Later commits will cause objtool to warn about static calls being used in .noinstr sections in order to safely defer instruction patching IPIs targeted at NOHZ_FULL CPUs. x86_idle is updated in: o xen_set_default_idle() <- __init xen_arch_setup() o __init select_idle_routine() IOW purely init context, and can thus be marked as __ro_after_init.
