Currently all flows for a certain SA must be processed by the same
cpu to avoid packet reordering and lock contention of the xfrm
state lock.
To get rid of this limitation, the IETF standardized per cpu SAs
in RFC 9611. This patch implements the xfrm part of it.
We add the cpu as a lookup key for xfrm states and a config option
to generate acquire messages for each cpu.
With that, we can have on each cpu a SA with identical traffic selector
so that flows can be processed in parallel on all cpus.

Introduce new flag (IOMMU_HWPT_ALLOC_PASID) to domain_alloc_users() ops.
If IOMMU supports PASID it will allocate domain. Otherwise return error.
In error path check for -EOPNOTSUPP and try to allocate non-PASID
domain so that DMA-API mode work fine for drivers which does not support
PASID as well.
Also modify __iommu_group_alloc_default_domain() to call
iommu_paging_domain_alloc_flags() with appropriate flag when allocating
paging domain.

The third parameter to _IOR et al is a type name, not a size. So the
parameter being named "size" is irritating. Rename it to "argtype"
instead to reduce confusion.
There is a very minor chance that this breaks stuff. It only hurts
however if there is a variable (or macro) in userspace that is called
"argtype" *and* it's used in the parameters of _IOR and friends. IMHO
this is negligible because usually definitions making use of these
macros are provided by kernel headers (i.e. us) or if they are
replicated in userspace code, they are replicated and so supposed to
match the kernel definitions (e.g. to make them usable by programs
without the need to update the kernel headers used to compile the
program).

There is a requirement to expose the audio hardware that accelerates various
tasks for user space such as sample rate converters, compressed
stream decoders, etc.
This is description for the API extension for the compress ALSA API which
is able to handle "tasks" that are not bound to real-time operations
and allows for the serialization of operations.

RISC-V supports pointer masking with a variable number of tag bits
(which is called "PMLEN" in the specification) and which is configured
at the next higher privilege level.
Wire up the PR_SET_TAGGED_ADDR_CTRL and PR_GET_TAGGED_ADDR_CTRL prctls
so userspace can request a lower bound on the number of tag bits and
determine the actual number of tag bits. As with arm64's
PR_TAGGED_ADDR_ENABLE, the pointer masking configuration is
thread-scoped, inherited on clone() and fork() and cleared on execve().

A common pattern when using pid fds is having to get information
about the process, which currently requires /proc being mounted,
resolving the fd to a pid, and then do manual string parsing of
/proc/N/status and friends. This needs to be reimplemented over
and over in all userspace projects (e.g.: I have reimplemented
resolving in systemd, dbus, dbus-daemon, polkit so far), and
requires additional care in checking that the fd is still valid
after having parsed the data, to avoid races.
Having a programmatic API that can be used directly removes all
these requirements, including having /proc mounted.
As discussed at LPC24, add an ioctl with an extensible struct
so that more parameters can be added later if needed. Start with
returning pid/tgid/ppid and creds unconditionally, and cgroupid
optionally.

This allows users to prevent a vif from affecting radios other than the
configured ones. This can be useful in cases where e.g. an AP is running
on one radio, and triggering a scan on another radio should not disturb it.
Changing the allowed radios list for a vif is supported, but only while
it is down.
While it is possible to achieve the same by always explicitly specifying
a frequency list for scan requests and ensuring that the wrong channel/band
is never accidentally set on an unrelated interface, this change makes
multi-radio wiphy setups a lot easier to deal with for CLI users.
By itself, this patch only enforces the radio mask for scanning requests
and remain-on-channel. Follow-up changes build on this to limit configured
frequencies.

