The driver registers a thermal zone for each transceiver module and
tries to set the trip point temperatures according to the thresholds
read from the transceiver. If a threshold cannot be read or if a
transceiver is unplugged, the trip point temperature is set to zero,
which means that it is disabled as far as the thermal subsystem is
concerned.
A recent change in the thermal core made it so that such trip points are
no longer marked as disabled, which lead the thermal subsystem to
incorrectly set the associated cooling devices to the their maximum
state [1]. A fix to restore this behavior was merged in commit
f1b80a3878 ("thermal: core: Restore behavior regarding invalid trip
points"). However, the thermal maintainer suggested to not rely on this
behavior and instead always register a valid array of trip points [2].
Therefore, create a static array of trip points with sane defaults
(suggested by Vadim) and register it with the thermal zone of each
transceiver module. User space can choose to override these defaults
using the thermal zone sysfs interface since these files are writeable.
Before:
$ cat /sys/class/thermal/thermal_zone11/type
mlxsw-module11
$ cat /sys/class/thermal/thermal_zone11/trip_point_*_temp
65000
75000
80000
After:
$ cat /sys/class/thermal/thermal_zone11/type
mlxsw-module11
$ cat /sys/class/thermal/thermal_zone11/trip_point_*_temp
55000
65000
80000
Also tested by reverting commit f1b80a3878 ("thermal: core: Restore
behavior regarding invalid trip points") and making sure that the
associated cooling devices are not set to their maximum state.

Based on further tests, it seems that the QDMA shaper is not able to
perform shaping close to the MAC link rate without throughput loss.
This cannot be compensated by increasing the shaping rate, so it seems
to be an internal limit.
Fix the remaining throughput regression by detecting that condition and
limiting shaping to ports with lower link speed.
This patch intentionally ignores link speed gain from TRGMII, because
even on such links, shaping to 1000 Mbit/s incurs some throughput
degradation.

Commit 0db3dc73f7 ("[NETPOLL]: tx lock deadlock fix") narrowed
down the region under netif_tx_trylock() inside netpoll_send_skb().
(At that point in time netif_tx_trylock() would lock all queues of
the device.) Taking the tx lock was problematic because driver's
cleanup method may take the same lock. So the change made us hold
the xmit lock only around xmit, and expected the driver to take
care of locking within ->ndo_poll_controller().
Unfortunately this only works if netpoll isn't itself called with
the xmit lock already held. Netpoll code is careful and uses
trylock(). The drivers, however, may be using plain lock().
Printing while holding the xmit lock is going to result in rare
deadlocks.
Luckily we record the xmit lock owners, so we can scan all the queues,
the same way we scan NAPI owners. If any of the xmit locks is held
by the local CPU we better not attempt any polling.
It would be nice if we could narrow down the check to only the NAPIs
and the queue we're trying to use. I don't see a way to do that now.

====================
In commit 22df776a9a ("tasks: Extract rcu_users out of union"), the
'refcount_t rcu_users' field was extracted out of a union with the
'struct rcu_head rcu' field. This allows us to use the field for
refcounting struct task_struct with RCU protection, as the RCU callback
no longer flips rcu_users to be nonzero after the callback is scheduled.
This patch set leverages this to do a few things:
1. Marks struct task_struct as RCU safe in the verifier, allowing
referenced kptr tasks stored in maps to be accessed in an RCU
read region without acquiring a reference (with just a NULL check).
2. Makes bpf_task_acquire() a KF_ACQUIRE | KF_RCU | KF_RET_NULL kfunc.
3. Removes bpf_task_kptr_get() and bpf_task_acquire_not_zero(), as
they're now redundant with the above two changes.
4. Updates selftests and documentation accordingly.

In commit 22df776a9a ("tasks: Extract rcu_users out of union"), the
'refcount_t rcu_users' field was extracted out of a union with the
'struct rcu_head rcu' field. This allows us to safely perform a
refcount_inc_not_zero() on task->rcu_users when acquiring a reference on
a task struct. A prior patch leveraged this by making struct task_struct
an RCU-protected object in the verifier, and by bpf_task_acquire() to
use the task->rcu_users field for synchronization.
Now that we can use RCU to protect tasks, we no longer need
bpf_task_kptr_get(), or bpf_task_acquire_not_zero(). bpf_task_kptr_get()
is truly completely unnecessary, as we can just use RCU to get the
object. bpf_task_acquire_not_zero() is now equivalent to
bpf_task_acquire().
In addition to these changes, this patch also updates the associated
selftests to no longer use these kfuncs.

