There are multiple open coded implementations for getting the parity of
a byte in the kernel, even using different approaches. Take the pretty
efficient version from SPD5118 driver and make it generally available by
putting it into the bitops header. As long as there is just one parity
calculation helper, the creation of a distinct 'parity.h' header was
discarded. Also, the usage of hweight8() for architectures having a
popcnt instruction is postponed until a use case within hot paths is
desired. The motivation for this patch is the frequent use of odd parity
in the I3C specification and to simplify drivers there.
Changes compared to the original SPD5118 version are the addition of
kernel documentation, switching the return type from bool to int, and
renaming the argument of the function.

Pull kvm fixes from Paolo Bonzini:
"The largest part here is for KVM/PPC, where a NULL pointer dereference
was introduced in the 6.13 merge window and is now fixed.
There's some "holiday-induced lateness", as the s390 submaintainer put
it, but otherwise things looks fine.

Pull IIO updaate from Jonathan:
IIO: 1st set of new device support, features and cleanup for 6.14
Fairly quiet cycle. Usual mix of new drivers, device support in
existing drivers, features and more general rework and cleanup.
There are a few late breaking or long standing but complex fixes
in here as well.
There is one expected merge conflict due to an upstream fix touching
neighboring code in ti-ads1119. The trivial resolution is the right one with
the result ending up as:
struct {
s16 sample;
aligned_s64 timestamp;
} scan;
New device support
==================
adi,ad4000
- Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688,
AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984,
AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series
but with lower sampling rates and no configuration registers.
Includes addition of timestamp channels.
adi,adis16480
- Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks
to existing driver and addition of tables.
kionix,kx022a
- Add support for KX134ACR-LBZ accelerometer that is similar to the
KX132ACR-LBZ but with a wider (+-64G) sensor range.
- Add support for KX134-1211 accelerometer that is similar to the
KX132-1211 but with a wider (+-16G) sensor range.
nxp,fxls8962af
- Add support for fxls8974cf and fxls8967af accelerometers, Both are
compatible with fxls8962af but with different device IDs which are used in
presence checks.
renesas,rzg2l
- Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors
precede this to allow for chip differences).
rohm,bd79704
- New driver for this 6 channel DAC.
st,mpu6050
- Support he IAM20380 which is effectively a cut down IAM20608 IMU with only
a gyroscope (no accelerometer).
st,stm-timmer-trigger
- Add support for ADC trigger use case for the STM32MP25 SOC. Do not support
the counter functionality in this driver as that is handled by the
counter subsystem.
ti,opt4060
- New driver for this RGBW color sensor.
Driver drop
===========
rohm,bu20008
- Drop as decision was made to not mass produce this light sensor after
Matti had done all the work to get a driver upstream.
Features
========
adi,ad_sigma_delta library + ad7124
- Allow for GPIO to check interrupt status, enabling this device on
more platforms that don't obey prior (non general) assumptions on
how the interrupt chips work.
- Allow variation in reset sequence length allowing chip specific
optimizations rather than always using worst case.
adi,ad7124
- Add temperature channel support.
adi,ad7173
- Add support calibration modes for this family of ADCs.
adi,adxl345
- Binding update to allow specification of which interrupt line is
connected (or none).
- Support interrupts and FIFO based data capture.
bosch,bme680
- Add regulators support. Note this required a new binding doc rather than
use of trivial-devices
- Runtime PM support.
microchip,pac1921
- Add ACPI support including _DSM for shunt value and label.
renesas,rzg2l
- Enable runtime autosuspend.
- Add suspend and resume support.
tyhx,hx9023s
- Add loading of a firmware file used to set defaults for some
configuration registers.
vishay,veml6030
- Support triggered buffers allowing efficient data capture at
higher speeds.
- Add regmap cache to reduce access to device.
