Some of these laptop models have quirk IDs that are identical but have
different amplifier parts fitted, this difference is described in the
ACPI information.
The solution introduced for this product family can derive the required
component binding information from ACPI instead of hardcoding it,
supports the new variants of the CS35L56 being used and has generalized
naming that makes it applicable to other ALC+amp combinations.

spi: Add empty versions of ACPI lookup functions
A patch from Richard Fitzgerald adding dummy versions of the ACPI lookup
functions for SPI:
Provide empty versions of acpi_spi_count_resources(),
acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
if the real functions are not being built.
This commit fixes two problems with the original definitions:
1) There wasn't an empty version of these functions
2) The #if only depended on CONFIG_ACPI. But the functions are implemented
in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
functions to exist.
On the tqma9352 the board is reset through an external PMIC, so
set the fsl,ext-reset-output property to enable triggering the
output pin on a watchdog trigger.

The L/R clock needs to be controlled by the SAI3 instead of the
CODEC to properly achieve stereo sound. Doing this allows removes
the need for unnecessary clock manipulation to try to get the

with a wide variety of clock inputs.

Pull x86 fixes from Thomas Gleixner:
- Fix 32-bit PTI for real.
pti_clone_entry_text() is called twice, once before initcalls so that
initcalls can use the user-mode helper and then again after text is
set read only. Setting read only on 32-bit might break up the PMD
mapping, which makes the second invocation of pti_clone_entry_text()
find the mappings out of sync and failing.
Allow the second call to split the existing PMDs in the user mapping
and synchronize with the kernel mapping.
- Don't make acpi_mp_wake_mailbox read-only after init as the mail box
must be writable in the case that CPU hotplug operations happen after
boot. Otherwise the attempt to start a CPU crashes with a write to
read only memory.
- Add a missing sanity check in mtrr_save_state() to ensure that the
fixed MTRR MSRs are supported.
Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
the WARN_ON() can bring systems down when panic on warn is set.

- Fix a couple of issues in the NTP code where user supplied values are

According to the history the sanity checks had been removed in favor
of clamping the values, but the clamping never worked correctly under
all circumstances. The NTP people asked to not bring the sanity
checks back as it might break existing applications.
Make the clamping work correctly and add it where it's missing
- If adjtimex() sets the clock it has to trigger the hrtimer subsystem
so it can adjust and if the clock was set into the future expire
timers if needed. The caller should provide a bitmask to tell
hrtimers which clocks have been adjusted.
adjtimex() uses not the proper constant and uses CLOCK_REALTIME
instead, which is 0. So hrtimers adjusts only the clocks, but does
not check for expired timers, which might make them expire really
late. Use the proper bitmask constant instead.

During Linux graceful reboot, the GPIO interrupts are not disabled.
Since the drivers are not removed during graceful reboot,
the logic to call mlxbf3_gpio_irq_disable() is not triggered.
Interrupts that remain enabled can cause issues on subsequent boots.
For example, the mlxbf-gige driver contains PHY logic to bring up the link.
If the gpio-mlxbf3 driver loads first, the mlxbf-gige driver
will use a GPIO interrupt to bring up the link.
Otherwise, it will use polling.
The next time Linux boots and loads the drivers in this order, we encounter the issue:
- mlxbf-gige loads first and uses polling while the GPIO10
interrupt is still enabled from the previous boot. So if
the interrupt triggers, there is nothing to clear it.
- gpio-mlxbf3 loads.
- i2c-mlxbf loads. The interrupt doesn't trigger for I2C
because it is shared with the GPIO interrupt line which
was not cleared.
The solution is to add a shutdown function to the GPIO driver to clear and disable
all interrupts. Also clear the interrupt after disabling it in mlxbf3_gpio_irq_disable().

The section 4.5.2 of the RISC-V AIA specification says that "any write
to a sourcecfg register of an APLIC might (or might not) cause the
corresponding interrupt-pending bit to be set to one if the rectified
input value is high (= 1) under the new source mode."
When the interrupt type is changed in the sourcecfg register, the APLIC
device might not set the corresponding pending bit, so the interrupt might
never become pending.
To handle sourcecfg register changes for level-triggered interrupts in MSI
mode, manually set the pending bit for retriggering interrupt so it gets
retriggered if it was already asserted.

The device tree property 'xlnx,kind-of-intr' is sanity checked that the
bitmask contains only set bits which are in the range of the number of

The check is done by shifting the mask right by the number of supported

The data type of the mask is u32 and the number of supported interrupts is
up to 32. In case of 32 interrupts the shift is out of bounds, resulting in
a mismatch warning. The out of bounds condition is also reported by UBSAN:

During latency tests (netperf TCP_RR) a 30% degradation of HW GRO vs SW
GRO was observed. This is due to SHAMPO triggering timeout filler CQEs
instead of delivering the CQE for the packet.
Having a short timeout for SHAMPO doesn't bring any benefits as it is
the driver that does the merging, not the hardware. On the contrary, it
can have a negative impact: additional filler CQEs are generated due to
the timeout. As there is no way to disable this timeout, this change
sets it to the maximum value.
Instead of using the packet_merge.timeout parameter which is also used
for LRO, set the value directly when filling in the rest of the SHAMPO
parameters in mlx5e_build_rq_param().

