====================
net: header and core spelling corrections
This patchset addresses a number of spelling errors in comments in
Networking files under include/, and files in net/core/. Spelling
problems are as flagged by codespell.
It aims to provide patches that can be accepted directly into net-next.
And splits patches up based on maintainer boundaries: many things
feed directly into net-next. This is a complex process and I apologise
for any errors.
I also plan to address, via separate patches, spelling errors in other
files in the same directories, for files whose changes typically go
through trees other than net-next (which feed into net-next).

Add support for dumping PA stats registers via ethtool.
Firmware maintained stats are stored at PA Stats registers.
Also modify emac_get_strings() API to use ethtool_puts().
This commit also maintains consistency between miig_stats and pa_stats by
- renaming the array icssg_all_stats to icssg_all_miig_stats
- renaming the structure icssg_stats to icssg_miig_stats
- renaming ICSSG_STATS() to ICSSG_MIIG_STATS()
- changing order of stats related data structures and arrays so that data
structures of a certain stats type is clubbed together.

The ice_sq_done function is used to check the control queue head register
and determine whether or not the control queue processing is done. This
function is called in a loop checking against jiffies for a specified
timeout.
The pattern of reading a register in a loop until a condition is true or a
timeout is reached is a relatively common pattern. In fact, the kernel
provides a read_poll_timeout function implementing this behavior in
<linux/iopoll.h>
Use of read_poll_timeout is preferred over directly coding these loops.
However, using it in the ice driver is a bit more difficult because of the
rd32 wrapper. Implement a rd32_poll_timeout wrapper based on
read_poll_timeout.
Refactor ice_sq_done to use rd32_poll_timeout, replacing the loop calling
ice_sq_done in ice_sq_send_cmd. This simplifies the logic down to a single
ice_sq_done() call.
The implementation of rd32_poll_timeout uses microseconds for its timeout
value, so update the CQ timeout macros used to be specified in microseconds
units as well instead of using HZ for jiffies.

====================
Add ALCD Support to Cable Testing Interface
This patch series introduces support for Active Link Cable Diagnostics
(ALCD) in the ethtool cable testing interface and the DP83TD510 PHY
driver.
Why ALCD?
On a 10BaseT1L interface, TDR (Time Domain Reflectometry) is not
possible if the link partner is active - TDR will fail in these cases
because it requires interrupting the link. Since the link is active, we
already know the cable is functioning, so instead of using TDR, we can
use ALCD.
ALCD lets us measure cable length without disrupting the active link,
which is crucial in environments where network uptime is important. It
provides a way to gather diagnostic data without the need for downtime.
What's in this series:
- Extended the ethtool cable testing interface to specify the source of
diagnostic results (TDR or ALCD).
- Updated the DP83TD510 PHY driver to use ALCD when the link is
active, ensuring we can still get cable length info without dropping the
connection.

In industrial environments where 10BaseT1L PHYs are replacing existing
field bus systems like CAN, it's often essential to retain the existing
cable infrastructure. After installation, collecting metrics such as
cable length is crucial for assessing the quality of the infrastructure.
Traditionally, TDR (Time Domain Reflectometry) is used for this purpose.
However, TDR requires interrupting the link, and if the link partner
remains active, the TDR measurement will fail.
Unlike multi-pair systems, where TDR can be attempted during the MDI-X
switching window, 10BaseT1L systems face greater challenges. The TDR
sequence on 10BaseT1L is longer and coincides with uninterrupted
autonegotiation pulses, making TDR impossible when the link partner is
active.
The DP83TD510 PHY provides an alternative through ALCD (Active Link
Cable Diagnostics), which allows for cable length measurement without
disrupting an active link. Since a live link indicates no short or open
cable states, ALCD can be used effectively to gather cable length
information.
Enhance the dp83td510 driver by:
- Leveraging ALCD to measure cable length when the link is active.
- Bypassing TDR when a link is detected, as ALCD provides the required
information without disruption.

Enhance the ethtool cable test interface by introducing the ability to
specify the source of the diagnostic information for cable test results.
This is particularly useful for PHYs that offer multiple diagnostic
methods, such as Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD).
Key changes:
- Added `ethnl_cable_test_result_with_src` and
`ethnl_cable_test_fault_length_with_src` functions to allow specifying
the information source when reporting cable test results.
- Updated existing `ethnl_cable_test_result` and
`ethnl_cable_test_fault_length` functions to use TDR as the default
source, ensuring backward compatibility.
- Modified the UAPI to support these new attributes, enabling drivers to
provide more detailed diagnostic information.

Extend the ethtool netlink cable testing interface by adding support for
specifying the source of cable testing results. This allows users to
differentiate between results obtained through different diagnostic
methods.
For example, some TI 10BaseT1L PHYs provide two variants of cable
diagnostics: Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD). By introducing `ETHTOOL_A_CABLE_RESULT_SRC` and
`ETHTOOL_A_CABLE_FAULT_LENGTH_SRC` attributes, this update enables
drivers to indicate whether the result was derived from TDR or ALCD,
improving the clarity and utility of diagnostic information.

Adds a selftest that creates two virtual interfaces, assigns one to a
new namespace, and assigns IP addresses to both.
It listens on the destination interface using socat and configures a
dynamic target on netconsole, pointing to the destination IP address.
The test then checks if the message was received properly on the
destination interface.

