From 6be4ec29685c216ebec61d35f56c3808092498aa Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 26 Feb 2024 12:07:31 +0100 Subject: [PATCH] x86/apic: Build the x86 topology enumeration functions on UP APIC builds too These functions are mostly pointless on UP, but nevertheless the 64-bit UP APIC build already depends on the existence of topology_apply_cmdline_limits_early(), which caused a build bug, resolve it by making them available under CONFIG_X86_LOCAL_APIC, as their prototypes already are.