ublk currently supports the following behaviors on ublk server exit:
A: outstanding I/Os get errors, subsequently issued I/Os get errors
B: outstanding I/Os get errors, subsequently issued I/Os queue
C: outstanding I/Os get reissued, subsequently issued I/Os queue
and the following behaviors for recovery of preexisting block devices by
a future incarnation of the ublk server:
1: ublk devices stopped on ublk server exit (no recovery possible)
2: ublk devices are recoverable using start/end_recovery commands
The userspace interface allows selection of combinations of these
behaviors using flags specified at device creation time, namely:
default behavior: A + 1
UBLK_F_USER_RECOVERY: B + 2
UBLK_F_USER_RECOVERY|UBLK_F_USER_RECOVERY_REISSUE: C + 2
The behavior A + 2 is currently unsupported. Add support for this

When working in "fd mode", fanotify_read() needs to open an fd
from a dentry to report event->fd to userspace.
Opening an fd from dentry can fail for several reasons.
For example, when tasks are gone and we try to open their
/proc files or we try to open a WRONLY file like in sysfs
or when trying to open a file that was deleted on the
remote network server.
Add a new flag FAN_REPORT_FD_ERROR for fanotify_init().
For a group with FAN_REPORT_FD_ERROR, we will send the
event with the error instead of the open fd, otherwise
userspace may not get the error at all.
For an overflow event, we report -EBADF to avoid confusing FAN_NOFD
with -EPERM. Similarly for pidfd open errors we report either -ESRCH
or the open error instead of FAN_NOPIDFD and FAN_EPIDFD.
In any case, userspace will not know which file failed to
open, so add a debug print for further investigation.

Add support for frame-based frame format, which can be used to support
multiple formats like H264 or H265, in addition to MJPEG and YUV frames.
The frame-based format is set to H264 by default, but it can be updated
to other formats by modifying the GUID through the guid configfs
attribute. Different structures are used for all three formats, as
H264 has a different structure compared to MJPEG and uncompressed
formats. These structures will be passed to the frame make function
based on the active format, using a common frame structure with
additional parameters needed only for frame-based formats. These
parameters are handled at runtime in the UVC driver.

Add support for Raspberry Pi CFE. The CFE is a hardware block that
contains:
- MIPI D-PHY
- MIPI CSI-2 receiver
- Front End ISP (FE)
The driver has been upported from the Raspberry Pi kernel commit
88a681df9623 ("ARM: dts: bcm2712-rpi: Add i2c<n>_pins labels").

Add two meta formats for PiSP FE: V4L2_META_FMT_RPI_FE_CFG and
V4L2_META_FMT_RPI_FE_STATS. The former is used to provide configuration

Hardcoded driver date is useless, so use kernel version as a driver date
to make identifying .ko file easier. Also allow to pass DRIVER_DATE

The user thresholds mechanism is a way to have the userspace to tell
the thermal framework to send a notification when a temperature limit
is crossed. There is no id, no hysteresis, just the temperature and
the direction of the limit crossing. That means we can be notified
when a threshold is crossed the way up only, or the way down only or
both ways. That allows to create hysteresis values if it is needed.
A threshold can be added, deleted or flushed. The latter means all
thresholds belonging to a thermal zone will be deleted.
When a threshold is added:
- if the same threshold (temperature and direction) exists, an error
is returned
- if a threshold is specified with the same temperature but a
different direction, the specified direction is added
- if there is no threshold with the same temperature then it is
created
When a threshold is deleted:
- if the same threshold (temperature and direction) exists, it is
deleted
- if a threshold is specified with the same temperature but a
different direction, the specified direction is removed
- if there is no threshold with the same temperature, then an error
is returned
When the threshold are flushed:
- All thresholds related to a thermal zone are deleted
When a threshold is crossed:
- the userspace does not need to know which threshold(s) have been
crossed, it will be notified with the current temperature and the
previous temperature
- if multiple thresholds have been crossed between two updates only
one notification will be send to the userspace, it is pointless to
send a notification per thresholds crossed as the userspace can
handle that easily when it has the temperature delta information

The documentation says CONFIG_FUNCTION_ERROR_INJECTION is supported only
on x86. This was presumably true at the time of writing, but it's now
supported on many other architectures too. Drop this statement, since
it's not correct anymore and it fits better in other documentation
anyway.
