It was a mistake to prefer polling based mode when setting a performance
level for a domain. Let's instead rely on the protocol to decide what is
best and thus avoid polling when possible.

Commit 6bbd42e2df8f ("mmu_notifiers: call invalidate_range() when
invalidating TLBs") moved the secondary TLB invalidations into the TLB
invalidation functions to ensure that all secondary TLB invalidations
happen at the same time as the CPU invalidation and added a flush-all
type of secondary TLB invalidation for the batched mode, where a range
of [0, -1UL) is used to indicates that the range extends to the end of
the address space.
However, using an end address of -1UL caused an overflow in the Intel
IOMMU driver, where the end address was rounded up to the next page.
As a result, both the IOTLB and device ATC were not invalidated correctly.
Add a flush all helper function and call it when the invalidation range
is from 0 to -1UL, ensuring that the entire caches are invalidated
correctly.

The VT-d spec requires (10.4.4 Global Command Register, TE field) that:
Hardware implementations supporting DMA draining must drain any in-flight
DMA read/write requests queued within the Root-Complex before switching
address translation on or off and reflecting the status of the command
through the TES field in the Global Status register.
Unfortunately, some integrated graphic devices fail to do so after some
kind of power state transition. As the result, the system might stuck in
iommu_disable_translation(), waiting for the completion of TE transition.
Add MTL to the quirk list for those devices and skips TE disabling if the
qurik hits.

The enforce_cache_coherency callback ensures DMA cache coherency for
devices attached to the domain.
Intel IOMMU supports enforced DMA cache coherency when the Snoop
Control bit in the IOMMU's extended capability register is set.
Supporting it differs between legacy and scalable modes.
In legacy mode, it's supported page-level by setting the SNP field
in second-stage page-table entries. In scalable mode, it's supported
in PASID-table granularity by setting the PGSNP field in PASID-table
entries.
In legacy mode, mappings before attaching to a device have SNP
fields cleared, while mappings after the callback have them set.
This means partial DMAs are cache coherent while others are not.
One possible fix is replaying mappings and flipping SNP bits when
attaching a domain to a device. But this seems to be over-engineered,
given that all real use cases just attach an empty domain to a device.
To meet practical needs while reducing mode differences, only support
enforce_cache_coherency on a domain without mappings if SNP field is
used.

It turns out there are more subtle races beyond just the main part of
__iommu_probe_device() itself running in parallel - the dev_iommu_free()
on the way out of an unsuccessful probe can still manage to trip up
concurrent accesses to a device's fwspec. Thus, extend the scope of
iommu_probe_device_lock() to also serialise fwspec creation and initial
retrieval.

Most of the calling code now has error handling that can carry an error
code further up the call chain. Keep the exported interface
iommu_domain_alloc() returning NULL and reflow the internal code to use
ERR_PTR not NULL for domain allocation failure.
Optionally allow drivers to return ERR_PTR from any of the alloc ops. Many
of the new ops (user, sva, etc) already return ERR_PTR, so having two
rules is confusing and hard on drivers. This fixes a bug in DART that was
returning ERR_PTR.

Commit ee708e6baacd ("iio: buffer: introduce support for attaching more
IIO buffers") introduced support for multiple buffers per indio_dev but
left indio_dev->buffer for a few legacy use cases.
In the case of the triggered buffer, iio_triggered_buffer_cleanup()
still assumes that indio_dev->buffer points to the buffer allocated by
iio_triggered_buffer_setup_ext(). However, since
iio_triggered_buffer_setup_ext() now calls iio_device_attach_buffer()
to attach the buffer, indio_dev->buffer will only point to the buffer
allocated by iio_device_attach_buffer() if it the first buffer attached.
This adds a check to make sure that no other buffer has been attached
yet to ensure that indio_dev->buffer will be assigned when
iio_device_attach_buffer() is called.
As per discussion in the review thread, we may want to deal with multiple
triggers per device, but this is a fix for the issue in the meantime and
any such support would be unlikely to be suitable for a backport.

The blamed commit added support for Rx copybreak. This meant that for
certain frame sizes, a new skb was allocated and the initial data buffer
was recycled. Instead of waiting to recycle the Rx buffer only after all
processing was done on it (like accessing the parse results or timestamp
information), the code path just went ahead and re-used the buffer right
away.
This sometimes lead to corrupted HW and SW annotation areas.
Fix this by delaying the moment when the buffer is recycled.

Increase the needed headroom to account for a 64 byte alignment
restriction which, with this patch, we make mandatory on the Tx path.
The case in which the amount of headroom needed is not available is
already handled by the driver which instead sends a S/G frame with the
first buffer only holding the SW and HW annotation areas.
Without this patch, we can empirically see data corruption happening
between Tx and Tx confirmation which sometimes leads to the SW
annotation area being overwritten.
Since this is an old IP where the hardware team cannot help to
understand the underlying behavior, we make the Tx alignment mandatory
for all frames to avoid the crash on Tx conf. Also, remove the comment
that suggested that this is just an optimization.
This patch also sets the needed_headroom net device field to the usual
value that the driver would need on the Tx path:
- 64 bytes for the software annotation area
- 64 bytes to account for a 64 byte aligned buffer address

to mv88e6xxx_port_setup() which unconditionally expects pcs_ops to exist -
though the presence of the pcs_ops->pcs_init function is optional.
Modify code to check for pcs_ops first, before checking for and calling
pcs_ops->pcs_init. Modify checking and use of pcs_ops->pcs_teardown
which may potentially suffer the same problem.

