Pull to receive the __arena argument conversion:

67f1f4a48c24 ("sched_ext: Pass kernel arena pointers to ops_cid callbacks")
a8dc810968af ("sched_ext: Convert sub-cap kfuncs to __arena cmask arguments")
a05c5b5cb5cf ("sched_ext: Convert scx_bpf_cid_override() to __arena array arguments")

along with the bpf-next branch carrying the __arena argument support they
depend on.

Conflict in kernel/sched/ext/ext.c between:

c384ab8a0b13 ("sched_ext: Move the config-off sub-cap kfunc stubs into sub.c")

and:

a8dc810968af ("sched_ext: Convert sub-cap kfuncs to __arena cmask arguments")

which updated the stubs in their old ext.c location. Resolved by keeping
ext.c without the stubs and applying the prototype conversion to the
relocated stubs in sub.c.

ASoC: cs35l3x: drain threaded IRQs before runtime suspend

ASoC: cs35l3x: drain threaded IRQs before runtime suspend

Runyu Xiao <runyu.xiao@seu.edu.cn> says:

Both cs35l33 and cs35l34 can enter runtime suspend while their threaded
IRQ handlers are still reachable. The suspend path then switches the
driver into regcache cache-only mode and powers the codec down, while
the IRQ thread still expects live status-register access.

This issue was found by our static analysis tool and manually audited on
Linux v6.18.21. Directed QEMU no-device validation further showed that,
after runtime_suspend() completed, the real threaded handlers could
still be injected and would continue past volatile regmap read failures
into their release/update paths.

This series keeps the fix on the suspend actor and applies the same
runtime-suspend/threaded-IRQ ordering repair boundary to both drivers:

- track whether request_threaded_irq() actually succeeded
- disable_irq() before cache_only/power-off in runtime suspend
- enable_irq() only after regcache_sync() in runtime resume

That drains any in-flight threaded handler and blocks new IRQ handling
while the codec is suspended, without mixing in larger IRQ-thread
defensive cleanups.

Build-tested by compiling cs35l33.o and cs35l34.o.

No cs35l33/cs35l34 hardware was available for end-to-end runtime
testing.

spi: Enable SPI on SA8255p Qualcomm platforms

Praveen Talari <praveen.talari@oss.qualcomm.com> says:

The Qualcomm automotive SA8255p SoC relies on firmware to configure
platform resources, including clocks, interconnects and TLMM.
The driver requests resources operations over SCMI using power
and performance protocols.

The SCMI power protocol enables or disables resources like clocks,
interconnect paths, and TLMM (GPIOs) using runtime PM framework APIs,
such as resume/suspend, to control power states(on/off).

The SCMI performance protocol manages SPI frequency, with each
frequency rate represented by a performance level. The driver uses
geni_se_set_perf_opp() API to request the desired frequency rate.

As part of geni_se_set_perf_opp(), the OPP for the requested frequency
is obtained using dev_pm_opp_find_freq_floor() and the performance
level is set using dev_pm_opp_set_opp().

Pull mod_devicetable.h header split from Uwe Kleine-König:
"Split <linux/mod_devicetable.h> in per subsystem headers

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:

$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038

The result of this mixture of different and unrelated subsystem
details is that even when touching an obscure device id struct most of
the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per
subsystem headers and only including what is really needed reduces the
amount of needed recompilation.

This split is implemented in the first commit and then after some
preparatory work in the following commits, the last two replace
includes of <linux/mod_devicetable.h> by the actually needed more
specific headers.

There are still a few instances left, but the ones with high impact
(that is in headers that are used a lot) and the easy ones (.c files)
are handled. These remaining includes will be addressed during the
next merge window"

mod_devicetable.h: Split into per subsystem headers

driver in an x86_64 allmodconfig build of v7.1:

$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038

The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.

Implement the first step and define each device id struct in a separate
header (together with its associated #defines).

<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.

Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:

$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

include/linux/input.h:1205
include/linux/mdio.h:835
include/linux/phy.h:733

struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.
