The function ata_schedule_scsi_eh() was removed with commit
f8bbfc247efb ("[PATCH] SCSI: make scsi_implement_eh() generic API for
SCSI transports"), and the function ata_sff_irq_clear() was removed
with commit 37f65b8bc262("libata-sff: ata_sff_irq_clear() is BMDMA
specific").
Remove the now useless declarations of these functions in
drivers/ata/libata.h and include/linux/libata.h.

Currently, we copy the mtime and ctime to the in-core inode and then
mark the inode dirty. This is fine for certain types of filesystems, but
not all. Some require a real setattr to properly change these values
(e.g. ceph or reexported NFS).
Fix this code to call notify_change() instead, which is the proper way
to effect a setattr. There is one problem though:
In this case, the client is holding a write delegation and has sent us
attributes to update our cache. We don't want to break the delegation
for this since that would defeat the purpose. Add a new ATTR_DELEG flag
that makes notify_change bypass the try_break_deleg call.

pstore_dump() is called when both preemption and local IRQ are disabled,
and a spinlock is obtained, which is problematic for the RT kernel because
in this configuration, spinlocks are sleep locks.
Replace the spinlock_t with raw_spinlock_t to avoid sleeping in atomic context.

Normally, the type of enums is "unsigned int" or "int". GCC has
the "-fshort-enums" option, which instructs the compiler to
use the smallest data type that can hold all the values in
the enum (i.e: char, short, int or their unsigned variants).
According to the GCC documentation, "-fshort-enums" may be
default on some targets. This seems to be the case for SOF
when built for a certain 32-bit ARM platform.
On Linux, this is not the case (tested with "aarch64-linux-gnu-gcc")
which means enums such as "enum sof_comp_type" will end up having
different sizes on Linux and SOF. Since "enum sof_comp_type" is used in
IPC-related structures such as "struct sof_ipc_comp", this means
the fields of the structures will end up being placed at different
offsets. This, in turn, leads to SOF not being able to properly
interpret data passed from Linux.
With this in mind, replace "enum sof_comp_type" from
"struct sof_ipc_comp" with "uint32_t".

Allowing iounmap() on memory that was not ioremap()'d in the first
place is obviously a bad idea. There is currently a feeble attempt to
avoid errant iounmap()s by checking to see if the address is below
"high_memory". But that's imprecise at best because there are plenty
of high addresses that are also invalid to call iounmap() on.
Thankfully, there is a more precise helper: is_ioremap_addr(). x86
just does not use it in iounmap().
Restrict iounmap() to addresses in the ioremap region, by using
is_ioremap_addr(). This aligns x86 closer to the generic iounmap()
implementation.
Additionally, add a warning in case there is an attempt to iounmap()
invalid memory. This replaces an existing silent return and will
help alert folks to any incorrect usage of iounmap().
Due to VMALLOC_START on i386 not being present in asm/pgtable.h,
include for asm/vmalloc.h had to be added to include/linux/ioremap.h.

Enhance the ethtool cable test interface by introducing the ability to
specify the source of the diagnostic information for cable test results.
This is particularly useful for PHYs that offer multiple diagnostic
methods, such as Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD).
Key changes:
- Added `ethnl_cable_test_result_with_src` and
`ethnl_cable_test_fault_length_with_src` functions to allow specifying
the information source when reporting cable test results.
- Updated existing `ethnl_cable_test_result` and
`ethnl_cable_test_fault_length` functions to use TDR as the default
source, ensuring backward compatibility.
- Modified the UAPI to support these new attributes, enabling drivers to
provide more detailed diagnostic information.

Extend the ethtool netlink cable testing interface by adding support for
specifying the source of cable testing results. This allows users to
differentiate between results obtained through different diagnostic
methods.
For example, some TI 10BaseT1L PHYs provide two variants of cable
diagnostics: Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD). By introducing `ETHTOOL_A_CABLE_RESULT_SRC` and
`ETHTOOL_A_CABLE_FAULT_LENGTH_SRC` attributes, this update enables
drivers to indicate whether the result was derived from TDR or ALCD,
improving the clarity and utility of diagnostic information.

