4598380f9c bonding: fix ns validation on backup slaves
When arp_validate is set to 2, 3, or 6, validation is performed for
backup slaves as well. As stated in the bond documentation, validation
involves checking the broadcast ARP request sent out via the active
slave. This helps determine which slaves are more likely to function in
the event of an active slave failure.

However, when the target is an IPv6 address, the NS message sent from
the active interface is not checked on backup slaves. Additionally,
based on the bond_arp_rcv() rule b, we must reverse the saddr and daddr
when checking the NS message.

Note that when checking the NS message, the destination address is a
multicast address. Therefore, we must convert the target address to
solicited multicast in the bond_get_targets_ip6() function.

Prior to the fix, the backup slaves had a mii status of "down", but
after the fix, all of the slaves' mii status was updated to "UP".

05f3ab7780 net: ethernet: mtk_eth_soc: add code for offloading flows from wlan devices
WED version 2 (on MT7986 and later) can offload flows originating from
wireless devices.
In order to make that work, ndo_setup_tc needs to be implemented on the
netdevs. This adds the required code to offload flows coming in from WED,
while keeping track of the incoming wed index used for selecting the
correct PPE device.

dma_default_coherent was decleared unconditionally at kernel/dma/mapping.c

dma-map-ops.h.

Guard the declaration in mapping.c with non-coherent options and provide
a fallback definition.

8751d15426 io_uring: reduce scheduling due to tw
Every task_work will try to wake the task to be executed, which causes
excessive scheduling and additional overhead. For some tw it's
justified, but others won't do much but post a single CQE.

When a task waits for multiple cqes, every such task_work will wake it
up. Instead, the task may give a hint about how many cqes it waits for,
io_req_local_work_add() will compare against it and skip wake ups
if #cqes + #tw is not enough to satisfy the waiting condition. Task_work
that uses the optimisation should be simple enough and never post more
than one CQE. It's also ignored for non DEFER_TASKRUN rings.

least one interrupt, so use a union to keep space allocated for this.

The only binary change in .text and .data sections is some rearrangement
by the compiler of acpi_dm_address_common(), but appears to be harmless.

The "Source" array is actually a dynamically sized array, but it

both compile-time and run-time bounds checkers (e.g. via either
__builtin_object_size() or -fsanitize=bounds).

To retain the padding, create a union with an unused Pad variable of

11132ad017 ACPICA: Introduce ACPI_FLEX_ARRAY
ACPICA commit e73b227e8e475c20cc394f237ea35d592fdf9ec3

In order to enable using -fstrict-flex-arrays with GCC and Clang in the
Linux kernel, each trailing dynamically sized array must be defined as
proper C99 "flexible array members" (FAM). Unfortunately, ACPICA has a
bunch of technical debt, dating back to before even the GNU extension of
0-length arrays, meaning the code base has many 1-element and 0-length
arrays defined at the end of structures that should actually be FAMs.

One limitation of the C99 FAM specification is the accidental requirement
that they cannot be in unions or alone in structs. There is no real-world
reason for this, though, and, actually, the existing GNU extension
permits this for 0-length arrays (which get treated as FAMs).

Add the ACPI_FLEX_ARRAY() helper macro to work around this requirement
so that FAMs can be defined in unions or alone in structs. Since this
behavior still depends on GNU extensions, keep the macro specific to GCC
(and Clang) builds. In this way, MSVC will continue to use 0-length
arrays (since it does not support the union work-around). When MSVC
grows support for this in the future, the macro can be updated.

Unlike struct acpi_nfit_flush_address and struct acpi_nfit_smbios, which
had their sizeof() uses adjusted in code, struct acpi_nfit_interleave did
not. This appears to have been a bug. After this change, there is a binary
difference in acpi_dm_dump_nfit() since the size of the structure now has
the correct size, as the prior result was including the trailing U32:

-       mov    $0x14,%ebp

ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53

Like many tables, this is a header followed by multiple subtables of
varying self-identifying types, and ACPICA does not normally add a field
for the subtables, instead relying on pointer arithmetic past the end of
the first header struct, since indexing a flexible array member is
meaningless for variable-length entries. If we really wanted a field for
this, we could use a u8 flexible array member, but it contradicts the
current style. Using void *, however, is categorically wrong, as ACPI
tables never contain native C-language pointers.

