Sigma delta ADCs with a sequencer need to disable the previously enabled
channel when reading using ad_sigma_delta_single_conversion(). This was
done manually in drivers for devices with sequencers.
This patch implements handling of single channel disabling after a
single conversion.

Pull driver core and sysfs fixes from Greg KH:
"Here are three small changes for 6.10-rc4 that resolve reported
problems, and finally drop an unused api call. These are:
- removal of devm_device_add_groups(), all the callers of this are
finally gone after the 6.10-rc1 merge (changes came in through
different trees), so it's safe to remove.
- much reported sysfs build error fixed up for systems that did not
have sysfs enabled
- driver core sync issue fix for a many reported issue over the years
that no one really paid much attention to, until Dirk finally
tracked down the real issue and made the "obviously correct and
simple" fix for it.

IIO: 1st set of new device support, cleanups etc for 6.11
Lots of new device support and 3 entirely new drivers.
Early pull request this cycle to allow for clean picking up of fixes
that are dependencies for some queued patch sets.
Device support
==============
adi,ad3552r
- Add AD3541R and AD3551R - single output variants of already supported
DACs.
adi,ad7192
- Add support for ad7194 24-bit ADC with integrated PGA.
adi,ad7380
- New ADC driver built up in a number of steps. Supports
- 2 channel differential ADCs: AD7380, AD7381
- 4 channel differential ADCs: AD7380-4, AD7381-4
- 2 channel pseudo-differential ADCs: AD7383, AD7384
- 4 channel pseudo-differential ADCs: AD7383-4, AD7384-4
adi,adis16475
- Support ADS16501 variant - ID and some different scale factors from
parts already supported.
- Driver refactoring then enables support for 6 more IMUs:
- ADIS16575-[2,3]
- ADIS16576-[2,3]
- ADIS16577-[2,3]
adi,adsi16480
- Driver refactoring and feature additions leading to support for 6 more
IMUs - with new delta angle and delta velocity feature:
- ADIS16545-[1,2,3]
- ADIS16547-[1,2,3]
bosch,bmi160
- Support for the bmi120 IMU: ID only. Also relax ID checking to warn
only on mismatch allowing use of fallback compatibles for new devices.
sciosense,ens160
- New driver for this metal oxide multi-gas sensor for indoor
air quality monitoring.
sensortek,stk3110
- Support for stk3311a and stk3311s34 light sensor variants. Relax ID
checking to warn only on a mismatch allowing use of fallback compatibles
for new devices.
vishay,veml6040
- New driver for this RGBW light sensor. Note that whilst the register
interface is very different, the dt-binding similar enough that it is
shared with the existing vishay,veml6075 binding
x-powers,axp20x
- Add support for axp192, very similar to another supported PMIC ADC variant
but with a few more GPIO channels.
Dt-binding only
===============
ti,ads1015
- Add binding (no driver support yet) for ti,tla2021
New features
============
core
- Variable scan type support. We have papered over this for a long time
so good to finally resolve it.
Some devices will change their data output format (typically resolution)
dependent on settings such as oversampling. A new callback is added
to enable this. First used in the ad7380 driver.
- Harden the core against missing callback functions.
dt-binding:
- Add a single-channel property that can be used in per channel nodes
instead of reg to indicate which device channel. This is important
in devices with a mixture of differential and single ended channels
as reg already just acted as an index for the differential channels
making things inconsistent if it had more meaning for single ended
channels.
adi,ad7380
- Use spi_optimize_message() to reduce reading message setup overhead.
- Add oversampling support using the new core functionality to allow
a device support multiple scan types.
invense,icm42600
- Support for low-power accelerometer modes. When a given sampling
frequency is only supported at one power mode, use that. Otherwise
default to low power at the cost of some noise unless overridden
via a new sysfs attribute.
silicon-labs,si70720
- Add control of the heater.
Cleanups and minor fixes
========================
core
- Cleanup use of sizeof(struct xxxx) in favor of sizeof(*variable)
Makefile
- Resort the iio/adc/Makefile which has drifted away from alphabetical
order.
gts library
- Fix sorting of lists with a zero in the middle. Doesn't happen with
upstream drivers, but good to harden this code. Add a related unit test.
multiple drivers
- Add missing MODULE_DESCRIPTION()
- Drop some unused structure fields.
- Drop some entirely unused structure definitions.
- Stop pointless initialization of i2c_device_id::driver_data to 0 in drivers
where it isn't used.
- Use spi_get_device_match_data() to replace open-coded equivalent.
adi,ad3552r
- Fix dt gain parameter names to reflect what the driver does. Note
discussion in patch to justify fixing it in the binding not the
driver.
- Tidy up some naming.
adi,ad7192
- Use read_avail() callback to handle the low pass filter.
- Add an aincom supply for pseudo differential operation.
adi,ad7606
- Use iio_device_claim_direct_scoped() to simplify error paths.
adi,ad7944
- Drop an unused function parameter.
adi,adrf6780
- Drop unused header.
adi,ad9467
- Use a DMA safe buffer for SPI transfers.
- Stop using tabs to pad structure field names. It was creating a lot
of noise.
adi,axi-adc
- Prevent races between enable and disable calls.
- Ensure the DRP (dynamic reconfiguration port) is locked. Not used
in most real designs, but better safe than sorry.
- Limit build to COMPILE_TEST or platforms for which the IP exists.
adi,axi-dac
- Limit build to COMPILE_TEST or platforms for which the IP exists.
ams,iaq
- Use __packed instead of ___attribute__((__packed__))
bosch,bmp280
- White space cleanup.
- Use BME280 prefix for registers that do not exist on the BMP280.
- Add parameter names to callback function definitions.
- Rename measure function to better reflect what it does which is wait
for a measurement to happen.
- Drop a redundant error check.
- Improve error messages
- Make error checks consistent as if (ret)
- Use unsigned types for inherently unsigned data.
- Refactor reading functions to not rely on a hidden t_fine variable.
- Make use of cleanup.h
freescale,mma7660
- Add mount matrix support.
invense,icm42600
- Enable the regmap cache to reduce bus accesses.
amlogic,meson-saradc
- Add dt-binding support for power-domains.
ti,adc161s626
- Use iio_device_claim_direct_scoped() to simplify error handling.

