The value of the _LPI "State Name" field is used as the description of
the given idle state (that is, the value of its "desc" attribute in
sysfs) which is not consistent with idle state descriptions used when
the idle state information comes from an ACPI _CST object.
To rectify that, use the _LPI "State Name" field value as the value of
the "name" sysfs attribute of a given idle state and use the MWAIT hint
value from the _LPI register address value to derive the value of its
"desc" sysfs attribute in analogy with the _CST case.

The amd_dynamic_epp command-line parameter was removed. Dynamic EPP
is now selected through the per-policy energy_performance_preference
attribute, which is already documented.

Pull documentation updates from Jonathan Corbet:
"It has been a not-too-busy cycle for docs; here's the highlights:
- A (hopefully) consensus change to our LLM-attribution requirements,
removing the specific model name from the Assisted-by tag
- A couple of new realtime documents
- Various docs-build-system fixes
- Ongoing work with the Chinese, Portuguese, and Japanese
translations
...and lots of typo fixes, grammar tweaks, etc"
