Sorry, looks like I dropped the first line of the error messages:

arch/x86/built-in.o: In function `kvm_smp_prepare_boot_cpu':
kvm.c:(.init.text+0xad38): undefined reference to `kvm_register_clock'

from arch/x86/kernel/kvm.c:

#ifdef CONFIG_SMP
static void __init kvm_smp_prepare_boot_cpu(void)
{
	WARN_ON(kvm_register_clock("primary cpu clock"));
	kvm_guest_cpu_init();
	native_smp_prepare_boot_cpu();
}

so it looks like you are correct...