Pull VFIO fixes from Alex Williamson:
"Fix long standing lockdep issue of using remap_pfn_range() from the
vfio-pci fault handler for mapping device MMIO. Commit ba168b52bf8e
("mm: use rwsem assertion macros for mmap_lock") now exposes this as a
warning forcing this to be addressed.
remap_pfn_range() was used here to efficiently map the entire vma, but
it really never should have been used in the fault handler and doesn't
handle concurrency, which introduced complex locking. We also needed
to track vmas mapping the device memory in order to zap those vmas
when the memory is disabled resulting in a vma list.
Instead of all that mess, setup an address space on the device fd
such that we can use unmap_mapping_range() for zapping to avoid the
tracking overhead and use the standard vmf_insert_pfn() to insert
mappings on fault.
For now we'll iterate the vma and opportunistically try to insert
mappings for the entire vma. This aligns with typical use cases, but
hopefully in the future we can drop the iterative approach and make
use of huge_fault instead, once vmf_insert_pfn{pud,pmd}() learn to
handle pfnmaps"

Pull io_uring fixes from Jens Axboe:
"Two fixes from Pavel headed to stable:

mutex
- Split cancel sequence flag into a separate variable, as it can get

|
|
Only the current owner of a request is allowed to write into req->flags.
Hence, the cancellation path should never touch it. Add a new field
instead of the flag, move it into the 3rd cache line because it should
always be initialised. poll_refs can move further as polling is an
involved process anyway.
It's a minimal patch, in the future we can and should find a better
place for it and remove now unused REQ_F_CANCEL_SEQ.

The user mapped intergity is copied back and unpinned by
bio_integrity_free which is a low-level routine. Do it via the submitter
rather than doing it in the low-level block layer code, to split the
submitter side from the consumer side of the bio.

