Prevent the PWM value from being set to minimum when thermal zone
temperature exceeds any trip point during driver probe. Otherwise, the
PWM fan speed will remains at minimum speed and not respond to
temperature changes.

Add support for using the AMC6821 as a cooling device. The AMC6821
registers with the thermal framework only if the `cooling-levels`
property is present in the fan device tree child node. If this property
is present, the driver assumes the fan will operate in open-loop, and
the kernel will control it directly. In this case, the driver will
change the AMC6821 mode to manual (software DCY) and set the initial PWM
duty cycle to the maximum fan cooling state level as defined in the DT.
It is worth mentioning that the cooling device is registered on the
child fan node, not on the fan controller node. Existing behavior is
unchanged, so the AMC6821 can still be used without the thermal
framework (hwmon only).

The Linux hwmon sysfs API values for pwmX_auto_pointY_pwm represent an
integer value between 0 (0%) to 255 (100%) and the pwmX_auto_pointY_temp
represent millidegrees Celcius.
Commit a6d80df47ee2 ("hwmon: (gsc-hwmon) fix fan pwm temperature
scaling") properly addressed the incorrect scaling in the
pwm_auto_point_temp_store implementation but erroneously scaled
the pwm_auto_point_pwm_show (pwm value) instead of the
pwm_auto_point_temp_show (temp value) resulting in:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
25500
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp
4500
Fix the scaling of these attributes:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
255
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp
45000

Pull tracing fixes from Steven Rostedt:
- Fix timerlat with use of FORTIFY_SOURCE
FORTIFY_SOURCE was added to the stack tracer where it compares the
entry->caller array to having entry->size elements.
timerlat has the following:
memcpy(&entry->caller, fstack->calls, size);
entry->size = size;
Which triggers FORTIFY_SOURCE as the caller is populated before the
entry->size is initialized.
Swap the order to satisfy FORTIFY_SOURCE logic.
- Add down_write(trace_event_sem) when adding trace events in modules
Trace events being added to the ftrace_events array are protected by
the trace_event_sem semaphore. But when loading modules that have
trace events, the addition of the events are not protected by the
semaphore and loading two modules that have events at the same time
can corrupt the list.
Also add a lockdep_assert_held(trace_event_sem) to
_trace_add_event_dirs() to confirm it is held when iterating the
list.

A recent commit changed the runqueue counter nr_uninterruptible to an

migration of a uninterruptble task to a different CPU, these counters

The counter is cast to long in the load average calculation, which

When a module is loaded, it adds trace events defined by the module. It
may also need to modify the modules trace printk formats to replace enum
names with their values.
If two modules are loaded at the same time, the adding of the event to the
ftrace_events list can corrupt the walking of the list in the code that is
modifying the printk format strings and crash the kernel.
The addition of the event should take the trace_event_sem for write while
it adds the new event.
Also add a lockdep_assert_held() on that semaphore in
__trace_add_event_dirs() as it iterates the list.

We have observed kernel panics when using timerlat with stack saving,
with the following dmesg output:
memcpy: detected buffer overflow: 88 byte write of buffer size 0

__timerlat_dump_stack() constructs the ftrace stack entry like this:
struct stack_entry *entry;
...
memcpy(&entry->caller, fstack->calls, size);
entry->size = fstack->nr_entries;
Since commit e7186af7fb26 ("tracing: Add back FORTIFY_SOURCE logic to
kernel_stack event structure"), struct stack_entry marks its caller
field with __counted_by(size). At the time of the memcpy, entry->size
contains garbage from the ringbuffer, which under some circumstances is
zero, triggering a kernel panic by buffer overflow.
Populate the size field before the memcpy so that the out-of-bounds
check knows the correct size. This is analogous to
__ftrace_trace_stack().
