Subject: [patch V2 02/22] x86/platform/ce4100: Dont override x86_init.mpparse.setup_ioapic_ids
Date: Tue, 23 Jan 2024 14:10:05 +0100 (CET) [thread overview]
Message-ID: <20240117124902.469526593@linutronix.de> (raw)
In-Reply-To: 20240117124704.044462658@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
There is no point to do that. The ATOMs have an XAPIC for which this
function is a pointless exercise.
