Subject: [patch 18/58] x86/apic: Remove check_phys_apicid_present()
Date: Tue, 18 Jul 2023 01:15:02 +0200 (CEST) [thread overview]
Message-ID: <20230717223224.147988474@linutronix.de> (raw)
In-Reply-To: <20230717223049.327865981@linutronix.de>
The only silly usage site is gone. Remove the gunk which was even outright
wrong in the bigsmp_32 case which returned true unconditionally.