We normally ksm_zero_pages++ in ksmd when page is merged with zero page,
but ksm_zero_pages-- is done from page tables side, where there is no any
accessing protection of ksm_zero_pages.
So we can read very exceptional value of ksm_zero_pages in rare cases,
such as -1, which is very confusing to users.
Fix it by changing to use atomic_long_t, and the same case with the
mm->ksm_zero_pages.

The mTHP swap related counters: 'anon_swpout' and 'anon_swpout_fallback'
are confusing with an 'anon_' prefix, since the shmem can swap out
non-anonymous pages. So drop the 'anon_' prefix to keep consistent with
the old swap counter names.
This is needed in 6.10-rcX to avoid having an inconsistent ABI out in the
field.

Currently, adis library allows configuration only for edge interrupts,
needed for data ready sampling.
This patch removes the restriction for level interrupts for devices
which have FIFO support.
Furthermore, in case of devices which have FIFO support,
devm_request_threaded_irq is used for interrupt allocation, to avoid
flooding the processor with the FIFO watermark level interrupt, which
is active until enough data has been read from the FIFO.

This adds new fields to the iio_channel structure to support multiple
scan types per channel. This is useful for devices that support multiple
resolution modes or other modes that require different data formats of
the raw data.
To make use of this, drivers need to implement the new callback
get_current_scan_type() to resolve the scan type for a given channel
based on the current state of the driver. There is a new scan_type_ext
field in the iio_channel structure that should be used to store the
scan types for any channel that has more than one. There is also a new
flag has_ext_scan_type that acts as a type discriminator for the
scan_type/ext_scan_type union. A union is used so that we don't grow
the size of the iio_channel structure and also makes it clear that
scan_type and ext_scan_type are mutually exclusive.
The buffer code is the only code in the IIO core code that is using the
scan_type field. This patch updates the buffer code to use the new
iio_channel_validate_scan_type() function to ensure it is returning the
correct scan type for the current state of the device when reading the
sysfs attributes. The buffer validation code is also update to validate
any additional scan types that are set in the scan_type_ext field. Part
of that code is refactored to a new function to avoid duplication.
Some userspace tools may need to be updated to re-read the scan type
after writing any other attribute. During testing, we noticed that we
had to restart iiod to get it to re-read the scan type after enabling
oversampling on the ad7380 driver.

While the experiment did reveal that there are additional places that are
missing the lock during secondary bus reset, one of the places that needs
to take cfg_access_lock (pci_bus_lock()) is not prepared for lockdep
annotation.
Specifically, pci_bus_lock() takes pci_dev_lock() recursively and is
currently dependent on the fact that the device_lock() is marked
lockdep_set_novalidate_class(&dev->mutex). Otherwise, without that
annotation, pci_bus_lock() would need to use something like a new
pci_dev_lock_nested() helper, a scheme to track a PCI device's depth in the
topology, and a hope that the depth of a PCI tree never exceeds the max
value for a lockdep subclass.
The alternative to ripping out the lockdep coverage would be to deploy a
dynamic lock key for every PCI device. Unfortunately, there is evidence
that increasing the number of keys that lockdep needs to track to be
per-PCI-device is prohibitively expensive for something like the
cfg_access_lock.
The main motivation for adding the annotation in the first place was to
catch unlocked secondary bus resets, not necessarily catch lock ordering
problems between cfg_access_lock and other locks. Solve that narrower
problem with follow-on patches, and just due to targeted revert for now.

After commit 8fea0c8fda30 ("usb: core: hcd: Convert from tasklet to BH
workqueue"), usb_giveback_urb_bh() runs in the BH workqueue with
interrupts enabled.
Thus, the remote coverage collection section in usb_giveback_urb_bh()->
__usb_hcd_giveback_urb() might be interrupted, and the interrupt handler
might invoke __usb_hcd_giveback_urb() again.
This breaks KCOV, as it does not support nested remote coverage collection
sections within the same context (neither in task nor in softirq).
Update kcov_remote_start/stop_usb_softirq() to disable interrupts for the
duration of the coverage collection section to avoid nested sections in
the softirq context (in addition to such in the task context, which are
already handled).

iommu_sva_bind_device() should return either a sva bond handle or an
ERR_PTR value in error cases. Existing drivers (idxd and uacce) only
check the return value with IS_ERR(). This could potentially lead to
a kernel NULL pointer dereference issue if the function returns NULL
instead of an error pointer.
In reality, this doesn't cause any problems because iommu_sva_bind_device()
only returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA.
In this case, iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will
return an error, and the device drivers won't call iommu_sva_bind_device()
at all.

