This patch supports to report fserror, it provides another way to let
userspace to monitor filesystem level error. In addition, it exports
/sys/fs/f2fs/features/fserror once f2fs kernel module start to support
the new feature, then generic/791 of fstests can notice the feature,
and verify validation of fserror report.

From: Wenjie Qi <qiwenjie@xiaomi.com>
F2FS already classifies DATA writes using its existing hot, warm and cold
temperature policy, but it only passes that intent down as a write hint.
That hint alone is not sufficient for NVMe FDP placement, because the
current NVMe command path consumes `bio->bi_write_stream` rather than
`bio->bi_write_hint` when selecting a placement ID.
When the target block device exposes write streams, map the existing F2FS
DATA temperature classes onto stream IDs and set `bio->bi_write_stream`
for both buffered and direct writes. If the device exposes no write
streams, keep the current behavior by leaving the stream unset.
The stream mapping is evaluated against the target block device of each
bio, so the existing per-device fallback behavior stays unchanged for
multi-device filesystems. Existing blkzoned restrictions also remain in
place.
The mapping is intentionally small and deterministic:
- 1 stream: hot, warm and cold all use stream 1
- 2 streams: hot/warm use 1, cold uses 2
- 3+ streams: hot uses 1, warm uses 2, cold uses 3

Currently this binding only lists i2s and dsp_b formats that are used
by existing sound cards. However, DT bindings should describe the full
hardware capabilities rather than only the formats of current usage.
The SAI audio controller of i.MX audio sound card supports multiple DAI
formats, including:
- i2s
- left_j
- right_j
- dsp_a
- dsp_b
- pdm
- msb
- lsb
Complete the full list of formats supported by i.MX audio sound card to
ensure the binding correctly describes hardware.

Pull networking fixes from Jakub Kicinski:
"Including fixes from Bluetooth, wireless and netfilter.
Craziness continues with no end in sight. Even discounting the driver
revert this is a pretty huge PR for standards of the previous era. I'd
speculate - we haven't seen the worst of it, yet. Good news, I guess,
is that so far we haven't seen many (any?) cases of "AI reported a
bug, we fixed it and a real user regressed".
Current release - fix to a fix:
- Bluetooth: btmtk: accept too short WMT FUNC_CTRL events
- vsock/virtio: relax the recently added memory limit a little
Current release - regressions:
- IB/IPoIB: make sure IB drivers always use async set_rx_mode since
some (mlx5) are now required to use it due to locking changes
Previous releases - regressions:
- udp: fix UDP length on last GSO_PARTIAL segment
- af_unix: fix UAF read of tail->len in unix_stream_data_wait()
- tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction
- mlx5e: fix unlocked writing to ICOSQ, breaking AF_XDP
Previous releases - always broken:
- tap: fix stack info leak in tap_ioctl() SIOCGIFHWADDR
- ipv4: raw: reject IP_HDRINCL packets with ihl < 5
- Bluetooth: a lot of locking and concurrency fixes (as always)
- batman-adv (mesh wireless networking): a lot of random fixes for
issues reported by security researchers and Sashiko
- netfilter: same thing, a lot of small security-ish fixes all over

Add an auxiliary-bus hwmon driver for the temperature sensor exposed by
AMD Promontory 21 (PROM21) xHCI PCI functions. The driver binds to the
"hwmon" auxiliary device published by the PROM21 xHCI PCI glue and
exposes the sensor as temp1_input under the prom21_xhci hwmon device.
The sensor is accessed through a PROM21 vendor index/data register pair
in the xHCI PCI MMIO BAR. The driver consumes parent-provided MMIO data
from the PROM21 PCI glue instead of inspecting the parent PCI driver's
drvdata. The read path restores the previous vendor index value after
sampling and does not runtime-resume the parent PCI device; reads from a
suspended parent return -ENODATA.
Document the supported device, register access, runtime PM behavior, and
sysfs lookup method. The documentation also records the observation
method used to identify the register pair and derive the conversion
formula.

This document is motivated by the ongoing maintenance burden that
abandoned and untestable filesystems impose on VFS developers, blocking
infrastructure changes such as folio conversions and iomap migration.
This week alone, two new filesystems were proposed on linux-fsdevel
(VMUFAT and FTRFS), highlighting the need for documented guidelines
that new filesystem authors can refer to before submission.
Multiple recent discussions on linux-fsdevel have touched on the
criteria for merging new filesystems and for deprecating old ones,
covering topics such as modern VFS interface adoption, testability,
userspace utilities, maintainer commitment, and user base viability.
Add Documentation/filesystems/adding-new-filesystems.rst describing
the technical requirements and community expectations for merging a
new filesystem into the kernel. The guidelines cover:
- Alternatives to consider before proposing a new in-kernel filesystem
- Technical requirements: modern VFS interfaces (iomap, folios,
fs_context mount API), testability, and userspace utilities
- Community expectations: identified maintainers, demonstrated
commitment, sustained backing, and a clear user base
- Ongoing obligations after merging, including the risk of deprecation
for unmaintained filesystems

Add bindings for NETC switch. This switch is a PCIe function of NETC IP,
it supports advanced QoS with 8 traffic classes and 4 drop resilience
levels, and a full range of TSN standards capabilities. The switch CPU
port connects to an internal ENETC port, which is also a PCIe function
of NETC IP. So these two ports use a light-weight "pseudo MAC" instead
of a back-to-back MAC, because the "pseudo MAC" provides the delineation
between switch and ENETC, this translates to lower power (less logic and
memory) and lower delay (as there is no serialization delay across this
link).

