After commit 8cc71fc3b8 ("wifi: cfg80211: Fix "no buffer
space available" error in nl80211_get_station() for MLO"),
the per-link data is only included in station dumps, where
the size limit is somewhat less of an issue. However, it's
still an issue, depending on how many links a station has
and how much per-link data there is. Thus, for now, disable
per-link statistics entirely.
A complete fix will need to take this into account, make it
opt-in by userspace, and change the dump format to be able
to split a single station's data across multiple netlink
dump messages, which all together is too much development
for a fix.

The iMON driver improperly releases the usb_device reference in
imon_disconnect without coordinating with active users of the
device.
Specifically, the fields usbdev_intf0 and usbdev_intf1 are not
protected by the users counter (ictx->users). During probe,
imon_init_intf0 or imon_init_intf1 increments the usb_device
reference count depending on the interface. However, during
disconnect, usb_put_dev is called unconditionally, regardless of
actual usage.
As a result, if vfd_write or other operations are still in
progress after disconnect, this can lead to a use-after-free of
the usb_device pointer.

Guard access to usbdev_intf0 and usbdev_intf1 after disconnect by
checking ictx->disconnected in all writer paths. Add early return
with -ENODEV in send_packet(), vfd_write(), lcd_write() and
display_open() if the device is no longer present.
Set and read ictx->disconnected under ictx->lock to ensure memory
synchronization. Acquire the lock in imon_disconnect() before setting
the flag to synchronize with any ongoing operations.
Ensure writers exit early and safely after disconnect before the USB
core proceeds with cleanup.

The driver inserts a VLAN header into RoCE packets when the
traffic was untagged by modifying the existing GID entries.
This has caused the firmware to enforce only VLAN-based
priority mappings, ignoring other valid priority configurations
set via APP TLVs (e.g., DSCP selectors).
Driver now has support for selecting the service level (vlan id)
and traffic class (dscp) during modify_qp. So no need to override
the priority update using the update gid method. Hence removing
the code that handles the above operation.

In bnxt_re_register_ib(), strscpy() is called with the length of the
source string rather than the size of the destination buffer.
This is fine as long as the destination buffer is larger than the source
string, but we should still use the destination buffer size instead to
call strscpy() as intended. And since 'node_desc' has a fixed size, we
can safely omit the size argument and let strscpy() infer it using
sizeof().

When using KSM (Key Scatter-gather Memory) access mode, the HW requires
the IOVA to be aligned to the selected page size.
Without this alignment, the HW may not function correctly.
Currently, mlx5_umem_mkc_find_best_pgsz() does not filter out page sizes
that would result in misaligned IOVAs for KSM mode. This can lead to
selecting page sizes that are incompatible with the given IOVA.
Fix this by filtering the page size bitmap when in KSM mode, keeping
only page sizes to which the IOVA is aligned to.

Pull vmescape mitigation fixes from Dave Hansen:
"Mitigate vmscape issue with indirect branch predictor flushes.
vmscape is a vulnerability that essentially takes Spectre-v2 and
attacks host userspace from a guest. It particularly affects
hypervisors like QEMU.
Even if a hypervisor may not have any sensitive data like disk
encryption keys, guest-userspace may be able to attack the
guest-kernel using the hypervisor as a confused deputy.
There are many ways to mitigate vmscape using the existing Spectre-v2
defenses like IBRS variants or the IBPB flushes. This series focuses
solely on IBPB because it works universally across vendors and all
vulnerable processors. Further work doing vendor and model-specific
optimizations can build on top of this if needed / wanted.
Do the normal issue mitigation dance:
- Add the CPU bug boilerplate
- Add a list of vulnerable CPUs
- Use IBPB to flush the branch predictors after running guests"

FEC WoL (Wake-on-Lan) functionality depends on using Ethernet PHY in IRQ
mode. However, on phyCORE-i.MX93 SoM, polling mode is used instead for
the FEC Ethernet PHY. Consequently, WoL is non-functional. Thus disable
it by removing "fsl,magic-packet" property. This allows us to save some
power during device suspend as PHY is not kept awake.

'dma-name' is not a valid property and causes the following dt-schema
warning:
dma-name: b'rx\x00tx\x00' is not of type 'object', 'integer', 'array', 'boolean', 'null'
Fix it by using 'dma-names' instead.

Commit 21179eae56 ("arm64: dts: freescale: imx93-phyboard-nash: Add
current sense amplifier") added information about the current sensing
circuitry found on the board. Now, lets provide current sense reading
also via IIO-hwmon subsystem. This way, SoM current can be read directly
via sysfs property more conveniently for the customers. No need for them
to manually apply scaling factor calculations anymore.

The TMU has two temperature measurement sites located on the chip. The
probe 0 is located inside of the ANAMIX, while the probe 1 is located near
the ARM core. This has been confirmed by checking with HW design team and
checking RTL code.
So correct the {cpu,soc}-thermal sensor index.