When sending a RDMA_CM_REQUEST, the NVMe RDMA Transport Specification
allows you to populate the cntlid field in the RDMA_CM_REQUEST Private
Data.
The cntlid is returned by the target on completion of the first
RDMA_CM_REQUEST command (which creates the admin queue).
The cntlid field can then be populated by the host when the I/O queues
are created (using additional RDMA_CM_REQUEST commands), such that the
target can perform extra validation for additional RDMA_CM_REQUEST
commands.
This additional error code and error message is also added, such that
nvme_rdma_cm_msg() will display the proper error message if the target
fails the RDMA_CM_REQUEST command because of this extra validation.

ARL and MTL share a single GSC firmware blob. However, ARL requires a
newer version of it.
So add differentiate of the PCI ids for ARL from MTL and create ARL as
a sub-platform of MTL. That way, all the existing workarounds and such
still treat ARL as MTL exactly as before. However, now the GSC code
can check for ARL and do an extra version check on the firmware before
committing to it.
Also, the version extraction code has various ways of failing but the
return code was being ignore and so the firmware load would attempt to
continue anyway. Fix that by propagating the return code to the next
level out.

The v4l2_subdev_link_validate() helper function is meant to be used as a
drop-in implementation of a V4L2 subdev entity .link_validate() handler.
It supports subdev-to-subdev links only, and complains if one end of the
link is not a subdev. This forces drivers that have video output devices
connected to subdevs to implement a custom .link_validate() handler,
calling v4l2_subdev_link_validate() for the subdev-to-subdev links, and
performing manual link validation for the video-to-subdev links.
Video devices embed a media entity, and therefore also have a
.link_validate() operation. For video capture devices, the operation
should be manually implemented by drivers for validate the
subdev-to-video links. For video output devices, on the other hand, that
operation is never called, as link validation is performed in the
context of the sink entity.
As a result, we end up forcing drivers to implement a custom
.link_validate() handler for subdevs connected to video output devices,
when the video devices provide an operation that could be used for that
purpose.
To improve that situation, make v4l2_subdev_link_validate() delegate
link validation to the source's .link_validate() operation when the link
source is a video device and the link sink is a subdev. This allows
broader usage of v4l2_subdev_link_validate(), and simplifies drivers by
making video device link validation easy to implement in the video
device .link_validate(), regardless of whether the video device is an
output device or a capture device.

Modules registering drivers with usb_serial_register_drivers() might

Krzysztof reported an issue [0] which is caused by parallel attempts to
instantiate the same I2C client device. This can happen if driver
supports auto-detection, but certain devices are also instantiated
explicitly.
The original change isn't actually wrong, it just revealed that I2C core
isn't prepared yet to handle this scenario.
Calls to i2c_new_client_device() can be nested, therefore we can't use a
simple mutex here. Parallel instantiation of devices at different addresses
is ok, so we just have to prevent parallel instantiation at the same address.
We can use a bitmap with one bit per 7-bit I2C client address, and atomic
bit operations to set/check/clear bits.
Now a parallel attempt to instantiate a device at the same address will
result in -EBUSY being returned, avoiding the "sysfs: cannot create duplicate
filename" splash.
Note: This patch version includes small cosmetic changes to the Tested-by
version, only functional change is that address locking is supported
for slave addresses too.

kunit_driver_create() accepts a name for the driver, but does not copy
it, so if that name is either on the stack, or otherwise freed, we end
up with a use-after-free when the driver is cleaned up.
Instead, strdup() the name, and manage it as another KUnit allocation.
As there was no existing kunit_kstrdup(), we add one. Further, add a
kunit_ variant of strdup_const() and kfree_const(), so we don't need to
allocate and manage the string in the majority of cases where it's a
constant.
However, these are inline functions, and is_kernel_rodata() only works
for built-in code. This causes problems in two cases:
- If kunit is built as a module, __{start,end}_rodata is not defined.
- If a kunit test using these functions is built as a module, it will
suffer the same fate.
This fixes a KASAN splat with overflow.overflow_allocation_test, when
built as a module.
Restrict the is_kernel_rodata() case to when KUnit is built as a module,
which fixes the first case, at the cost of losing the optimisation.
Also, make kunit_{kstrdup,kfree}_const non-inline, so that other modules
using them will not accidentally depend on is_kernel_rodata(). If KUnit
is built-in, they'll benefit from the optimisation, if KUnit is not,
they won't, but the string will be properly duplicated.

