Which makes the code fit within the rest of the x86_ops functions. Acked-by: Suresh Siddha <suresh.b.siddha@intel.com> [v1: Changed x86_apic -> x86_ioapic per Yinghai Lu <yinghai@kernel.org> suggestion] [v2: Rebased on tip/x86/urgent and redid to match Ingo's syntax style] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