This particular combination of flags is used by most filesystems
in their ->write_begin method, although it does find use in a
few other places.  Before folios, it warranted its own function
(grab_cache_page_write_begin()), but I think that just having specialised

d769ccaf95 xsk: Fix unaligned descriptor validation
Make sure unaligned descriptors that straddle the end of the UMEM are
considered invalid. Currently, descriptor validation is broken for
zero-copy mode which only checks descriptors at page granularity.
For example, descriptors in zero-copy mode that overrun the end of the
UMEM but not a page boundary are (incorrectly) considered valid. The
UMEM boundary check needs to happen before the page boundary and
contiguity checks in xp_desc_crosses_non_contig_pg(). Do this check in
xp_unaligned_validate_desc() instead like xp_check_unaligned() already
does.

ASoC: SOF: Intel: hda-mlink: program SoundWire LSDIID registers
Each SoundWire peripheral can be programmed from the manager side
either with a regular command FIFO, or with the HDaudio CORB/RIRB
DMA-based mechanism. The mapping between SoundWire peripheral and SDI
address is handled with the LSDIID register.

This mapping only works of course if each peripheral has a unique
address across all links. This has already been enforced in previous
Intel contributions allowing for an IDA-based solution for the device
number allocation.

The checks on the dev_num are handled at the SoundWire level, but the
locking is handled at the hda-mlink level.

These helpers configure the ratio between the base clock and the
hardware signal used for link synchronization.

The SYNCPRD is written before the first sublink is powered-up. The
SYNCPU bit is set, but it will only be cleared after the link is
powered-up, hence the implementation with a set/wait pattern.

These helpers are currently only needed by SoundWire support, where
the lock is taken at a higher level, so only the _unlocked versions
are exposed for now.

Note that the _wait_bit() implementation is similar to previous
helpers in drivers/soundwire, but with sleep duration and timeout
aligned with hardware recommendations. If desired, this helper could
be modified in a second step with e.g. readl_poll_timeout().

ASoC: SOF: Intel: hda-mlink: add convenience helpers for SoundWire PM
The updated SoundWire Intel driver will need to rely on Extended
HDaudio links for power management, but it doesn't need to be aware of
all the HDaudio structures. Add convenience helpers to avoid polluting
SoundWire drivers too much with HDaudio information.

Since the SoundWire/Intel solution already takes the lock at a higher
level, the _unlocked PM helpers are used.

ASoC: SOF: Intel: hda-mlink: introduce helpers for 'extended links' PM
Add helpers to program SPA/CPA bits, using a mutex to access the
shared LCTL register if required.

All links are managed with the same LCTLx.SPA bits. However there are
quite a few implementation details to be aware of:

Legacy HDaudio multi-links are powered-up when exiting reset, which
requires the ref_count to be manually set to one when initializing the
link.

Alternate links for SoundWire/DMIC/SSP need to be explicitly
powered-up before accessing the SHIM/IP/Vendor-Specific SHIM space for
each sublink. DMIC/SSP/SoundWire are all different cases with a
different device/dai/hlink relationship.

SoundWire will handle power management with the auxiliary device
resume/suspend routine. The ref_count is not necessary in this case.

The DMIC/SSP will by contrast handle the power management from DAI
.startup and .shutdown callbacks.

The SSP has a 1:1 mapping between sublink and DAI, but it's
bidirectional so the ref_count will help avoid turning off the sublink
when one of the two directions is still in use.

The DMIC has a single link but two DAIs for data generated at
different sampling frequencies, again the ref_count will make sure the
two DAIs can be used concurrently.

And last the SoundWire Intel require power-up/down and bank switch to
be handled with a lock already taken, so the 'eml_lock' is made
optional with the _unlocked versions of the helpers.

Note that the _check_power_active() implementation is similar to
previous helpers in sound/hda/ext, with sleep duration and timeout
aligned with hardware recommendations. If desired, this helper could
be modified in a second step with .e.g. readl_poll_timeout()

ASoC: SOF: Intel: hda-mlink: add structures to parse ALT links
Extend hdac_ext_link to store information needed for ALT
links. Follow-up patches will include more functional patches for
power-up and down.

Note that this patch suggests the use of an 'eml_lock' to serialize
access to shared registers. SoundWire-specific sequence require the
lock to be taken at a higher level, as a result the helpers added in
follow-up patches will provide 'unlocked' versions when needed.

Also note that the low-level sequences with the 'hdaml_' prefix are
taken directly from the hardware specifications - naming conventions
included. The code will be split in two, with locking and linked-list
management handled separately to avoid mixing required hardware setup
and Linux-based resource management.
