    Correct build failure for powerpc/pseries builds with CONFIG_SMP not defined.
    The function cpu_sibling_mask has no meaning (or definition) when CONFIG_SMP
    is not defined. Additionally, the updating of NUMA affinity for a CPU in a UP
    system doesn't really make sense.
    This patch ifdef's out the code making the affinity updates for PRRN events to
    fix the following build break.
    arch/powerpc/mm/numa.c: In function ‘stage_topology_update’:
    arch/powerpc/mm/numa.c:1535: error: implicit declaration of function ‘cpu_sibling_mask’
    arch/powerpc/mm/numa.c:1535: warning: passing argument 3 of ‘cpumask_or’ makes pointer from integer without a cast
    make[1]: *** [arch/powerpc/mm/numa.o] Error 1