With the vfio device fd tied to the address space of the pseudo fs
inode, we can use the mm to track all vmas that might be mmap'ing
device BARs, which removes our vma_list and all the complicated lock
ordering necessary to manually zap each related vma.
Note that we can no longer store the pfn in vm_pgoff if we want to use
unmap_mapping_range() to zap a selective portion of the device fd
corresponding to BAR mappings.
This also converts our mmap fault handler to use vmf_insert_pfn()
because we no longer have a vma_list to avoid the concurrency problem
with io_remap_pfn_range(). The goal is to eventually use the vm_ops
huge_fault handler to avoid the additional faulting overhead, but
vmf_insert_pfn_{pmd,pud}() need to learn about pfnmaps first.
Also, Jason notes that a race exists between unmap_mapping_range() and
the fops mmap callback if we were to call io_remap_pfn_range() to
populate the vma on mmap. Specifically, mmap_region() does call_mmap()
before it does vma_link_file() which gives a window where the vma is
populated but invisible to unmap_mapping_range().

A zoned device may have a last sequential write required zone that is
smaller than other zones. However, all tests to check if a zone write
plug write offset exceeds the zone capacity use the same capacity
value stored in the gendisk zone_capacity field. This is incorrect for a
zoned device with a last runt (smaller) zone.
Add the new field last_zone_capacity to struct gendisk to store the
capacity of the last zone of the device. blk_revalidate_seq_zone() and
blk_revalidate_conv_zone() are both modified to get this value when
disk_zone_is_last() returns true. Similarly to zone_capacity, the value
is first stored using the last_zone_capacity field of struct
blk_revalidate_zone_args. Once zone revalidation of all zones is done,
this is used to set the gendisk last_zone_capacity field.
The checks to determine if a zone is full or if a sector offset in a
zone exceeds the zone capacity in disk_should_remove_zone_wplug(),
disk_zone_wplug_abort_unaligned(), blk_zone_write_plug_init_request(),
and blk_zone_wplug_prepare_bio() are modified to use the new helper
functions disk_zone_is_full() and disk_zone_wplug_is_full().
disk_zone_is_full() uses the zone index to determine if the zone being
tested is the last one of the disk and uses the either the disk
zone_capacity or last_zone_capacity accordingly.

Since we have a dev_is_pnp() macro that utilises the address of the
pnp_bus_type variable, the users, which can be compiled as modules,
will fail to build. Convert the macro to be a function and export it
to the modules to prevent build breakage.

Rename and document TPM2_OA_TMPL, as originally requested in the patch
set review, but left unaddressed without any appropriate reasoning. The
new name is TPM2_OA_NULL_KEY, has a documentation and is local only to
tpm2-sessions.c.

With only single call site, this makes no sense (slipped out of the
radar during the review). Open code and document the action directly
to the site, to make it more readable.

We've added 15 non-merge commits during the last 7 day(s) which contain
a total of 18 files changed, 583 insertions(+), 55 deletions(-).
The main changes are:
1) Fix broken BPF multi-uprobe PID filtering logic which filtered by thread
while the promise was to filter by process, from Andrii Nakryiko.
2) Fix the recent influx of syzkaller reports to sockmap which triggered
a locking rule violation by performing a map_delete, from Jakub Sitnicki.
3) Fixes to netkit driver in particular on skb->pkt_type override upon pass
verdict, from Daniel Borkmann.
4) Fix an integer overflow in resolve_btfids which can wrongly trigger build
failures, from Friedrich Vock.
5) Follow-up fixes for ARC JIT reported by static analyzers,
from Shahab Vahedi.
