Add interface to the FFA driver to allow for client drivers to request
and relinquish a notification as well as provide a callback for the
notification.

Enable client drivers to register a callback function that will be
called when one or more notifications are pending for a target

FFA_RUN is used by a scheduler to allocate CPU cycles to a target
endpoint execution context specified in the target information parameter.
If the endpoint execution context is in the waiting/blocked state, it
transitions to the running state.
Expose the ability to call FFA_RUN in order to give any partition in the
system cpu cycles to perform IMPDEF functionality.

Arm Firmware Framework for A-profile(FFA) v1.1 introduces notifications
and indirect messaging based upon notifications support and extends some
of the memory interfaces.
Let us add all the newly supported FF-A function IDs in the spec.
Also update to the error values and associated handling.

AMD GPU driver which was the only in-kernel user of iommu_v2 module
removed dependency on iommu_v2 module.
Also we are working on adding SVA support in AMD IOMMU driver. Device
drivers are expected to use common SVA framework to enable device
PASID/PRI features.
Removing iommu_v2 module and then adding SVA simplifies the development.
Hence remove iommu_v2 module.

Eric has reported that commit dabc8b207566 ("quota: fix dqput() to
follow the guarantees dquot_srcu should provide") heavily increases
runtime of generic/270 xfstest for ext4 in nojournal mode. The reason
for this is that ext4 in nojournal mode leaves dquots dirty until the last
dqput() and thus the cleanup done in quota_release_workfn() has to write
them all. Due to the way quota_release_workfn() is written this results
in synchronize_srcu() call for each dirty dquot which makes the dquot
cleanup when turning quotas off extremely slow.
To be able to avoid synchronize_srcu() for each dirty dquot we need to
rework how we track dquots to be cleaned up. Instead of keeping the last
dquot reference while it is on releasing_dquots list, we drop it right
away and mark the dquot with new DQ_RELEASING_B bit instead. This way we
can we can remove dquot from releasing_dquots list when new reference to
it is acquired and thus there's no need to call synchronize_srcu() each
time we drop dq_list_lock.

The generic PM domain is currently the only PM domain variant that supports
performance scaling. To allow performance scaling to be supported through a
common interface, let's add an optional callback ->set_performance_state(),
in the struct dev_pm_domain.
Moreover, let's add a function, dev_pm_domain_set_performance_state(), that
may be called by consumers to request a new performance state for a device
through its PM domain.
Note that, in most cases it's preferred that a consumer use the OPP library
to request a new performance state for its device. Although, this requires
some additional changes to be supported, which are being implemented from
subsequent changes.

The update to removing the eventfs_file changed the way the events top
level directory was handled. Instead of returning a dentry, it now returns
the eventfs_inode. In this changed, the removing of the events top level
directory is not much different than removing any of the other
directories. Because of this, the removal just called eventfs_remove_dir()
instead of eventfs_remove_events_dir().
Although eventfs_remove_dir() does the clean up, it misses out on the
dget() of the ei->dentry done in eventfs_create_events_dir(). It makes
more sense to match eventfs_create_events_dir() with a specific function
eventfs_remove_events_dir() and this specific function can then perform
the dput() to the dentry that had the dget() when it was created.

The allocation of struct io_buffer for metadata of provided buffers is
done through a custom allocator that directly gets pages and
fragments them. But, slab would do just fine, as this is not a hot path
(in fact, it is a deprecated feature) and, by keeping a custom allocator
implementation we lose benefits like tracking, poisoning,
sanitizers. Finally, the custom code is more complex and requires
keeping the list of pages in struct ctx for no good reason. This patch
cleans this path up and just uses slab.
I microbenchmarked it by forcing the allocation of a large number of
objects with the least number of io_uring commands possible (keeping
nbufs=USHRT_MAX), with and without the patch. There is a slight
increase in time spent in the allocation with slab, of course, but even
when allocating to system resources exhaustion, which is not very
realistic and happened around 1/2 billion provided buffers for me, it
wasn't a significant hit in system time. Specially if we think of a
real-world scenario, an application doing register/unregister of
provided buffers will hit ctx->io_buffers_cache more often than actually
going to slab.

