Merge tag 'v5.4-rc4' into docs-next
I need to pick up the independent changes made to Documentation/core-api/memory-allocation.rst to be able to merge further work without creating a total mess.

If the BIOS has enabled hardware temperature control, the threshold at
which the processor will throttle itself to avoid damage is available in
temp1_crit and temp1_crit_hyst.
+
+On some AMD CPUs, there is a difference between the die temperature (Tdie) and
+the reported temperature (Tctl). Tdie is the real measured temperature, and
+Tctl is used for fan control. While Tctl is always available as temp1_input,
+the driver exports Tdie temperature as temp2_input for those CPUs which support
+it.
+
+Models from 17h family report relative temperature, the driver aims to
+compensate and report the real temperature.