Cleanup and minor fixes
=======================
cross-tree
- Another batch of conversions to devm_regulator_get_enable_read_voltage()
helper and related conversions to full devm that this enables.
- Various patches using guard() to allow early returns and simpler
code flow.
- Various conversions from s64 timestamp __aligned(8) to aligned_s64 type.
Includes a few cleanups where this unsigned and it should have been
signed.
- Fix up some missing types for drive-open-drain in dt-binding docs.
core
- Add missing documentation for iio_dmaengine_buffer_setup_ext()
- Add check that all buffers passed to iio_read_channel_ext_info()
and iio_read_channel_label() are page sized and page aligned.
Done this way because the callbacks are almost always only used
to fill sysfs attributes. The check covers the tiny percentage
of cases where use is made of this data in a consumer driver.
- Mark scan_timestamp memory of struct iio_dev private ensuring no
drivers change the value which belongs to the IIO core.
documentation
- Various missing ABI docs added.
- ABI docs made to use Y consistently as the wildcard for channel
number.
- Combine duplicate in_currentY_raw entries in ABI docs.
iio-mux
- Fix alignment of buffers passed to iio_channel_read_ext_info().
adi,ad_sigma_delta library
- Respect keep_cs_asserted flag in read path.
- Close a race condition around irq enabling and disabling.
- Use explicit unsigned int in place of unsigned.
adi,ad6695
- Move dt-binding header under adc sub-directory and fix include path in dt
example.
adi,ad7124
- Check number of channels in DT doesn't exceed what the driver can handle.
- Check input specified in DT are possible.
- Improved error reporting during probe.
adi,ad7173
- Drop unused structure element.
adi,ad7293
- Ensure power is turned on before resetting.
adi,adxl345
- Some documentation simplification and parameter renames.
- Add a function than unifies handling of power up and power down.
- Add defines to have a complete set of registers defined.
- Add missing \n to end of error messages.
amlogic,meson_saradc
- Simplify handling of the REG11 register access.
awinic,aw96104
- Constify iio_info structure.
bosch,bmp085
- Add to dt-binding to indicate devices support SPI.
bosch,bmp280
- Use sizeof() to replace a somewhat magic 2.
- Rename sleep related variables so the unit is included and use
fsleep() to replace usleep_range() calls.
bosch,bno055
- Constify struct bin_attribute
capella,cm3232
- Reset device before checking hardware ID inline with suggested flow
from datasheet.
diolan,dln2
- Simplify zeroing of structure used to gather up data by just
clearing the whole thing before writing rather than trying to
clear out he padding after write.
freescale,vf610
- Use devm_ and dev_error_probe() to simplify code and allow dropping
of explicit remove() callback.
invensense,timestamp library
- Use a cast to remove possibility of integer overflow.
kionix,kx022a
- Increase reset delay a little.
maxim,max1363
- Use a buffer of sufficient size in iio_priv() rather than allocating
variable sized buffer at use time.
microchip,mcp4725
- Replace of_property_read_bool() with of_property_present() for
detecting presence of regulator which is obviously not a bool.
nxp,fxls8962af
- Add wakeup-source property to the dt binding to allow these sensors
to wake the system up from suspend.
- Enable finer grained build when not all bus types need to be supported.
renesas,rzg2l
- Use dev_err_probe(), improving handling of probe errors and simplifying
code.
- Convert to devm_ based cleanup.
- Remove unnecessary runtime PM complexity as clocks are managed through
PM domains.
- Switch pm_ptr() removing need for __maybe_unused markings.
- use read_poll_timeout() to replace open coded equivalent.
samsung, ssp_sensors
- Simplify code by always providing timestamp whether or not it
is enabled.
st,lsm6dsx
- Avoid need to include linux/i3c/master by using i3cdev_to_dev() to
get to the contained struct device.
st,stm32-timer-trigger
- Check for clk_enable() fails.
vishay,veml6030
- Use new gts-helper functions and fix the _scale attribute to take into
account changes in gain and integration time.
Various other typo fixes in variable names + documentation and help text.
A few whitespace cleanup patches.