The 'mmc_context_info' structure is unused.
It has been introduced in:
- commit 2220eedfd7ae ("mmc: fix async request mechanism for sequential
read scenarios")
in 2013-02 and its usages have been removed in:
- commit 126b62700386 ("mmc: core: Remove code no longer needed after the
switch to blk-mq")
- commit 0fbfd1251830 ("mmc: block: Remove code no longer needed after
the switch to blk-mq")
in 2017-12.
Now remove this unused structure.

A number of storage technologies support a specialised hardware
partition designed to be resistant to replay attacks. The underlying
HW protocols differ but the operations are common. The RPMB partition
cannot be accessed via standard block layer, but by a set of specific
RPMB commands. Such a partition provides authenticated and replay
protected access, hence suitable as a secure storage.
The initial aim of this patch is to provide a simple RPMB driver
interface which can be accessed by the optee driver to facilitate early
RPMB access to OP-TEE OS (secure OS) during the boot time.
A TEE device driver can claim the RPMB interface, for example, via
rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver
provides a callback to route RPMB frames to the RPMB device accessible
via rpmb_route_frames().
The detailed operation of implementing the access is left to the TEE
device driver itself.

Subtract network offset to skb->len before performing IPv4 header sanity
checks, then adjust transport offset from offset from mac header.
Jorge Ortiz says:
When small UDP packets (< 4 bytes payload) are sent from eth0,
`meta l4proto udp` condition is not met because `NFT_PKTINFO_L4PROTO` is
not set. This happens because there is a comparison that checks if the
transport header offset exceeds the total length. This comparison does
not take into account the fact that the skb network offset might be
non-zero in egress mode (e.g., 14 bytes for Ethernet header).

Expose min_wait_usec in io_uring_getevents_arg, replacing the pad member
that is currently in there. The value is in usecs, which is explained in
the name as well.
Note that if min_wait_usec and a normal timeout is used in conjunction,
the normal timeout is still relative to the base time. For example, if
min_wait_usec is set to 100 and the normal timeout is 1000, the max
total time waited is still 1000. This also means that if the normal
timeout is shorter than min_wait_usec, then only the min_wait_usec will
take effect.
See previous commit for an explanation of how this works.
IORING_FEAT_MIN_TIMEOUT is added as a feature flag for this, as
applications doing submit_and_wait_timeout() style operations will
generally not see the -EINVAL from the wait side as they return the
number of IOs submitted. Only if no IOs are submitted will the -EINVAL
bubble back up to the application.

timespec argument specifies the maximum time it can wait for, add
support for the absolute mode, with the value carrying a CLOCK_MONOTONIC
absolute time until which we should return control back to the user.

When net devices propagate xdp configurations to slave devices,
we will need to perform a memory provider check to ensure we're
not binding xdp to a device using unreadable netmem.
Currently the ->ndo_bpf calls in a few places. Adding checks to all
these places would not be ideal.
Refactor all the ->ndo_bpf calls into one place where we can add this
check in the future.

Algorithm registration is usually carried out during module init,
where as little work as possible should be carried out. The SIMD
code violated this rule by allocating a tfm, this then triggers a
full test of the algorithm which may dead-lock in certain cases.
SIMD is only allocating the tfm to get at the alg object, which is
in fact already available as it is what we are registering. Use
that directly and remove the crypto_alloc_tfm call.
Also remove some obsolete and unused SIMD API.

No consumers anymore, remove it. After this, insertion of policies
no longer require list walk of all inexact policies but only those
that are reachable via the candidate sets.
This gives almost linear insertion speeds provided the inserted
policies are for non-overlapping networks.
Before:
Inserted 1000 policies in 70 ms
Inserted 10000 policies in 1155 ms
Inserted 100000 policies in 216848 ms
After:
Inserted 1000 policies in 56 ms
Inserted 10000 policies in 478 ms
Inserted 100000 policies in 4580 ms
Insertion of 1m entries takes about ~40s after this change
on my test vm.
