Update the coretemp documentation to reflect current driver capabilities:
- Extend the supported CPU model list to include Atom processors from
Bonnell through Jasper Lake, maintaining the original format with
model numbers and adding X86_FEATURE_DTHERM as the actual detection
mechanism. Added models: 0x37 (Bay Trail), 0x4a (Merrifield),
0x4c (Cherry Trail), 0x5a (Moorefield), 0x5c (Apollo Lake),
0x7a (Gemini Lake), 0x96 (Elkhart Lake), 0x9c (Jasper Lake)
- Update the description to note that per-package temperature sensing
is available on Sandy Bridge and all newer processors
- Clarify that TjMax is read from MSR_IA32_TEMPERATURE_TARGET on modern
CPUs (Nehalem and newer)
- Add TjMax values for newer Atom processor families to Appendix A:
- 22nm Silvermont/Bay Trail: E38xx at 110C, Z37xx at 90C
- 22nm Silvermont/Moorefield: Z35xx at 90C
- 14nm Airmont/Cherry Trail: Z8xxx at 90C
- 14nm Goldmont/Apollo Lake: 105C
- 14nm Goldmont Plus/Gemini Lake: 105C
- 10nm Tremont/Elkhart Lake: 105C
- 10nm Tremont/Jasper Lake: 105C
TjMax values obtained from Intel ARK and official datasheets:

The current documentation advises against calculations in macros
primarily to avoid code obfuscation. It misses the risk of concurrency
issues.
Add a note explaining that macros evaluating arguments multiple times
can lead to race conditions when accessing shared data.

The root document usually has a special :ref:`genindex` link to the
generated index. This is also the case for Documentation/index.rst. The
other index.rst files deeper in the directory hierarchy usually don't.
For SPHINXDIRS builds, the root document isn't Documentation/index.rst,
but some other index.rst in the hierarchy. Currently they have a
".. only::" block to add the index link when doing SPHINXDIRS html
builds.
This is obviously very tedious and repetitive. The link is also added to
all index.rst files in the hierarchy for SPHINXDIRS builds, not just the
root document.
Put the boilerplate in a sphinx-includes/subproject-index.rst file, and
include it at the end of the root document for subproject builds in an
ad-hoc source-read extension defined in conf.py.
For now, keep having the boilerplate in translations, because this
approach currently doesn't cover translated index link headers.

The System Management Controller on Apple Silicon devices is responsible
for integrating and exposing the data reported by the vast array of
hardware monitoring sensors present on these devices. It is also
responsible for fan control, and allows users to manually set fan
speeds if they so desire. Add a hwmon driver to expose current,
power, temperature, and voltage monitoring sensors, as well as
fan speed monitoring and control via the SMC on Apple Silicon devices.
The SMC firmware has no consistency between devices, even when they
share an SoC. The FourCC keys used to access sensors are almost
random. An M1 Mac mini will have different FourCCs for its CPU core
temperature sensors to an M1 MacBook Pro, for example. For this
reason, the valid sensors for a given device are specified in a
child of the SMC Devicetree node. The driver uses this information
to determine which sensors to make available at runtime.

Register fans connected under EC as thermal cooling devices as well, so
these fans can then work with the thermal framework.
During the driver probing phase, we will also try to register each fan
as a thermal cooling device based on previous probe result (whether the
there are fans connected on that channel, and whether EC supports fan
control). The basic get max state, get current state, and set current
state methods are then implemented as well.

Newer EC firmware supports controlling fans through host commands, so
adding corresponding implementations for controlling these fans in the
driver for other kernel services and userspace to control them.
The driver will first probe the supported host command versions (get and
set of fan PWM values, get and set of fan control mode) to see if the
connected EC fulfills the requirements of controlling the fan, then
exposes corresponding sysfs nodes for userspace to control the fan with
corresponding read and write implementations.
As EC will automatically change the fan mode to auto when the device is
suspended, the power management hooks are added as well to keep the fan
control mode and fan PWM value consistent during suspend and resume. As
we need to access the hwmon device in the power management hook, update
the driver by storing the hwmon device in the driver data as well.

Many machines treat fan state 3 as some sort of automatic mode,
which is superior to the separate SMM calls for switching to
automatic fan mode for two reasons:
- the fan control mode can be controlled for each fan separately
- the current fan control mode can be retrieved from the BIOS
On some machines however, this special fan state does not exist.
Fan state 3 acts like a regular fan state on such machines or
does not exist at all. Such machines usually use separate SMM calls
for enabling/disabling automatic fan control.
Add support for it. If the machine supports separate SMM calls
for changing the fan control mode, then the other interface is
ignored.

Implement locking in the hardware monitoring core for drivers using
the _with_info() API functions.
Most hardware monitoring drivers need to support locking to protect
against parallel accesses from userspace. With older API functions, such
locking had to be implemented in the driver code since sysfs attributes
were created by the driver. However, the _with_info() API creates sysfs
attributes in the hardware monitoring core. This makes it easy to move
the locking primitives into that code. This has the benefit of simplifying
driver code while at the same time reducing the risk of incomplete of bad
locking implementations in hardware monitoring drivers.
While this means that all accesses are forced to be synchronized, this
has little if any practical impact since accesses are expected to be low
frequency and are typically synchronized from userspace anyway since
only a single process is accessing the data. On top of that, many drivers
use regmap, which also has its own locking scheme and already serializes
accesses.
