All callers pass PHY_POLL, therefore remove irq argument from
fixed_phy_register().
Note: I keep the irq argument in fixed_phy_add_gpiod() for now,
for the case that somebody may want to use a GPIO interrupt in
the future, by e.g. adding a call to fwnode_irq_get() to
fixed_phy_get_gpiod().

Cover three recent cases:
1. missing ops locking for the lowers during netdev_sync_lower_features
2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked
with a comment on why/when it's needed)
3. rcu lock during team_change_rx_flags
Verified that each one triggers when the respective fix is reverted.
Not sure about the placement, but since it all relies on teaming,
added to the teaming directory.
One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way
to trigger netdev_sync_lower_features without it.

The current implementation of per-pdev frequency range updates assumes that
each pdev supports only a single band. As a result in ath12k_regd_update(),
bands are handled using an if-else structure, which limits updates to only
one of the band per pdev. This assumption does not hold for all chipsets.
For example, the WCN7850 supports multiple bands within a single pdev.
Hence to accommodate such cases, update the logic to account for all band
cases by handling each band in a separate if conditions instead of the
previous if-else structure.

Commit 3ef9f710efcb ("pinctrl: mediatek: Add EINT support for multiple
addresses") introduced an access to the 'soc' field of struct
mtk_pinctrl in mtk_eint_do_init() and for that an include of
pinctrl-mtk-common-v2.h.
However, pinctrl drivers relying on the v1 common driver include
pinctrl-mtk-common.h instead, which provides another definition of
struct mtk_pinctrl that does not contain an 'soc' field.
Since mtk_eint_do_init() can be called both by v1 and v2 drivers, it
will now try to dereference an invalid pointer when called on v1
platforms. This has been observed on Genio 350 EVK (MT8365), which
crashes very early in boot (the kernel trace can only be seen with
earlycon).
In order to fix this, since 'struct mtk_pinctrl' was only needed to get
a 'struct mtk_eint_pin', make 'struct mtk_eint_pin' a parameter
of mtk_eint_do_init() so that callers need to supply it, removing
mtk_eint_do_init()'s dependency on any particular 'struct mtk_pinctrl'.

On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request()
calls gpiochip_line_is_valid(). After commit 8015443e24e7 ("gpio: Hide
valid_mask from direct assignments") gpiochip_line_is_valid() uses
gc->gpiodev, which is NULL when GPIO hog pins are being processed.
Thus after this commit using GPIO hogs causes the following crash. In
order to fix this, verify that gc->gpiodev is not NULL.
Note: it is not possible to reorder calls (e.g. by calling
msm_gpio_init() before pinctrl registration or by splitting
pinctrl_register() into _and_init() and pinctrl_enable() and calling the
latter function after msm_gpio_init()) because GPIO chip registration
would fail with EPROBE_DEFER if pinctrl is not enabled at the time of
registration.

Going bus-off on a channel doing RX could result in dropped packets.
As netif_running() gets cleared before the channel abort procedure,
the handling of any last RDATA packets would see netif_rx() return
non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt
with this "error" by breaking out of processing the remaining DMA RX
buffer.
Only return an error from kvaser_pciefd_read_buffer() due to packet
corruption, otherwise handle it internally.

The functions kvaser_pciefd_start_xmit() and
kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and
get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken
when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented
prior to handling of ACKs. E.g., this caused the following error:
can_put_echo_skb: BUG! echo_skb 5 is occupied!
Instead, use the synchronization helpers in netdev_queues.h. As those
piggyback on BQL barriers, start updating in-flight packets and bytes
counts as well.

UBLK_F_AUTO_BUF_REG
Add UBLK_F_AUTO_BUF_REG for supporting to register buffer automatically
to local io_uring context with provided buffer index.
Add UAPI structure `struct ublk_auto_buf_reg` for holding user parameter
to register request buffer automatically, one 'flags' field is defined, and
there is still 32bit available for future extension, such as, adding one
io_ring FD field for registering buffer to external io_uring.
`struct ublk_auto_buf_reg` is populated from ublk uring_cmd's sqe->addr,
and all existing ublk commands are data-less, so it is just fine to reuse
sqe->addr for this purpose.