The current description indicates that the 'dsa,member' property cannot
be set for a switch that is not part of any cluster. Vladimir thinks
that this is a case where the actual technical limitation was poorly
transposed into words when this restriction was first documented, in
commit 8c5ad1d6179d ("net: dsa: Document new binding").
The true technical limitation is that many DSA tagging protocols are
topology-unaware, and always call dsa_conduit_find_user() with a
switch_id of 0. Specifying a custom "dsa,member" property with a
non-zero switch_id would break them.
Therefore, for topology-aware switches, it is fine to specify this
property for them, even if they are not part of any cluster. Our NETC
switch is a good example which is topology-aware, the switch_id is
carried in the switch tag, but the switch_id 0 is reserved for VEPA
switch and cannot be used, so we need to use this property to assign
a non-zero switch_id for it.

Add a new compatible for the RGA3 (Raster Graphic Acceleration 3)
peripheral found on the RK3588 SoC. Also specify an iommu property,
as the RGA3 contains the generic rockchip iommu. While other versions
also have an iommu, it's usually specific to them.
The RK3588 contains one RGA2-Enhance core (also contained on the RK3399)
and two RGA3 cores. Both feature a similar functionality of scaling,
cropping and rotating of up to two input images into one output image.
Key differences of the RGA3 are:

Document two optional cells in eswin,hsp-sp-csr for the TXD and RXD
delay control register offsets.
These registers are used by the driver to clear any residual delay
configuration left by the bootloader, ensuring that MAC-side RGMII delay
settings are applied solely according to the kernel configuration.
Add a reference to the EIC7700X SoC Technical Reference Manual for
background information about the HSP CSR block.

KF_ARG_PTR_TO_LIST_NODE normally requires an owning reference
(PTR_TO_BTF_ID | MEM_ALLOC with ref_obj_id). Introduce the
__nonown_allowed annotation on selected list-node arguments so
non-owning references with ref_obj_id==0 are accepted as well.
This patch only adds the generic verifier support and documents the
annotation. Later patches in the series will apply it to bpf_list_add
/del(), and bpf_list_is_first/last(), allowing bpf_list_front/back()
results to be used as the insertion point, deletion target, or query
target for those kfuncs.
Verifier keeps existing owning-ref checks by default; only arguments
annotated with __nonown_allowed bypass MEM_ALLOC/ref_obj_id checks
and then follow the same list-node validation path.

ARM: zte: Add zx297520v3 platform support
This SoC is used in low end LTE-to-WiFi routers, for example some D-Link
DWR 932 revisions, ZTE K10, ZLT S10 4G, but also models that are branded
and sold by ISPs themselves. They are widespread in Africa, China,
Russia and Eastern Europe.
This SoC is a relative of the zx296702 and zx296718 that had some
upstream support until commit 89d4f98ae90d ("ARM: remove zte zx

The mdacon driver supports using ISA MDA or Hercules-compatible display
adapters as a secondary text console. This was commonly used in the
1990s and earlier for debugging software which took over the primary
display. It is highly unlikely anyone is doing so nowadays because
serial consoles and much better methods of debugging exist.
The driver is not enabled by any defconfig, nor any of the
dozens of distro configs collected at [1]. It has been relegated to VTs
13-16 since commit 0b9cf3aa6b1e ("mdacon messing up default vc's - set
default to vc13-16 again") in Linux 2.6.27 (and before Linux 2.5.53 -
see the link in the message of the above commit). The change in 2.6.27
was done because it was incorrectly detecting non-MDA adapters as MDA
and taking over all VTs, rendering them unusable.
Furthermore, vgacon supports using MDA/Hercules-compatible adapters as
the primary text console, so any systems with only one of these
adapters were already using vgacon and will not experience any loss in
functionality from the removal of this driver.
Given all of these factors, the mdacon driver is likely entirely
unused. Remove it.

vcn33_[12]_bt and vcn33_[12]_wifi refer to the same output. There are
two enable bits in the registers so that BT and WiFi drivers can toggle
them separately without any coordination. If either bit is set, then the
regulator output is enabled.
Deprecate the existing regulators, and add proper regulators matching
the outputs: vcn33_1 and vcn33_2.

The CSI2RX SHIM IP can support 32x DMA channels. These can be used to
split incoming "streams" of data on the CSI-RX port, distinguished by
MIPI Virtual Channel (or Data Type), into different locations in memory.
Actual number of DMA channels allocated to CSI-RX is dependent on the
usecase, and can be modified using the K3 Resource Partitioning tool [1].
So set the minimum channels as 1 and maximum as 32.

The i.MX95 CSI-2 controller is nearly identical to i.MX93, with the
main difference being the data output interface:
i.MX93 use IPI (Image Pixel Interface), which requires:
- Pixel clock input
- Software configuration through registers
i.MX95 uses IDI (Image Data Interface), which:
- Does not require pixel clock
- Is software transparent (no register configuration needed)
Due to these differences in register layout and initialization needs,
the two variants cannot share the same compatible string. The driver
needs to distinguish between them to handle the interface correctly.

Document the four known names of this device and the properties
that are sufficient for its use on the Nokia N8x0 tablet.
As I don't have this hardware or documentation for it, this is
purely based on existing usage in the driver.
