From 7a4dcb4a5de1214c4a59448a759e2e264c2c4473 Mon Sep 17 00:00:00 2001 From: Laurent Dufour Date: Wed, 5 Jul 2023 16:51:34 +0200 Subject: cpu/hotplug: Remove dependancy against cpu_primary_thread_mask The commit 18415f33e2ac ("cpu/hotplug: Allow "parallel" bringup up to CPUHP_BP_KICK_AP_STATE") introduce a dependancy against a global variable cpu_primary_thread_mask exported by the X86 code. This variable is only used when CONFIG_HOTPLUG_PARALLEL is set. Since cpuhp_get_primary_thread_mask() and cpuhp_smt_aware() are only used when CONFIG_HOTPLUG_PARALLEL is set, don't define them when it is not set. No functional change.
