schema containing only
what DT_SCHEMA_FILES specifies won't work. Instead, dt-validate has
gained an option, -l or --limit, to specify which schema(s) to use for
validation.
As the command line option is new, we the minimum dtschema version must be
updated.

This new incompatible revision of the AIC peripheral introduces
multi-die support. This binding is based on apple,aic, but
changes interrupt-cells to add a new die argument.
Also adds a second reg entry to specify the offset of the event
register. Inexplicably, the capability registers allow us to compute
other register offsets, but not this one. This allows us to keep
forward-compatibility with future SoCs that will likely implement
different die counts, thus shifting the event register. Apple also
specify the offset explicitly in their device tree...

Marc Kleine-Budde says:
====================
pull-request: can-next 2022-03-10
The first 3 patches are by Oliver Hartkopp, target the CAN ISOTP
protocol and update the CAN frame sending behavior, and increases the
max PDU size to 64 kByte.
The next 2 patches are also by Oliver Hartkopp and update the virtual
VXCAN driver so that CAN frames send into the peer name space show up
as RX'ed CAN frames.
Vincent Mailhol contributes a patch for the etas_es58x driver to fix a
false positive dereference uninitialized variable warning.
2 patches by Ulrich Hecht add r8a779a0 SoC support to the rcar_canfd
driver.
The remaining 21 patches target the gs_usb driver and are by Peter
Fink, Ben Evans, Eric Evenchick and me. This series cleans up the
gs-usb driver, documents some bits of the USB ABI used by the widely
used open source firmware candleLight, adds support for up to 3 CAN
interfaces per USB device, adds CAN-FD support, adds quirks for some
hardware and software workarounds and finally adds support for 2 new
devices.

Back when tcp_tso_autosize() and TCP pacing were introduced,
our focus was really to reduce burst sizes for long distance
flows.
The simple heuristic of using sk_pacing_rate/1024 has worked
well, but can lead to too small packets for hosts in the same
rack/cluster, when thousands of flows compete for the bottleneck.
Neal Cardwell had the idea of making the TSO burst size
a function of both sk_pacing_rate and tcp_min_rtt()
Indeed, for local flows, sending bigger bursts is better
to reduce cpu costs, as occasional losses can be repaired
quite fast.
This patch is based on Neal Cardwell implementation
done more than two years ago.
bbr is adjusting max_pacing_rate based on measured bandwidth,
while cubic would over estimate max_pacing_rate.
/proc/sys/net/ipv4/tcp_tso_rtt_log can be used to tune or disable
this new feature, in logarithmic steps.
Tested:
100Gbit NIC, two hosts in the same rack, 4K MTU.
600 flows rate-limited to 20000000 bytes per second.
Before patch: (TSO sizes would be limited to 20000000/1024/4096 -> 4 segments per TSO)

The VGA arbiter is really PCI-specific and doesn't depend on any GPU
things. Move it to the PCI subsystem.
Note that misc_init() must be called before vga_arb_device_init(). These
are both subsys_initcalls, so this ordering depends on the link order,
which is determined by drivers/Makefile:
obj-y += pci/
obj-y += char/ <-- misc_init()
obj-y += gpu/ <-- vga_arb_device_init() (before this commit)
The drivers/pci/ subsys_initcalls are called *before* misc_init(), so
convert vga_arb_device_init() to subsys_initcall_sync(), which is called
after *all* subsys_initcalls.

As pointed out by Evgenii Stepanov one potential issue with the new ABI for
enabling asymmetric is that if there are multiple places where MTE is
configured in a process, some of which were compiled with the old prctl.h
and some of which were compiled with the new prctl.h, there may be problems
keeping track of which MTE modes are requested. For example some code may
disable only sync and async modes leaving asymmetric mode enabled when it
intended to fully disable MTE.
In order to avoid such mishaps remove asymmetric mode from the prctl(),
instead implicitly allowing it if both sync and async modes are requested.
This should not disrupt userspace since a process requesting both may
already see a mix of sync and async modes due to differing defaults between
CPUs or changes in default while the process is running but it does mean
that userspace is unable to explicitly request asymmetric mode without
changing the system default for CPUs.

Revert DPI support from binding.
DPI support relies on the bus-type enum which does not yet support
Mipi DPI, since no v4l2_fwnode_bus_type has been defined for this
bus type.
When DPI for anx7625 was initially added, it assumed that
V4L2_FWNODE_BUS_TYPE_PARALLEL was the correct bus type for
representing DPI, which it is not.
In order to prevent adding this mis-usage to the ABI, let's revert
the support.

This rewrites the former text based AB8500 bindings in YAML.
When the AB8500 bindings were first written (in 2012) we
were not strict on some things and node names were definitely
not standardized.
This patch uses standard node names to most of the subnodes
on the AB8500 and is accompanied by another patch fixing
all the DTS files to conform to this.
The bindings are not as perfect as newly written bindings
would be, it is a best effort to deal with the legacy.
