Subject: [patch V4 01/37] x86/smpboot: Cleanup topology_phys_to_logical_pkg()/die()
Date: Fri, 12 May 2023 23:06:58 +0200 (CEST)	[thread overview]
Message-ID: <20230512205255.493750666@linutronix.de> (raw)
In-Reply-To: 20230512203426.452963764@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>
