When switching network namespaces with the bpf_redirect_peer helper, the
skb->mark and skb->tstamp fields are not zeroed out like they can be on
a typical netns switch. This patch clarifies that in the helper
description.

Don't have the other users that do things at panic time (the watchdog)
do all this themselves, provide a function to do it.
Also, with the new design where most stuff happens at thread context,
a few things needed to be fixed to avoid doing locking in a panic
context.

XFS will be able to support large atomic writes (atomic write > 1x block)
in future. This will be achieved by using different operating methods,
depending on the size of the write.
Specifically a new method of operation based in FS atomic extent remapping
will be supported in addition to the current HW offload-based method.
The FS method will generally be appreciably slower performing than the
HW-offload method. However the FS method will be typically able to
contribute to achieving a larger atomic write unit max limit.
XFS will support a hybrid mode, where HW offload method will be used when
possible, i.e. HW offload is used when the length of the write is
supported, and for other times FS-based atomic writes will be used.
As such, there is an atomic write length at which the user may experience
appreciably slower performance.
Advertise this limit in a new statx field, stx_atomic_write_unit_max_opt.
When zero, it means that there is no such performance boundary.
Masks STATX{_ATTR}_WRITE_ATOMIC can be used to get this new field. This is
ok for older kernels which don't support this new field, as they would
report 0 in this field (from zeroing in cp_statx()) already. Furthermore
those older kernels don't support large atomic writes - apart from block
fops, but there would be consistent performance there for atomic writes
in range [unit min, unit max].

arch_topology.c provides functionality to parse and scale CPU capacity.
It also provides a corresponding sysfs interface. Some architectures
parse and scale CPU capacity differently as per their own needs. On
Intel processors, for instance, it is responsibility of the Intel
P-state driver.
Relocate the implementation of that interface to a common location in
topology.c. Architectures can use the interface and populate it using
their own mechanisms.
An alternative approach would be to compile arch_topology.c even if
not needed only to get this interface. This approach would create
duplicated and conflicting functionality and data structures.

Doing cpufreq-specific EAS checks that require accessing policy
internals directly from sched_is_eas_possible() is a bit unfortunate,
so introduce cpufreq_ready_for_eas() in cpufreq, move those checks
into that new function and make sched_is_eas_possible() call it.
While at it, address a possible race between the EAS governor check
and governor change by doing the former under the policy rwsem.

Add device tree bindings for the TH1520 Video Output (VO) subsystem
clock controller. The VO sub-system manages clock gates for multimedia
components including HDMI, MIPI, and GPU.
Document the VIDEO_PLL requirements for the VO clock controller, which
receives its input from the AP clock controller. The VIDEO_PLL is a
Silicon Creations Sigma-Delta (integer) PLL typically running at 792 MHz
with maximum FOUTVCO of 2376 MHz.
This binding complements the existing AP sub-system clock controller
which manages CPU, DPU, GMAC and TEE PLLs.

Add a new Kconfig CONFIG_UBSAN_KVM_EL2 for KVM which enables
UBSAN for EL2 code (in protected/nvhe/hvhe) modes.
This will re-use the same checks enabled for the kernel for
the hypervisor. The only difference is that for EL2 it always
emits a "brk" instead of implementing hooks as the hypervisor
can't print reports.
The KVM code will re-use the same code for the kernel
"report_ubsan_failure()" so #ifdefs are changed to also have this

- revert device path canonicalization, this does not work as intended
with namespaces and is not reliable in all setups
- fix crash in scrub when checksum tree is not valid, e.g. when mounted
with rescue=ignoredatacsums
- fix crash when tracepoint btrfs_prelim_ref_insert is enabled
- other minor fixups:
- open code folio_index(), meant to be used in MM code
- use matching type for sizeof in compression allocation
* tag 'for-6.15-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
btrfs: open code folio_index() in btree_clear_folio_dirty_tag()
Revert "btrfs: canonicalize the device path before adding it"
btrfs: avoid NULL pointer dereference if no valid csum tree
btrfs: handle empty eb->folios in num_extent_folios()
btrfs: correct the order of prelim_ref arguments in btrfs__prelim_ref
btrfs: compression: adjust cb->compressed_folios allocation type

There is no in-tree user of "include/sound/cs42l52.h", so move
'struct cs42l52_platform_data ' to cs42l52.c and remove the header file.
And platform data is mostly for legacy platforms that create devices
non using device tree. So drop cs42l52.h to prepare using GPIOD API.

And platform data is mostly for platforms that create

there is less possibility that new users will use legacy method
to create devices. So drop cs42l56.h to prepare using GPIOD API.

SOF driver will load required function topologies dynamically. However,
we prefer using the monolithic topology. Add a flag to allow user not
using the function topologies.

Allow userspace to pass a per-I/O write stream in the SQE:
__u8 write_stream;
The __u8 type matches the size the filesystems and block layer support.
Application can query the supported values from the block devices
max_write_streams sysfs attribute. Unsupported values are ignored by
file operations that do not support write streams or rejected with an
error by those that support them.

many are available so applications can generically query this.

Add the ability to pass a write stream for placement control in the bio.
The new field fits in an existing hole, so does not change the size of
the struct.
