It's expected (unfortunately). If we have SMP compiled kernel
we still rely on apic_read heavily. Since for fake'ed apic
we just return 0 for any reading I suspect we could just drop
WARN_ON_ONCE for native_apic_read_dummy. Yinghai?

(well, actually we should clean up callees but it would require
 some effort)
