Subject: [patch v2 09/38] x86/cpu: Move logical package and die IDs into topology info
Date: Fri, 28 Jul 2023 14:12:53 +0200 (CEST) [thread overview]
Message-ID: <20230728120930.166316762@linutronix.de> (raw)
In-Reply-To: 20230728105650.565799744@linutronix.de
Yet another topology related data pair. Rename logical_proc_id to
logical_pkg_id so it fits the common naming conventions.
No functional change.