So far we notify the sequencer client and port changes upon UMP FB
changes, but those aren't really corresponding to the UMP updates.
e.g. when a FB info gets updated, it's not notified but done only when
some of sequencer port attribute is changed. This is no ideal
behavior.
This patch adds the two new sequencer event types for notifying the
UMP EP and FB changes via the announce port. The new event takes
snd_seq_ev_ump_notify type data, which is compatible with
snd_seq_addr (where the port number is replaced with the block
number).
The events are sent when the EP and FB info gets updated explicitly
via ioctl, or the backend UMP receives the corresponding UMP
messages.
The sequencer protocol version is bumped to 1.0.5 along with it.

The UMP legacy rawmidi may turn on/off the substream dynamically
depending on the UMP Function Block information. So far, there was no
direct way to know whether the substream is disabled (inactive) or
not; at most one can take a look at the substream name string or try
to open and get -ENODEV.
This patch extends the rawmidi info ioctl to show the current inactive
state of the given substream. When the selected substream is
inactive, info flags field contains the new bit flag
SNDRV_RAWMIDI_INFO_STREAM_INACTIVE.

The UMP legacy rawmidi is derived from the UMP rawmidi, but currently
there is no way to know which device is involved in other side.
This patch extends the rawmidi info ioctl to show the tied device
number. As default it stores -1, indicating that no tied device.

Move kvfree_rcu() functionality to the slab_common.c file.
The reason to have kvfree_rcu() functionality as part of SLAB is that
there is a clear trend and need of closer integration. One of the recent
example is creating a barrier function for SLAB caches.
Another reason is to prevent of having several implementations of RCU
machinery for reclaiming objects after a GP. As future steps, it can be
more integrated(easier) with SLAB internals.

The NVMe specifications mandate support for the host identifier
set_features for controllers that also supports reservations. Satisfy
this requirement by implementing handling of the NVME_FEAT_HOST_ID
feature for the nvme_set_features command. This implementation is for
now effective only for PCI target controllers. For other controller
types, the set features command is failed with a NVME_SC_CMD_SEQ_ERROR
status as before.
As noted in the code, 128 bits host identifiers are supported since the
NVMe base specifications version 2.1 indicate in section 5.1.25.1.28.1
that "The controller may support a 64-bit Host Identifier...".
The RHII (Reservations and Host Identifier Interaction) bit of the
controller attribute (ctratt) field of the identify controller data is
also set to indicate that a host ID of "0" is supported but that the
host ID must be a non-zero value to use reservations.

type becoming the new default, nvmet_referral_make() and
nvmet_ports_make() are modified to initialize a port discovery address
transport type field (disc_addr.trtype) to NVMF_TRTYPE_MAX.
Any port using this transport type is also skipped and not reported in
the discovery log page (nvmet_execute_disc_get_log_page()).
The helper function nvmet_is_pci_ctrl() is also introduced to check if
a target controller uses the PCI transport.

Move the declaration of all helper functions converting NVMe command
opcodes and status codes into strings from drivers/nvme/host/nvme.h
into include/linux/nvme.h, together with the commands definitions.
This allows NVMe target drivers to call these functions without having

Commit 86e25f40aa1e ("net: napi: Add napi_config") moved napi->napi_id
assignment to a later point in time (napi_hash_add_with_id). This breaks
__xdp_rxq_info_reg which copies napi_id at an earlier time and now
stores 0 napi_id. It also makes sk_mark_napi_id_once_xdp and
__sk_mark_napi_id_once useless because they now work against 0 napi_id.
Since sk_busy_loop requires valid napi_id to busy-poll on, there is no way
to busy-poll AF_XDP sockets anymore.
Bring back the ability to busy-poll on XSK by resolving socket's napi_id
at bind time. This relies on relatively recent netif_queue_set_napi,
but (assume) at this point most popular drivers should have been converted.
This also removes per-tx/rx cycles which used to check and/or set
the napi_id value.
Confirmed by running a busy-polling AF_XDP socket
(github.com/fomichev/xskrtt) on mlx5 and looking at BusyPollRxPackets
from /proc/net/netstat.

The snd_hdac_adsp_xxx() wrap snd_hdac_reg_xxx() helpers to simplify
register access for AudioDSP drivers e.g.: the avs-driver. Byte- and
word-variants of said helps do not expand to bare readx/writex()
operations but functions instead and, due to pointer type
incompatibility, cause compilation to fail.
As the macros are utilized by the avs-driver alone, relocate the code
introduced with commit c19bd02e9029 ("ALSA: hda: Add helper macros for
DSP capable devices") into the avs/ directory and update it to operate
on 'adev' i.e.: the avs-driver-context directly to fix the issue.

With gendwarfksyms, we need each TU where the EXPORT_SYMBOL() macro
is used to also contain DWARF type information for the symbols it
exports. However, as a TU can also export external symbols and
compilers may choose not to emit debugging information for symbols not
defined in the current TU, the missing types will result in missing
symbol versions. Stand-alone assembly code also doesn't contain type
information for exported symbols, so we need to compile a temporary
object file with asm-prototypes.h instead, and similarly need to
ensure the DWARF in the temporary object file contains the necessary
types.
To always emit type information for external exports, add explicit
__gendwarfksyms_ptr_<symbol> references to them in EXPORT_SYMBOL().
gendwarfksyms will use the type information for __gendwarfksyms_ptr_*
if needed. Discard the pointers from the final binary to avoid further
bloat.

