a2af49293d dt-bindings: net: snps, dwmac: remove tx-sched-sp property
Strict priority for the tx scheduler is by default in Linux driver, so the
tx-sched-sp property was removed in commit aed6864035 ("net: stmmac:
platform: Delete a redundant condition branch").

This property is still in use in the following DT (and it will be removed
in a separate patch series):

- arch/arm64/boot/dts/freescale/imx8mp-beacon-som.dtsi
- arch/arm64/boot/dts/freescale/imx8mp-evk.dts
- arch/arm64/boot/dts/freescale/imx8mp-verdin.dtsi
- arch/arm64/boot/dts/qcom/sa8540p-ride.dts
- arch/arm64/boot/dts/qcom/sa8775p-ride.dts

There is no problem if that property is still used in the DTs above,
since, as seen above, it is a default property of the driver.

98369dccd2 Merge tag 'wq-for-6.9-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
Pull workqueue fixes from Tejun Heo:
 "Two doc update patches and the following three fixes:

   - On single node systems, the default pool is used but the
     node_nr_active for the default pool was set to min_active. This
     effectively limited the max concurrency of unbound pools on single
     node systems to 8 causing performance regressions on some
     workloads. Fixed by setting the default pool's node_nr_active to
     max_active.

   - wq_update_node_max_active() could trigger divide-by-zero if the
     intersection between the allowed CPUs for an unbound workqueue and
     online CPUs becomes empty.

   - When kick_pool() was trying to repatriate a worker to a CPU in its
     pod by setting task->wake_cpu, it didn't consider whether the CPU
     being selected is online or not which obviously can lead to
     subobtimal behaviors. On s390, this triggered a crash in arch code.
     The workqueue patch removes the gross misbehavior but doesn't fix
     the crash completely as there's a race window in which CPUs can go
     down after wake_cpu is set. Need to decide whether the fix should
     be on the core or arch side"

5097cbcb38 sched/isolation: Prevent boot crash when the boot CPU is nohz_full
Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not
include the boot CPU, which is no longer true after:

  08ae95f4fd ("nohz_full: Allow the boot CPU to be nohz_full").

However after:

  aae17ebb53 ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")

the kernel will crash at boot time in this case; housekeeping_any_cpu()
returns an invalid CPU number until smp_init() brings the first
housekeeping CPU up.

Change housekeeping_any_cpu() to check the result of cpumask_any_and() and
return smp_processor_id() in this case.

This is just the simple and backportable workaround which fixes the
symptom, but smp_processor_id() at boot time should be safe at least for
type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu
logic.

There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to
offline tick_do_timer_cpu (the 1st online housekeeping CPU).

Fixes: aae17ebb53 ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")

  Most of these changes are machine specific fixups, but there are a few
  notable regressions that affect an entire SoC:

   - The Qualcomm MSI support that was improved for 6.9 ended up being
     wrong on some chips and now gets fixed.

   - The i.MX8MP camera interface broke due to a typo and gets updated
     again.

  The main driver fix is also for Qualcomm platforms, rewriting an
  interface in the QSEECOM firmware support that could lead to crashing
  the kernel from a trusted application.

  The only other code changes are minor fixes for Mediatek SoC drivers"

ce0abef6a1 cpu: Ignore "mitigations" kernel parameter if CPU_MITIGATIONS=n
Explicitly disallow enabling mitigations at runtime for kernels that were
built with CONFIG_CPU_MITIGATIONS=n, as some architectures may omit code
entirely if mitigations are disabled at compile time.

E.g. on x86, a large pile of Kconfigs are buried behind CPU_MITIGATIONS,
and trying to provide sane behavior for retroactively enabling mitigations
is extremely difficult, bordering on impossible.  E.g. page table isolation
and call depth tracking require build-time support, BHI mitigations will
still be off without additional kernel parameters, etc.

b17181a88f dt-bindings: net: pse-pd: Add another way of describing several PSE PIs
PSE PI setup may encompass multiple PSE controllers or auxiliary circuits
that collectively manage power delivery to one Ethernet port.
Such configurations might support a range of PoE standards and require
the capability to dynamically configure power delivery based on the
operational mode (e.g., PoE2 versus PoE4) or specific requirements of
connected devices. In these instances, a dedicated PSE PI node becomes
essential for accurately documenting the system architecture. This node
would serve to detail the interactions between different PSE controllers,
the support for various PoE modes, and any additional logic required to
coordinate power delivery across the network infrastructure.

