/*

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. There is no functional change introduce by that patch.
