Subject: [patch V2 10/22] x86/mpparse: Prepare for callback separation
Date: Tue, 23 Jan 2024 14:10:18 +0100 (CET) [thread overview]
Message-ID: <20240117124902.992663226@linutronix.de> (raw)
In-Reply-To: 20240117124704.044462658@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
In preparation of splitting the get_smp_config() callback, rename
default_get_smp_config() to mpparse_get_smp_config() and provide an early
and late wrapper.
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
