[patch V3 29/60] x86/apic: Nuke apic::apicid_to_cpu_present()

From: Thomas Gleixner
Date: Tue Aug 01 2023 - 06:49:26 EST


This is only used on 32bit and is a wrapper around
physid_set_mask_of_physid() in all 32bit APIC drivers.

Remove the callback and use physid_set_mask_of_physid() in the code
directly,
