Add an ->enter_freeze callback routine, acpi_idle_enter_freeze(), to the ACPI cpuidle driver and point ->enter_freeze to it for all the C2-type and C3-type states that don't need to fall back to C1 (which may be halt-induced and that will re-enable interrupts on exit from idle, which ->enter_freeze cannot do).
