The existing TSENS temperature read logic polls the valid bit and then
reads the temperature register. When temperature reads are triggered
at very short intervals, this can race with hardware updates and allow
the temperature field to be read while it is still being updated.
In this case, the valid bit may already be asserted even though the
temperature value is transitioning, resulting in an incorrect reading.
Hardware programming guidelines require the temperature value and the
valid bit to be sampled atomically in the same read transaction. A
reading is considered valid only if the valid bit is observed set in
that same sample.
The guidelines further specify that software should attempt the
temperature read up to three times to account for transient update
windows. If none of the attempts yields a valid sample, a stable fallback
value must be returned: if the first and second samples match, the second
value is returned;otherwise, if the second and third samples match, the
third value is returned;if neither pair matches, -EAGAIN is returned.
Update the TSENS sensor read logic to implement atomic sampling along
with the recommended retry-and-compare fallback behavior. This removes
the race window and ensures deterministic temperature values in
accordance with hardware requirements.

Use devm_thermal_of_cooling_device_register() to simplify resource

As a side effect this change has the benefit of solving an existing
issue. Before, the function tegra_soctherm_remove() only called
debugfs_remove_recursive() and never called thermal_cooling_device_unregister()
for any of the cooling devices registered here.
After the driver removal, the thermal framework's cdev list would
still hold references to thermal_cooling_device objects whose devdata

devm cleanup.
With this change, the cooling device is unregistered when the driver

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.
This workqueue has no benefits being per-CPU, so make it unbound adding
WQ_UNBOUND, removing also the WQ_POWER_EFFICIENT flag.

Since commit
13f4e660a1 ("thermal/core: Split __thermal_cooling_device_register()
into two functions")
thermal_cooling_device_setup_sysfs() is called before the
->get_max_state() callback in thermal_cooling_device_add().
However, cooling_device_stats_setup() allocates space based on
cdev->max_state, which is not initialized at that point.
With CONFIG_THERMAL_STATISTICS=y, an out of bounds access happens
inside thermal_cooling_device_stats_update(), followed by a kernel
crash:
Unable to handle kernel paging request at virtual address ffff800081329e60

To fix this, restore the original ordering of ->get_max_state() and
thermal_cooling_device_setup_sysfs(). Note that with this reordering,
the dev_set_name() and ->get_max_state() error paths now reach
thermal_cdev_release() without setup_sysfs() having run. This is safe
because cdev->stats is NULL in that case and destroy_sysfs() is a no-op.

In preparation for the upcoming changes separating OF and non-OF code,
split __thermal_cooling_device_register() into allocation and addition
phases.
This allows moving the device node assignment out of the core
initialization path.
This change is not a trivial split. The lifetime of the cooling device
is managed by the device core through put_device(), which triggers
thermal_release() to free all associated resources.
With the introduction of thermal_cooling_device_alloc(), the allocation
path must mirror what thermal_release() undoes. In contrast,
thermal_cooling_device_add() must not perform any rollback and relies
on put_device() for cleanup on error paths. This avoids both double
free and resource leaks.
As part of this rework, add the missing device_initialize() call when
allocating the cooling device.

Instead of passing NULL as the last argument to __hwmon_device_register()
in hwmon_device_register_for_thermal() and then adding each temperature
sysfs attribute to the hwmon device via device_create_file(), redefine
hwmon_device_register_for_thermal() to take an extra_groups argument
that will be passed to __hwmon_device_register(), define an attribute
group with a proper .is_visible() callback for the temperature
attributes and a related attribute groups pointer, and pass the latter
to hwmon_device_register_for_thermal().
This causes the code to be way more straightforward and closer to
what the other users of the hwmon subsystem do.

The current code creates one hwmon device per thermal zone type and that
device is registered under the first thermal zone of the given type.
That turns out to be problematic when the thermal zone holding the
hwmon device is removed.
For example, say that there are two ACPI thermal zones on a system
/sys/devices/virtual/thermal/thermal_zone0/
/sys/devices/virtual/thermal/thermal_zone1/
The current code registers a hwmon class device for thermal_zone0 only:
/sys/devices/virtual/thermal/thermal_zone0/hwmon0/
because the type is "acpitz" for both of them, but it adds a sysfs
attribute that belongs to thermal_zone1 under it:
/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp2_input
There is also
/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input
which belongs to thermal_zone0.
When thermal_zone0 is removed, say because the ACPI thermal driver is
unbound from the underlying platform device, the removal code skips the
removal of hwmon0 because of the temp2_input attribute belonging to
thermal_zone1 which effectively prevents thermal_zone0 removal from
making progress.
To address this problem, rework the thermal hwmon code to register one
hwmon device for each thermal zone, but since user space utilities
produce confusing output in some cases when there are multiple hwmon
devices with the same name attribute value present under thermal zones
of the same type, append the thermal zone ID preceded by an underline
character to the name of the hwmon device registered for that thermal
zone.

Since the return value of thermal_zone_crit_temp_valid() depends on
the behavior of the thermal zone .get_crit_temp() callback which
may change over time in theory, thermal_remove_hwmon_sysfs() may
attempt to remove a critical temperature attribute that has not
been created, passing a pointer to an uninitialized attribute
structure to device_remove_file().
To avoid that, set a flag in struct thermal_hwmon_temp after creating
a critical temperature attribute and use the value of that flag to
decide whether or not the attribute needs to be removed.

Because subprog 0, the main subprog, is considered a global function,
we end up running the arg-tracking dataflow analysis twice on it. That
results in slightly longer verification but mostly in more verbose
verifier logs. This patch fixes it by keeping only the iteration over
global subprogs.
When running over all of Cilium's programs with BPF_LOG_LEVEL2, this
reduces verbosity by ~20% on average.
Fixes: bf0c571f7f ("bpf: introduce forward arg-tracking dataflow analysis")

- Fix spurious failures in rseq self-tests (Mark Brown)
- Fix rseq rseq::cpu_id_start ABI regression due to
TCMalloc's creative use of the supposedly read-only field.
The fix is to introduce a new ABI variant based on
a new (larger) rseq area registration size, to keep
the TCMalloc use of rseq backwards compatible on new kernels.