The available_scan_mask is an array of bitmaps representing the channels
which can be simultaneously enabled by the driver. In many cases, the
hardware can offer more channels than what the user is interested in
obtaining. In such cases, it may be preferred that only a subset of
channels are enabled, and the driver reads only a subset of the channels
from the hardware.
Some devices can't support all channel combinations. For example, the
BM1390 pressure sensor must always read the pressure data in order to
acknowledge the watermark IRQ, while reading temperature can be omitted.
So, the available scan masks would be 'pressure and temperature' and
'pressure only'.
When IIO searches for the scan mask it asks the driver to use, it will
pick the first suitable one from the 'available_scan_mask' array. Hence,
ordering the masks in the array makes a difference. We should 'prefer'
reading just the pressure from the hardware (as it is a cheaper operation
than reading both pressure and temperature) over reading both pressure
and temperature. Hence, we should set the 'only pressure' as the first
scan mask in available_scan_mask array. If we set the 'pressure and
temperature' as first in the array, then the 'only temperature' will never
get used as 'pressure and temperature' can always serve the user's
needs.
Add (minimal) kerneldoc to the 'available_scan_mask' to hint the user
that the ordering of masks matters.

As of now, seeking in sysfs files is handled by generic_file_llseek().
There are situations where one may want to customize seeking logic:
- Many sysfs entries are fixed files while generic_file_llseek() accepts
past-the-end positions. Not only being useless by itself, this
also means a bug in userspace code will trigger not at lseek(), but at
some later point making debugging harder.
- generic_file_llseek() relies on f_mapping->host to get the file size
which might not be correct for all sysfs entries.
See commit 636b21b50152 ("PCI: Revoke mappings like devmem") as an example.
Implement llseek method to override this behavior at sysfs attribute
level. The method is optional, and if it is absent,
generic_file_llseek() is called to preserve backwards compatibility.

Comedi drivers can initialize an 8255 subdevice in I/O space by calling
`subdev_8255_init()`, or in memory-mapped I/O space by calling
`subdev_8255_mm_init()`, or by supplying a call-back function pointer
and context to either of those functions. Change it so that a new
function `subdev_8255_cb_init()` shall be called instead when supplying
a callback function and context, and remove the call-back function
parameter from `subdev_8255_init()` and `subdev_8255_mm_init()`.
Also rename `subdev_8255_init()` to `subdev_8255_io_init()`. The
parameters are changing, so might as well rename it at the same time.
Also rename the `regbase` member of `struct subdev_8255_private` to

Rework the comedi_8254 module to use a call-back function for register
access. This will make it easier to isolate the parts that will depend
on the `CONFIG_HAS_IOPORT` macro being defined and also allows the
possibility of supplying an external callback function during
initialization by a variant of the `comedi_8254_init()` and
`comedi_8254_mm_init()` functions, although that has not been
implemented yet.
The `struct comedi_8254` members have been changed to use a pointer to a
callback function and a context of type `unsigned long`. The
`comedi_8254_init()` and `comedi_8254_mm_init()` functions use an
internal callback function and set the context to the base address of
the registers (for `comedi_8254_mm_init()` that involves converting a
`void __iomem *` to `unsigned long`).
A minor change to `dio200_subdev_8254_offset()` in the
amplc_dio200_common module has been made due to the changes in `struct
comedi_8254`.

Remove support for md4 md5 hash and signatures in x.509 certificate
parsers, pkcs7 signature parser, authenticode parser.
All of these are insecure or broken, and everyone has long time ago
migrated to alternative hash implementations.
Also remove md2 & md3 oids which have already didn't have support.
This is also likely the last user of md4 in the kernel, and thus
crypto/md4.c and related tests in tcrypt & testmgr can likely be
removed. Other users such as cifs smbfs ext modpost sumversions have
their own internal implementation as needed.

When the Kunpeng accelerator executes tasks such as encryption
and decryption have minimum requirements on the number of device
queues. If the number of queues does not meet the requirement,
the process initialization will fail. Therefore, the driver checks
the number of queues on the device before registering the algorithm.
If the number does not meet the requirements, the driver does not register
the algorithm to crypto subsystem, the device is still added to the
qm_list.

If the queue isolation feature is enabled, the number of queues
supported by the device changes. When PF is enabled using the
current default number of queues, the default number of queues may
be greater than the number supported by the device. As a result,
the PF fails to be bound to the driver.
After modification, if queue isolation feature is enabled, when
the default queue parameter is greater than the number supported
by the device, the number of enabled queues will be changed to
the number supported by the device, so that the PF and driver
can be properly bound.

