Subject: [patch V2 01/38] x86/smpboot: Cleanup topology_phys_to_logical_pkg()/die()
Date: Thu, 4 May 2023 21:02:00 +0200 (CEST) [thread overview]
Message-ID: <20230504185936.367031787@linutronix.de> (raw)
In-Reply-To: 20230504185733.126511787@linutronix.de
From: Thomas Gleixner <tglx@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>