The old usage of "#pse-cells" is unsuficient as it carries only the PSE PI
index information.

9be9567a7c net: pse-pd: Add support for PSE PIs
The Power Sourcing Equipment Power Interface (PSE PI) plays a pivotal role
in the architecture of Power over Ethernet (PoE) systems. It is essentially
a blueprint that outlines how one or multiple power sources are connected
to the eight-pin modular jack, commonly known as the Ethernet RJ45 port.
This connection scheme is crucial for enabling the delivery of power
alongside data over Ethernet cables.

This patch adds support for getting the PSE controller node through PSE PI
device subnode.

This supports adds a way to get the PSE PI id from the pse_pi devicetree
subnode of a PSE controller node simply by reading the reg property.

b58be8db63 ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL
In the current PSE interface for Ethernet Power Equipment, support is
limited to PoDL. This patch extends the interface to accommodate the
objects specified in IEEE 802.3-2022 145.2 for Power sourcing
Equipment (PSE).

The following objects are now supported and considered mandatory:
- IEEE 802.3-2022 30.9.1.1.5 aPSEPowerDetectionStatus
- IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState
- IEEE 802.3-2022 30.9.1.2.1 aPSEAdminControl

To avoid confusion between "PoDL PSE" and "PoE PSE", which have similar
names but distinct values, we have followed the suggestion of Oleksij
Rempel and Andrew Lunn to maintain separate naming schemes for each,
using c33 (clause 33) prefix for "PoE PSE".

f5c12105c1 mm,page_owner: fix refcount imbalance
Current code does not contemplate scenarios were an allocation and free
operation on the same pages do not handle it in the same amount at once. 
To give an example, page_alloc_exact(), where we will allocate a page of
enough order to stafisfy the size request, but we will free the remainings
right away.

In the above example, we will increment the stack_record refcount only
once, but we will decrease it the same number of times as number of unused
pages we have to free.  This will lead to a warning because of refcount
imbalance.

Fix this by recording the number of base pages in the refcount field.

abbb99301e docs: verify/bisect: use git switch, tag kernel, and various fixes
Various small improvements and fixes:

* Use the more modern 'git switch' instead of 'git checkout', which
  makes it more obvious what's happening (among others due to the
  --discard-changes parameter that is more clear than --force).

* Provide a hint how a mainline version number and one from a stable
  series look like.

* When trying to validate the bisection result with a revert, add a
  special tag to facilitate the identification.

* Sync version numbers used in various examples for consistency: stick
  to 6.0.13, 6.0.15, and 6.1.5.

* Fix a few typos and oddities.

fb7c3d8ba0 dt-bindings: pwm: mediatek,pwm-disp: Document power-domains property
Allow the power-domains property to the PWM_DISP block as on some SoCs
this does need at most one power domain.

Fixes: b09b179bac ("dt-bindings: pwm: Convert pwm-mtk-disp.txt to mediatek,pwm-disp.yaml format")

399f4dae68 Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull virtio bugfixes from Michael Tsirkin:
 "Some small, obvious (in hindsight) bugfixes:

   - new ioctl in vhost-vdpa has a wrong # - not too late to fix

   - vhost has apparently been lacking an smp_rmb() - due to code
     duplication :( The duplication will be fixed in the next merge
     cycle, this is a minimal fix

   - an error message in vhost talks about guest moving used index -
     which of course never happens, guest only ever moves the available
     index

   - i2c-virtio didn't set the driver owner so it did not get refcounted
     correctly"

* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
  vhost: correct misleading printing information
  vhost-vdpa: change ioctl # for VDPA_GET_VRING_SIZE
  virtio: store owner from modules with register_virtio_driver()
  vhost: Add smp_rmb() in vhost_enable_notify()
  vhost: Add smp_rmb() in vhost_vq_avail_empty()