In commit 10154dbded ("udp: Allow GSO transmit from devices with no

CHECKSUM_NONE to pass to the GSO stack, so that they can be segmented and
checksummed by a software fallback when the egress device lacks these

What was not taken into consideration is that a CHECKSUM_NONE skb can be
handed over to the GSO stack also when the egress device advertises the
tx-udp-segmentation / NETIF_F_GSO_UDP_L4 feature.
This will happen when there are IPv6 extension headers present, which we
check for in __ip6_append_data(). Syzbot has discovered this scenario,

We are hitting the bad offload warning because when an egress device is
capable of handling segmentation offload requested by
skb_shinfo(skb)->gso_type, the chain of gso_segment callbacks won't produce
any segment skbs and return NULL. See the skb_gso_ok() branch in
{__udp,tcp,sctp}_gso_segment helpers.
To fix it, force a fallback to software USO when processing a packet with
IPv6 extension headers, since we don't know if these can checksummed by
all devices which offer USO.

UDP segmentation offload inherently depends on checksum offload. It should
not be possible to disable checksum offload while leaving USO enabled.
Enforce this dependency in code.
There is a single tx-udp-segmentation feature flag to indicate support for
both IPv4/6, hence the devices wishing to support USO must offer checksum
offload for both IP versions.

Commit 04d82a6d08 ("binfmt_flat: allow not offsetting data start")
introduced a RISC-V specific variant of the FLAT format which does
not allocate any space for the (obsolete) array of shared library
pointers. However, it did not disable the code which initializes the
array, resulting in the corruption of sizeof(long) bytes before the DATA
segment, generally the end of the TEXT segment.
Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of
CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of
the shared library pointer region so that it will only be initialized
if space is reserved for it.

bcachefs_metadata_version_disk_accounting_v2 erroneously had padding
bytes in disk_accounting_key, which is a problem because we have to
guarantee that all unused bytes in disk_accounting_key are zeroed.
Fortunately 6.11 isn't out yet, so it's cheap to fix this by spinning a
new version.

cxl_test module models a CXL topology for testing, it creates some
emulated dports with platform devices in the CXL topology, so the
dport_dev of an emulated dport points to a platform device rather than a
pci device or a pci host bridge in the case. Currently,
cxl_setup_parent_dport() is used to set up RAS and AER capability on the
dport connected to the CXL memory device, but cxl_test does not support
RAS or AER functionality yet, so the fix is implementing a
__wrap_cxl_setup_parent_dport() to filter out all emulated dports,
guarantees only real dports can be handled by cxl_setup_parent_dport().

LLVM 19 is dropping support for 3DNow! in commit f0eb5587ceeb ("Remove
support for 3DNow!, both intrinsics and builtins. (#96246)"):
Remove support for 3DNow!, both intrinsics and builtins. (#96246)
This set of instructions was only supported by AMD chips starting in
the K6-2 (introduced 1998), and before the "Bulldozer" family
(2011). They were never much used, as they were effectively superseded
by the more-widely-implemented SSE (first implemented on the AMD side
in Athlon XP in 2001).
This is being done as a predecessor towards general removal of MMX
register usage. Since there is almost no usage of the 3DNow!
intrinsics, and no modern hardware even implements them, simple
removal seems like the best option.
Thus we should avoid passing these to the backend, since otherwise we
get a diagnostic about it:
'-3dnow' is not a recognized feature for this target (ignoring feature)
'-3dnowa' is not a recognized feature for this target (ignoring feature)
We could try to disable them only up to LLVM 19 (not the C side one,
but the one used by `rustc`, which may be built with a range of
LLVMs). However, to avoid more complexity, we can likely just remove
them altogether. According to Nikita [2]:
> I don't think it's needed because LLVM should not generate 3dnow
> instructions unless specifically asked to, using intrinsics that
> Rust does not provide in the first place.
Thus do so, like Rust did for one of their builtin targets [3].
For those curious: Clang will warn only about trying to enable them
(`-m3dnow{,a}`), but not about disabling them (`-mno-3dnow{,a}`), so
there is no change needed there.

When calling the `rust_is_available.sh` script, we need to make the
jobserver available to it, as commit ecab4115c4 ("kbuild: mark `rustc`
(and others) invocations as recursive") explains and did for the others.
Otherwise, we get a warning from `rustc` when calling `make rust-analyzer`
with parallel jobs, e.g. `-j8`. Using several jobs for that target does
not really matter, but developers may call `make` with jobs enabled in
all cases.
Thus fix it.

Alice reported [1] that an arm64 build failed with:
ld.lld: error: undefined symbol: __extendsfdf2

Rust 1.80.0 or later together with `CONFIG_CC_OPTIMIZE_FOR_SIZE=y`
is what triggers it.
In addition, x86_64 builds also fail the same way.
Similarly, compiling with Rust 1.82.0 (currently in nightly) makes
another one appear, possibly due to the LLVM 19 upgrade there:
ld.lld: error: undefined symbol: __eqdf2
>>> referenced by core.20495ea57a9f069d-cgu.0

>>> referenced by core.20495ea57a9f069d-cgu.0
>>> rust/core.o:(<f64>::next_down) in archive vmlinux.a
Gary adds [1]:
> Usually the fix on rustc side is to mark those functions as `#[inline]`
>

> marked as inline...
Fix all those by adding those intrinsics to our usual workaround.
[ Trevor quickly submitted a fix to upstream Rust [2] that has already
been merged, to be released in Rust 1.82.0 (2024-10-17). - Miguel ]