====================
netconsole: Populate dynamic entry even if netpoll fails
The current implementation of netconsole removes the entry and fails
entirely if netpoll fails to initialize. This approach is suboptimal, as
it prevents reconfiguration or re-enabling of the target through
configfs.
While this issue might seem minor if it were rare, it actually occurs
frequently when the network module is configured as a loadable module.
In such cases, the network is unavailable when netconsole initializes,
causing netpoll to fail. This failure forces users to reconfigure the
target from scratch, discarding any settings provided via the command
line.
The proposed change would keep the target available in configfs, albeit
in a disabled state. This modification allows users to adjust settings
or simply re-enable the target once the network module has loaded,
providing a more flexible and user-friendly solution.

Currently, netconsole discards targets that fail during initialization,
causing two issues:
1) Inconsistency between target list and configfs entries
* user pass cmdline0, cmdline1. If cmdline0 fails, then cmdline1
becomes cmdline0 in configfs.
2) Inability to manage failed targets from userspace
* If user pass a target that fails with netpoll (interface not loaded at
netcons initialization time, such as interface is a module), then
the target will not exist in the configfs, so, user cannot re-enable
or modify it from userspace.
Failed targets are now added to the target list and configfs, but
remain disabled until manually enabled or reconfigured. This change does
not change the behaviour if CONFIG_NETCONSOLE_DYNAMIC is not set.

Modify netpoll_setup() and __netpoll_setup() to ensure that the netpoll
structure (np) is left in a clean state if setup fails for any reason.
This prevents carrying over misconfigured fields in case of partial
setup success.
Key changes:
- np->dev is now set only after successful setup, ensuring it's always
NULL if netpoll is not configured or if netpoll_setup() fails.
- np->local_ip is zeroed if netpoll setup doesn't complete successfully.
- Added DEBUG_NET_WARN_ON_ONCE() checks to catch unexpected states.
- Reordered some operations in __netpoll_setup() for better logical flow.
These changes improve the reliability of netpoll configuration, since it
assures that the structure is fully initialized or totally unset.

There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.
Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.

MLO internal scan may include 6 GHz channels. Since the 6 GHz scan
indication is not set, the channel flags are set incorrectly, which
leads to a firmware assert.
Since the MLO scan may include 6 GHz and non 6 GHz channels in one
request, add support for non-PSC 6 GHz channels (PSC channels are
already supported) when the 6 GHz indication is not set.

Check size of WGDS revision 3 is equal to 8 entries size with some header,
but doesn't depend on the number of used entries. Check that used entries
are between min and max but allow more to be present than are used to fix
operation with some BIOSes that have such data.

iwl_mvm_select_links is called by the link selection worker and it
requires the mutex.
Take it in the link selection worker.
This logic used to run from iwl_mvm_rx_umac_scan_complete_notif which
had the mvm->mutex held. This was changed to run in a worker holding the
wiphy mutex, but we also need the mvm->mutex.

Fast resume is a feature that was recently introduced to speed up the
resume time. It basically keeps the firmware alive while the system
is suspended and that avoids starting again the whole device.
This flow can't work for hibernation, since when the system boots,
before the frozen image is loaded, the kernel may touch the device. As a
result, we can't assume the device is in the exact same state as before
the hibernation.
Detect that we are resuming from hibernation through the PCI device and
forbid the fast resume flow. We also need to shut down the device
cleanly when that happens.
In addition, in case the device is power gated during S3, we won't be
able to keep the device alive. Detect this situation with BE200 at least
with the help of the CSR_FUNC_SCRATCH register and reset the device upon
resume if it was power gated during S3.

If ParaVirt steal time feature is enabled, there is a percpu gpa address
passed from guest vCPU and host modifies guest memory space with this gpa
address. When vCPU is reset normally, it will notify host and invalidate
gpa address.
However if VM is crashed and VMM reboots VM forcely, the vCPU reboot
notification callback will not be called in VM. Host needs invalidate
the gpa address, else host will modify guest memory during VM reboots.
Here it is invalidated from the vCPU KVM_REG_LOONGARCH_VCPU_RESET ioctl
interface.
Also funciton kvm_reset_timer() is removed at vCPU reset stage, since SW
emulated timer is only used in vCPU block state. When a vCPU is removed
from the block waiting queue, kvm_restore_timer() is called and SW timer
is cancelled. And the timer register is also cleared at VMM when a vCPU
is reset.

There exist some warnings when building kernel if CONFIG_CPU_HAS_LBT is
set but CONFIG_CPU_HAS_LSX and CONFIG_CPU_HAS_LASX are not set. In this
case, there are no definitions of _restore_lsx & _restore_lasx and there
are also no definitions of kvm_restore_lsx & kvm_restore_lasx in fpu.S
and switch.S respectively, just add some ifdefs to fix these warnings.

Currently we call irq_set_noprobe() in a loop for all IRQs, but indeed
it only works for IRQs below NR_IRQS_LEGACY because at init_IRQ() only
legacy interrupts have been allocated.
Instead, we can define ARCH_IRQ_INIT_FLAGS as IRQ_NOPROBE in asm/hwirq.h
and the core will automatically set the flag for all interrupts.

extent_fiemap()
There's a warning (probably on some older compiler version):
fs/btrfs/fiemap.c: warning: 'last_extent_end' may be used uninitialized in this function [-Wmaybe-uninitialized]: => 822:19
Initialize the variable to 0 although it's not necessary as it's either
properly set or not used after an error. The called function is in the
same file so this is a false alert but we want to fix all
-Wmaybe-uninitialized reports.
