In the file x2apic_uv_x.c, some code is compiled conditionally depending on CONFIG_SMP. However, the file is only built, if CONFIG_X86_UV is enabled.
CONFIG_X86_UV depends on CONFIG_NUMA, which itself depends on CONFIG_SMP, so the ifdef will always evaluate to true, if the file is compiled. Thus, it is unnecessary and can be removed.
