commit cf948c8e274e8b406e846cdf6cc48fe47f98cf57 upstream.

The tj_max value obtained from the Intel TCC library are in Celsius,
whereas the thermal subsystem operates in milli-Celsius.

This discrepancy leads to incorrect trip temperature calculations.

Fix bogus trip temperature by converting tj_max to milli-Celsius Unit.

[ Upstream commit 00c5ff5e9a55dca2e7ca29af4e5f8708731faf11 ]

Panther Lake uses the same DLVR register offsets as Lunar Lake, but the
driver uses the default register offsets table for it by mistake.

Move the selection of register offsets table from the actual attribute
read/write callbacks to proc_thermal_rfim_add() and make it handle
Panther Lake the same way as Lunar Lake.  This way it is clean and in
the future such issues can be avoided.

[ Upstream commit 2542a3f70e563a9e70e7ded314286535a3321bdb ]

Not all devices have an ACPI companion fwnode, so adev might be NULL.
This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").

Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in int3402_thermal_probe().

Note, under the same directory, int3400_thermal_probe() has such a
check.

If CONFIG_NET is not defined then THERMAL_NETLINK can't be selected.

Hence add dependency on CONFIG_NET. Othewise it will generate compile
errors while compiling thermal_netlink.c.

Currently some user space programs like Linux thermald needs to register
to get notifications from both thermal user space governor and also
Thermal netlink. This is required as some messages like HFI (Hardware
Feedback Notifications) requires Thermal netlink.

This results in additional processing in kernel and user space to process
both notifications. The cost of using user space governor using
kobject_uevent is much higher as this is also used by other user space
daemons like udev daemon.

Do not select user_space thermal governor by default. If it is present
user space programs can always use this governor by writing to
"policy" attribute.

Instead from the kernel select THERMAL_NETLINK. Trip temperature
violation can be received by user space programs via thermal netlink
events:
THERMAL_GENL_EVENT_TZ_TRIP_UP
THERMAL_GENL_EVENT_TZ_TRIP_DOWN

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.
