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.