In the SPI-NAND layer, we currently make list of operation variants from
the fastest one to the slowest and there is a bit of logic in the core
to go over them and pick the first one that is supported by the
controller, ie. the fastest one among the supported ops.
This kind of logic only works if all operations run at the same
frequency, but as soon as we introduce per operation max frequencies it
is not longer as obvious which operation will be faster, especially
since it also depends on the PCB/controller frequency limitation.
One way to make this choice more clever is to go over all the
variants and for each of them derive an indicator which will help derive
the theoretical best. In this case, we derive a theoretical duration for
the entire operation and we take the smallest one.
Add a helper that parses the spi-mem operation and returns this value.

Implement the necessary callbacks to switch the 8250 console driver
to perform as an nbcon console.
Add implementations for the nbcon console callbacks:
->write_atomic()
->write_thread()
->device_lock()
->device_unlock()
and add CON_NBCON to the initial @flags.
All register access in the callbacks are within unsafe sections.
The ->write_atomic() and ->write_thread() callbacks allow safe
handover/takeover per byte and add a preceding newline if they
take over from another context mid-line.
For the ->write_atomic() callback, a new irq_work is used to defer
modem control since it may be called from a context that does not
allow waking up tasks.
Note: A new __serial8250_clear_IER() is introduced for direct
clearing of UART_IER. This will allow to restore the lockdep
check to serial8250_clear_IER() in a follow-up commit.

For RS485 mode, if SER_RS485_RX_DURING_TX is not available, the
console ->write() callback needs to enable/disable Tx. It does
this by calling the ->rs485_start_tx() and ->rs485_stop_tx()
callbacks. However, some of these callbacks also disable/enable
interrupts and makes power management calls. This causes 2
problems for console writing:
1. A console write can occur in contexts that are illegal for
pm_runtime_*(). It is not even necessary for console writing
to use pm_runtime_*() because a console already does this in
serial8250_console_setup() and serial8250_console_exit().
2. The console ->write() callback already handles
disabling/enabling the interrupts by properly restoring the
previous IER value.
Add an argument @toggle_ier to the ->rs485_start_tx() and
->rs485_stop_tx() callbacks to specify if they may disable/enable
receive interrupts while using pm_runtime_*(). Console writing
will not allow the toggling.
For all call sites other than console writing there is no
functional change.

devm_remove_action() warns if the action to remove does not exist
(anymore).
The Rust devres abstraction, however, has a use-case to call
devm_remove_action() at a point where it can't be guaranteed that the
corresponding action hasn't been released yet.
In particular, an instance of `Devres<T>` may be dropped after the
action has been released. So far, `Devres<T>` worked around this by
keeping the inner type alive.
Hence, add devm_remove_action_nowarn(), which returns an error code if
the action has been removed already.
A subsequent patch uses devm_remove_action_nowarn() to remove the action
when `Devres<T>` is dropped.

There are several for_each APIs which has parameter with type below:
int (*fn)(struct device *dev, void *data)
They iterate over various device lists and call @fn() for each device
with caller provided data @*data, and they usually need to modify @*data.
Give the type an dedicated typedef with advantages shown below:
typedef int (*device_iter_t)(struct device *dev, void *data)
- Shorter API declarations and definitions
- Prevent further for_each APIs from using bad parameter type
So introduce device_iter_t and apply it to various existing APIs below:
bus_for_each_dev()
(class|driver)_for_each_device()
device_for_each_child(_reverse|_reverse_from)().

- Types for both @data and @fn are not consistent with all other

Commit 71810db27c1c ("modversions: treat symbol CRCs as 32 bit
quantities") changed the CRC fields to s32 because the __kcrctab and
__kcrctab_gpl sections contained relative references to the actual
CRC values stored in the .rodata section when CONFIG_MODULE_REL_CRCS=y.
Commit 7b4537199a4a ("kbuild: link symbol CRCs at final link, removing
CONFIG_MODULE_REL_CRCS") removed this complexity. Now, the __kcrctab
and __kcrctab_gpl sections directly contain the CRC values in all cases.
The genksyms tool outputs unsigned 32-bit CRC values, so u32 is preferred
over s32.
No functional changes are intended.
Regardless of this change, the CRC value is assigned to the u32 variable
'crcval' before the comparison, as seen in kernel/module/version.c:
crcval = *crc;
It was previously mandatory (but now optional) in order to avoid sign
extension because the following line previously compared 'unsigned long'
and 's32':
if (versions[i].crc == crcval)
return 1;
versions[i].crc is still 'unsigned long' for backward compatibility.