When a fence signals there is a very small race window where the timestamp
isn't updated yet. sync_file solves this by busy waiting for the
timestamp to appear, but on other ocassions didn't handled this
correctly.
Provide a dma_fence_timestamp() helper function for this and use it in
all appropriate cases.
Another alternative would be to grab the spinlock when that happens.
v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case
the accurate timestamp is needed and/or the timestamp is not based on

When calling mcb_bus_add_devices(), both mcb devices and the mcb
bus will attempt to attach a device to a driver because they share
the same bus_type. This causes an issue when trying to cast the
container of the device to mcb_device struct using to_mcb_device(),
leading to a wrong cast when the mcb_bus is added. A crash occurs
when freing the ida resources as the bus numbering of mcb_bus gets
confused with the is_added flag on the mcb_device struct.
The only reason for this cast was to keep an is_added flag on the
mcb_device struct that does not seem necessary. The function
device_attach() handles already bound devices and the mcb subsystem
does nothing special with this is_added flag so remove it completely.

Florian Westphal says:
====================
netfilter patches for net
First patch resolves a regression with vlan header matching, this was
broken since 6.5 release. From myself.
Second patch fixes an ancient problem with sctp connection tracking in
case INIT_ACK packets are delayed. This comes with a selftest, both
patches from Xin Long.
Patch 4 extends the existing nftables audit selftest, from
Phil Sutter.
Patch 5, also from Phil, avoids a situation where nftables
would emit an audit record twice. This was broken since 5.13 days.
Patch 6, from myself, avoids spurious insertion failure if we encounter an
overlapping but expired range during element insertion with the
'nft_set_rbtree' backend. This problem exists since 6.2.

Instead of having a descriptor for every file represented in the eventfs
directory, only have the directory itself represented. Change the API to
send in a list of entries that represent all the files in the directory
(but not other directories). The entry list contains a name and a callback
function that will be used to create the files when they are accessed.
struct eventfs_inode *eventfs_create_events_dir(const char *name, struct dentry *parent,
const struct eventfs_entry *entries,
int size, void *data);
is used for the top level eventfs directory, and returns an eventfs_inode
that will be used by:
struct eventfs_inode *eventfs_create_dir(const char *name, struct eventfs_inode *parent,
const struct eventfs_entry *entries,
int size, void *data);
where both of the above take an array of struct eventfs_entry entries for
every file that is in the directory.
The entries are defined by:
typedef int (*eventfs_callback)(const char *name, umode_t *mode, void **data,
const struct file_operations **fops);
struct eventfs_entry {
const char *name;
eventfs_callback callback;
};
Where the name is the name of the file and the callback gets called when
the file is being created. The callback passes in the name (in case the
same callback is used for multiple files), a pointer to the mode, data and
fops. The data will be pointing to the data that was passed in
eventfs_create_dir() or eventfs_create_events_dir() but may be overridden
to point to something else, as it will be used to point to the
inode->i_private that is created. The information passed back from the
callback is used to create the dentry/inode.
If the callback fills the data and the file should be created, it must
return a positive number. On zero or negative, the file is ignored.
This logic may also be used as a prototype to convert entire pseudo file
systems into just-in-time allocation.
The "show_events_dentry" file has been updated to show the directories,
and any files they have.
With just the eventfs_file allocations:

rcu_report_dead() and rcutree_migrate_callbacks() have their headers in
rcupdate.h while those are pure rcutree calls, like the other CPU-hotplug
functions.
Also rcu_cpu_starting() and rcu_report_dead() have different naming
conventions while they mirror each other's effects.
Fix the headers and propose a naming that relates both functions and
aligns with the prefix of other rcutree CPU-hotplug functions.

Among the three CPU-hotplug teardown RCU callbacks, two of them early
exit if CONFIG_HOTPLUG_CPU=n, and one is left unchanged. In any case
all of them have an implementation when CONFIG_HOTPLUG_CPU=n.
Align instead with the common way to deal with CPU-hotplug teardown
callbacks and provide a proper stub when they are not supported.

This series from Patrisious extends mlx5 to support IPsec packet offload
in multiport devices (MPV, see [1] for more details).
These devices have single flow steering logic and two netdev interfaces,
which require extra logic to manage IPsec configurations as they performed
on netdevs.
