The revert is completely irrelevant to this change, really. The reference
is just confusing.

See previous mails ....

Let me give you another changelog example:

Subject: acpi/processor: Check for duplicate processor ids at hotplug time

  The check for duplicate processor ids happens at boot time based on the
  ACPI table contents, but the final sanity checks for a processor happen
  at hotplug time.

  At hotplug time, where the physical information is available, which might
  differ from the ACPI table information, a check for duplicate processor
  ids is missing.

  Add it to the hotplug checks and rename the function so it better
  reflects its purpose.

Hmm?

Please keep the acpi_ prefix. acpi_duplicate_processor_id().
