Subject: [PATCH] powerpc/pseries: Add empty update_numa_cpu_lookup_table() for

 NUMA=n

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

References: bsc#1181674 ltc#189159

Patch-mainline: v4.16-rc2

Git-commit: c1e150ceb61e4a585bad156da15c33bfe89f5858

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")
