Hi,
A recent attempt to fix a missing symbol when
CONFIG_SND_SOC_SDCA=m and CONFIG_SND_SOC_ACPI_INTEL_SDCA_QUIRKS=y
caused unmet direct dependency warning with randconig.
The reason is that SND_SOC_ACPI_INTEL_MATCH is needed to be compilable
even if ACPI is not selected, modules have dependency on exported
symbols from it.
The only solution for these kconfig dependencies seams to be to
only select SND_SOC_SDCA if ACPI is enabled from
SND_SOC_ACPI_INTEL_SDCA_QUIRKS.
Regards,
Peter

On 2 x Intel Sapphire Rapids machines with 224 logical CPUs, a poorly
behaving BPF scheduler can live-lock the system by making multiple CPUs bang
on the same DSQ to the point where soft-lockup detection triggers before
SCX's own watchdog can take action. It also seems possible that the machine
can be live-locked enough to prevent scx_ops_helper, which is an RT task,
from running in a timely manner.
Implement scx_softlockup() which is called when three quarters of
soft-lockup threshold has passed. The function immediately enables the ops
breather and triggers an ops error to initiate ejection of the BPF
scheduler.
The previous and this patch combined enable the kernel to reliably recover
the system from live-lock conditions that can be triggered by a poorly
behaving BPF scheduler on Intel dual socket systems.

A poorly behaving BPF scheduler can live-lock the system by e.g. incessantly
banging on the same DSQ on a large NUMA system to the point where switching
to the bypass mode can take a long time. Turning on the bypass mode requires
dequeueing and re-enqueueing currently runnable tasks, if the DSQs that they
are on are live-locked, this can take tens of seconds cascading into other
failures. This was observed on 2 x Intel Sapphire Rapids machines with 224
logical CPUs.
Inject artifical delays while the bypass mode is switching to guarantee
timely completion.
While at it, move __scx_ops_bypass_lock into scx_ops_bypass() and rename it
to bypass_lock.

In the bpf_out_neigh_v6 function, rcu_read_lock() is used to begin an RCU
read-side critical section. However, when unlocking, one branch
incorrectly uses a different RCU unlock flavour rcu_read_unlock_bh()
instead of rcu_read_unlock(). This mismatch in RCU locking flavours can
lead to unexpected behavior and potential concurrency issues.
This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.
This patch corrects the mismatched unlock flavour by replacing the
incorrect rcu_read_unlock_bh() with the appropriate rcu_read_unlock(),
ensuring that the RCU critical section is properly exited. This change
prevents potential synchronization issues and aligns with proper RCU
usage patterns.

With warnings added for deprecated #address-cells/#size-cells handling,
the DT address handling code causes warnings when used on nodes with no
address. This happens frequently with calls to of_platform_populate() as
it is perfectly acceptable to have devices without a 'reg' property. The
desired behavior is to just silently return an error when retrieving an
address.
The warnings can be avoided by checking for "#address-cells" presence
first and checking for an address property before fetching
"#address-cells" and "#size-cells".

While OpenFirmware originally allowed walking parent nodes and default
root values for #address-cells and #size-cells, FDT has long required
explicit values. It's been a warning in dtc for the root node since the
beginning (2005) and for any parent node since 2007. Of course, not all
FDT uses dtc, but that should be the majority by far. The various
extracted OF devicetrees I have dating back to the 1990s (various
PowerMac, OLPC, PASemi Nemo) all have explicit root node properties. The
warning is disabled for Sparc as there are known systems relying on
default root node values.

FDT systems should never be relying on default cell sizes. It's been a
warning in dtc since 2007. The behavior here doesn't even match the
unflattened code which will walk the parent nodes looking for the cell
size properties (also deprecated). Furthermore, the FDT address
translation code is only used in one spot by SH and for earlycon which
was added 2014 and certainly isn't used on Powerpc systems.
Returning -1 values will result in an error message.

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205acd3c ("i2c: designware: fix __i2c_dw_disable() in

MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when

resulting in them sometimes being accidentally freed: this dated
from pre-cycle detector, when we could leave them locked. This
should have resulted in more explosions and fireworks, but turned
out to be surprisingly hard to hit because the preallocated nodes
were being used right away.
The fix for this is bigger than we'd like - reworking btree list

some user-visible floating point register corruption. Both of the
Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.

Anyway, the good news is that we're removing a lot more code than

- Fix handling of SVE traps from userspace on preemptible kernels
when converting the saved floating point state into SVE state.
- Remove broken support for the SMCCCv1.3 "SVE discard hint"

When flag_is_changeable_p() is unused, it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y:
arch/x86/kernel/cpu/common.c:351:19: error: unused function 'flag_is_changeable_p' [-Werror,-Wunused-function]
351 | static inline int flag_is_changeable_p(u32 flag)
| ^~~~~~~~~~~~~~~~~~~~
Fix this by moving core around to make sure flag_is_changeable_p() is
always being used.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
While at it, fix the argument type to be unsigned long along with
the local variables, although it currently only runs in 32-bit cases.
Besides that, makes it return boolean instead of int. This induces
the change of the returning type of have_cpuid_p() to be boolean
as well.

Add preparation patches for coming soon DCD changes.
- Add range_overlaps()
- Add CDAT/DSMAS shared and read only flag in ACPICA
- Add documentation to struct dev_dax_range
- Delay event buffer allocation in CXL PCI
- Use guard() in cxl_dpa_set_mode()
- Refactor common create region code to reduce redudant code

[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.
[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer

[Why]

dmcub won't enable region6.
[How]
Use region6 size in dmcub_fw_meta instead of a constant value.

Number of taps is incorrectly being set when integer scaling is enabled.
Taps required when src_rect != dst_rect previously not considered.
Perform the calculations when integer scaling is enabled.
Set taps to 1 if the scaling ratio is 1:1.

Unconditionally reading DP tunneling support results in extraneous

[Why]
In certain use case such as KDE login screen, there will be no atomic
commit while do the frame update.
If the Panel Replay enabled, it will cause the screen not updated and
looks like system hang.
[How]
Delay few atomic commits before enabled the Panel Replay just like PSR.

Enable the cleaner shader for GFX11.0.0/11.0.2 GPUs to provide data
isolation between GPU workloads. The cleaner shader is responsible for
clearing the Local Data Store (LDS), Vector General Purpose Registers
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps
prevent data leakage and ensures accurate computation results.
This update extends cleaner shader support to GFX11.0.0/11.0.2 GPUs,
previously available for GFX11.0.3. It enhances security by clearing GPU
memory between processes and maintains a consistent GPU state across KGD
and KFD workloads.
