Randconfig build by Fengguang's robot army reported:
drivers/built-in.o: In function `extlog_print':
>> acpi_extlog.c:(.text+0xcc719): undefined reference to `boot_cpu_physical_apicid'
The config had CONFIG_SMP=n so we picked up this definition from:
<asm/cpu.h>: #define cpu_physical_id(cpu) boot_cpu_physical_apicid
But boot_cpu_physical_apicid is defined in arch/x86/kernel/apic/apic.c
which is only built if CONFIG_X86_LOCAL_APIC=y.