UBLK_F_SUPPORT_ZERO_COPY requires ublk server to issue explicit buffer
register/unregister uring_cmd for each IO, this way is not only inefficient,
but also introduce dependency between buffer consumer and buffer register/
unregister uring_cmd, please see tools/testing/selftests/ublk/stripe.c
in which backing file IO has to be issued one by one by IOSQE_IO_LINK.
Prepare for adding feature UBLK_F_AUTO_BUF_REG for addressing the existing
zero copy limitation:
- register request buffer automatically to ublk uring_cmd's io_uring
context before delivering io command to ublk server
- unregister request buffer automatically from the ublk uring_cmd's
io_uring context when completing the request
- io_uring will unregister the buffer automatically when uring is
exiting, so we needn't worry about accident exit
For using this feature, ublk server has to create one sparse buffer table

Whenever there is a change in the country code settings from the
user, driver does an intersection of the regulatory rules for this
new country with the original regulatory rules which were reported
during initialization time.
There is also similar logic running in firmware with a difference
that the intersection in firmware is only done when the country code
is configuration during boot up time (BDF/OTP). Firmware logic does
not kick in when no country code is configured during device bring
up time as the device is always expected to have the country code
configured properly in the deployment.
There is a debug/test use case that requires absolute regulatory
rules to be used for a user configured country code when the device
is not configured with a particular country code during boot up time.
To support the above test use case, remove the redundant regulatory
rules intersection logic in the host driver. Depend on the
intersection logic in firmware when the device comes up with
pre-configured country code.

As per IEEE 802.11be-2024 - 9.4.2.321, EHT operation element
contains MCS15 Disable subfield as the sixth bit, which is set when
MCS15 support is not enabled.
During association, firmware will use this MCS15 flag to enable or
disable the reception of PPDU with EHT-MCS15 capability.
Send MCS15 support to firmware through WMI command during peer assoc.

Change the creation of mkey to be performed in multiple steps:
data allocation, DMA setup and actual call to HW to create that mkey.
In this new flow, the whole input to MKEY command is saved to eliminate
the need to keep array of pointers for DMA addresses for receive list
and in the future patches for send list too.
In addition to memory size reduce and elimination of unnecessary data
movements to set MKEY input, the code is prepared for future reuse.

allocated_length is a multiple of page size and number of pages,
so let's change the functions to accept number of pages. This improves
code readability, simplifies buffer handling, and enables combining DMA
send/receive operations, as will be introduced in the next patches.

In situations where mapping/unmapping sequence can be controlled by
userspace, attempting to map over a region that has not yet been
unmapped is an error. But not something that should spam dmesg.
Now that there is a quirk, we can also drop the selftest_running
flag, and use the quirk instead for selftests.

After having factored out the provider part from mdio_bus.c, we can
make the mdio consumer / device layer a separate module. This also
allows to remove Kconfig symbol MDIO_DEVICE.
The module init / exit functions from mdio_bus.c no longer have to be
called from phy_device.c. The link order defined in
drivers/net/phy/Makefile ensures that init / exit functions are called
in the right order.

A few, quite rare, WMI attributes have names that are not compatible with
filenames, e.g. "Intel VT for Directed I/O (VT-d)".
For these cases the '/' gets replaced with '\' for display, but doesn't
get switched again when doing the WMI access.
Fix this by keeping the original attribute name and using that for sending
commands to the BIOS

Merge series from Geert Uytterhoeven <geert+renesas@glider.be>:
This patch series (A) improves single transfer sizes in the MSIOF
driver, using two methods:
- By increasing the assumed FIFO sizes, impacting both PIO and DMA
transfers,
- By using two groups, impacting DMA transfers,
and (B) lets the recently-introduced MSIOF I2S drive reuse the SPI
driver's register definitions. All of this is covered with a thick
sauce of fixes for (harmless) bugs, cleanups, and refactorings.
Note that the driver uses the limitations as specified in the hardware
documentation. For discovering the actual FIFO sizes, I wrote some
crude test code that can be found at [2].
This is based on spi/for-next and sound-asoc/for-next, and has been
tested on a variery of R-Car SoCs.

If either REGMAP_IRQ or REGMAP_MDIO are set then REGMAP is also set.
This then enables the selecting of IRQ_DOMAIN or MDIO_BUS from REGMAP
based on the above two symbols respectively. This makes it very easy
to end up with "circular dependencies".
Instead select the IRQ_DOMAIN or MDIO_BUS from the symbols that make
use of them. This is almost equivalent to before but makes it less
likely to end up with false circular dependency detections.

Currently, all SCMI devices with performance domains attempt to register
a cpufreq driver, even if their performance domains aren't used to
control the CPUs. The cpufreq framework only supports registering a
single driver, so only the first device will succeed. And if that device
isn't used for the CPUs, then cpufreq will scale the wrong domains.
To avoid this, return early from scmi_cpufreq_probe() if the probing
SCMI device isn't referenced by the CPU device phandles.
This keeps the existing assumption that all CPUs are controlled by a
single SCMI device.

In the NVMe context, the term "shutdown" has a specific technical
meaning. To avoid confusion, this commit renames the nvme_mpath_
shutdown_disk function to nvme_mpath_remove_disk to better reflect
its purpose (i.e. removing the disk from the system). However,
nvme_mpath_remove_disk was already in use, and its functionality
is related to releasing or putting the head node disk. To resolve
this naming conflict and improve clarity, the existing nvme_mpath_
remove_disk function is also renamed to nvme_mpath_put_disk.
This renaming improves code readability and better aligns function
names with their actual roles.
