[PATCH v3 0/4] cpufreq: Fixes and cleanups related to CPUFREQ_ETERNAL

[Rafael J. Wysocki]

Hi All,

This is an update of

https://lore.kernel.org/linux-pm/8605612.T7Z3S40VBb@rafael.j.wysocki/

The update is due because of some changes in the first patch (involving Rust)
and in the second patch (function rename).  It is v3 because a v2 of the
third patch was sent after the v1.

The original cover letter quoted below still applies:

 The first patch in this series is meant to address the failure discussed in

 https://lore.kernel.org/linux-pm/20250922125929.453444-1-shawnguo2@xxxxxxxx/

 but in a different way than proposed by Shawn.

 The second one is a CPPC cpufreq driver fix preventing it from using an
 overly large transition delay in the cases when that delay cannot be
 obtained from the platform firmware.

 Patch [3/4] makes CPPC use a specific symbol instead of CPUFREQ_ETERNAL for
 signaling error conditions while attempting to retrieve a transition latency
 value from the platform firmware.

 The last patch removes CPUFREQ_ETERNAL (which has no users any more) from
 cpufreq, including all references to it in cpufreq documentation.

Thanks!