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.
It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.
The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.
Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:
* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
models the kbd stops working for the first 2 - 5 minutes after boot
(waiting for EC watchdog reset?)
* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard
* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
https://github.com/yescallop/atkbd-nogetid
This has been tested on:
1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
in translated mode when no keyboard is plugged in and with a ps/2 kbd
a "AT Translated Set 2 keyboard" /dev/input/event# node shows up
2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)

- reverts of some PHY drivers that went into 6.7-rc1 that shouldn't
have been merged yet, the author is reworking them based on review
comments as they were using older apis that shouldn't be used
anymore for newer drivers
- small thunderbolt driver fixes for reported issues
- USB driver fixes for a variety of small issues in dwc3, typec,
xhci, and other smaller drivers.
- new device ids for usb-serial and onboard_usb_hub drivers.
All of these have been in linux-next with no reported issues"

- A fix for the swiotlb-xen driver which was missing the advertising of

which was rejected by the hypervisor

The current offset has the scale already applied to it. The ABI
documentation defines the offset parameter as "offset to be added
to <type>[Y]_raw prior to scaling by <type>[Y]_scale in order to
obtain value in the <type> units as specified in <type>[Y]_raw
documentation"
The right value is obtained at 0 degrees Celsius by the formula provided
in the datasheet:
T = Tsens_t0 + (Tadc_t - Tadc_t0) / Tadc_res
where:
T = 0 degrees Celsius
Tsens_t0 (reference temperature) = 25 degrees Celsius
Tadc_t0 (16-bit format for Tsens_t0) = 17508
Tadc_res = 60.1 LSB/degree Celsius
The resulting offset is 16005.5, which has been truncated to 16005 to
provide an integer value with a precision loss smaller than the 1-LSB
measurement precision.
Fix the offset to apply its value prior to scaling.

It is not always possible to keep a device in the runtime suspended state
when a system level suspend/resume cycle is executed. E.g. for ATA devices
connected to AHCI adapters, system resume resets the ATA ports, which
causes connected devices to spin up. In such case, a runtime suspended disk
will incorrectly be seen with a suspended runtime state because the device
is not resumed by sd_resume_system(). The power state seen by the user is
different than the actual device physical power state.
Fix this issue by introducing the struct scsi_device flag
force_runtime_start_on_system_start. When set, this flag causes
sd_resume_system() to request a runtime resume operation for runtime
suspended devices. This results in the user seeing the device runtime_state
as active after a system resume, thus correctly reflecting the device
physical power state.

Commit 3cc2ffe5c16d ("scsi: sd: Differentiate system and runtime start/stop
management") changed the single bit manage_start_stop flag into 2 boolean
fields of the SCSI device structure. Commit 24eca2dce0f8 ("scsi: sd:
Introduce manage_shutdown device flag") introduced the manage_shutdown
boolean field for the same structure. Together, these 2 commits increase
the size of struct scsi_device by 8 bytes by using booleans instead of
defining the manage_xxx fields as single bit flags, similarly to other
flags of this structure.
Avoid this unnecessary structure size increase and be consistent with the
definition of other flags by reverting the definitions of the manage_xxx
fields as single bit flags.

Some panel devices already depend on DRM device, like the panel in
arch/arm/boot/dts/st/ste-ux500-samsung-skomer.dts, because DRM device is
the ancestor of those panel devices. device_link_add() would fail by
returning a NULL pointer for those panel devices because of the existing
dependency. So, check the dependency by calling device_is_dependent()
before adding or deleting device link between panel device and DRM device
so that the link is managed only for independent panel devices.

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:
hi6220_reset.c:166:9: error: cast to smaller integer type 'enum hi6220_reset_ctrl_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

The pin descriptor should be returned if the name has been found in the
descriptor table. Remove the negation in the if statement for accurate
retrieval.

AM62Ax has 3 SPI channels where each channel has 4x TX and 4x RX
threads. Also fix the thread numbers to match what the firmware expects
according to the PSI-L device description.

Control flow integrity is now checking that type signatures match on
indirect function calls. That breaks closures, which embed a work_struct
in a closure in such a way that a closure_fn may also be used as a
workqueue fn by the underlying closure code.
So we have to change closure fns to take a work_struct as their
argument - but that results in a loss of clarity, as closure fns have
different semantics from normal workqueue functions (they run owning a
ref on the closure, which must be released with continue_at() or
closure_return()).
Thus, this patc introduces CLOSURE_CALLBACK() and closure_type() macros
as suggested by Kees, to smooth things over a bit.

Before returning the rswitch_start_xmit() in the error path,
dev_kfree_skb_any() should be called. So, fix it.
