It looks like whoever wrote this explicitly didn't want that APIC
driver used on domU:
#ifdef CONFIG_XEN_DOM0
void __init xen_init_vga(const struct dom0_vga_console_info *, size_t size);
void __init xen_init_apic(void);
#else
static inline void __init xen_init_vga(const struct dom0_vga_console_info *info,
size_t size)
{
}
static inline void __init xen_init_apic(void)
{
}
#endif
