    Subject[PATCH 3.16 238/410] powerpc/pseries: Add empty update_numa_cpu_lookup_table() for NUMA=n
    3.16.57-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Corentin Labbe <clabbe@baylibre.com>

    commit c1e150ceb61e4a585bad156da15c33bfe89f5858 upstream.

    When CONFIG_NUMA is not set, the build fails with:

    arch/powerpc/platforms/pseries/hotplug-cpu.c:335:4:
    error: déclaration implicite de la fonction « update_numa_cpu_lookup_table »

    So we have to add update_numa_cpu_lookup_table() as an empty function
    when CONFIG_NUMA is not set.

    Fixes: 1d9a090783be ("powerpc/numa: Invalidate numa_cpu_lookup_table on cpu remove")
