Subject: [patch 01/37] x86/smpboot: Cleanup topology_phys_to_logical_pkg()/die()
Date: Sat, 15 Apr 2023 01:44:14 +0200 (CEST) [thread overview]
Message-ID: <20230414232309.261127575@linutronix.de> (raw)
In-Reply-To: 20230414225551.858160935@linutronix.de
Make topology_phys_to_logical_pkg_die() static as it's only used in
smpboot.c and fixup the kernel-doc warnings for both functions.
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
