Subject: [patch V3 09/22] x86/mpparse: Provide separate early/late callbacks
Date: Tue, 13 Feb 2024 22:05:03 +0100 (CET)	[thread overview]
Message-ID: <20240212154639.370491894@linutronix.de> (raw)
In-Reply-To: 20240212154529.402604963@linutronix.de

From: Thomas Gleixner <tglx@linutronix.de>

The early argument of x86_init::mpparse::get_smp_config() is more than
confusing. Provide two callbacks, one for each purpose.