struct task_struct objects are a bit interesting in terms of how their
lifetime is protected by refcounts. task structs have two refcount
fields:
1. refcount_t usage: Protects the memory backing the task struct. When
this refcount drops to 0, the task is immediately freed, without
waiting for an RCU grace period to elapse. This is the field that
most callers in the kernel currently use to ensure that a task
remains valid while it's being referenced, and is what's currently
tracked with bpf_task_acquire() and bpf_task_release().
2. refcount_t rcu_users: A refcount field which, when it drops to 0,
schedules an RCU callback that drops a reference held on the 'usage'
field above (which is acquired when the task is first created). This
field therefore provides a form of RCU protection on the task by
ensuring that at least one 'usage' refcount will be held until an RCU
grace period has elapsed. The qualifier "a form of" is important
here, as a task can remain valid after task->rcu_users has dropped to
0 and the subsequent RCU gp has elapsed.
In terms of BPF, we want to use task->rcu_users to protect tasks that
function as referenced kptrs, and to allow tasks stored as referenced
kptrs in maps to be accessed with RCU protection.
Let's first determine whether we can safely use task->rcu_users to
protect tasks stored in maps. All of the bpf_task* kfuncs can only be
called from tracepoint, struct_ops, or BPF_PROG_TYPE_SCHED_CLS, program
types. For tracepoint and struct_ops programs, the struct task_struct
passed to a program handler will always be trusted, so it will always be
safe to call bpf_task_acquire() with any task passed to a program.
Note, however, that we must update bpf_task_acquire() to be KF_RET_NULL,
as it is possible that the task has exited by the time the program is
invoked, even if the pointer is still currently valid because the main
kernel holds a task->usage refcount. For BPF_PROG_TYPE_SCHED_CLS, tasks
should never be passed as an argument to the any program handlers, so it
should not be relevant.
The second question is whether it's safe to use RCU to access a task
that was acquired with bpf_task_acquire(), and stored in a map. Because
bpf_task_acquire() now uses task->rcu_users, it follows that if the task
is present in the map, that it must have had at least one
task->rcu_users refcount by the time the current RCU cs was started.
Therefore, it's safe to access that task until the end of the current
RCU cs.
With all that said, this patch makes struct task_struct is an
RCU-protected object. In doing so, we also change bpf_task_acquire() to
be KF_ACQUIRE | KF_RCU | KF_RET_NULL, and adjust any selftests as
necessary. A subsequent patch will remove bpf_task_kptr_get(), and
bpf_task_acquire_not_zero() respectively.

When a DRM driver turns on or off the screen with the audio
capability, it notifies the ELD to HD-audio HDMI codec driver via
component ops. HDMI codec driver, in turn, attaches or detaches the
PCM stream for the given port on the fly.
The problem is that, since the recent code change, the HDMI driver
always treats the PCM stream assignment dynamically; this ended up the
confusion of the PCM device appearance. e.g. when a screen goes once
off and on again, it may appear on a different PCM device before the
screen-off. Although the application should treat such a change, it
doesn't seem working gracefully with the current pipewire (maybe
PulseAudio, too).
As a workaround, this patch changes the HDMI codec driver behavior
slightly to be more consistent. Now it remembers the previous PCM
slot for the given port and try to assign to it. That is, if a port
is re-enabled, the driver tries to use the same PCM slot that was
assigned to that port previously. If it conflicts, a new slot is
searched and used like before, instead.
Note that multiple monitor connections are the only typical case where
the PCM slot preservation is effective. As long as only a single
monitor is connected, the behavior isn't changed, and the first PCM
slot is still assigned always.

The fork function in gcc is considered a built in function due to
being used by libgcov when building with gnu extensions.
Rename fork to sched_process_fork to prevent this conflict.

Commit 5829f8a897 ("platform/x86: ideapad-laptop: Send
KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send
KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set
and the touchpad-state has not been changed by the EC itself already.
This was done under the assumption that this would be good to do to make
the touchpad-toggle hotkey work on newer models where the EC does not
toggle the touchpad on/off itself (because it is not routed through
the PS/2 controller, but uses I2C).
But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC
triggers an ACPI notify with VPC event bit 5 set on resume, which would
now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop
environment responds by disabling the touchpad in software, breaking
the touchpad (until manually re-enabled) on resume.
It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves
things on new models and at least some new models like the Yoga 7-15ITL5
don't have a touchpad on/off toggle hotkey at all, while still sending
ACPI notify events with VPC event bit 5 set.
So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when
receiving an ACPI notify events with VPC event bit 5 and the touchpad
state as reported by the EC has not changed.
Note this is not a full revert the code to cache the last EC touchpad
state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events
on resume.

Pull thermal control fixes from Rafael Wysocki:
"These remove two recently added excessive lockdep assertions from the
sysfs-related thermal code and fix two issues in Intel thermal
drivers.
Specifics:
- Drop two lockdep assertions producing false positive warnings from
the sysfs-related thermal core code (Rafael Wysocki)
- Fix handling of two recently added module parameters in the Intel
powerclamp thermal driver (David Arcari)
- Fix one more deadlock in the int340x thermal driver (Srinivas
Pandruvada)"

Pull ACPI fix from Rafael Wysocki:
"Fix a recent regression related to the handling of ACPI notifications
that made it more likely for ACPI driver callbacks to be invoked in an
unexpected order and NULL pointers can be dereferenced as a result or
similar.
The fix is to modify the global ACPI notification handler so it does
not invoke driver callbacks at all and allow the device-level
notification handlers to receive "system" notifications (for the
drivers that want to receive them)"
