Subject[PATCH AUTOSEL 4.14 12/46] powerpc/pseries: Add empty update_numa_cpu_lookup_table() for NUMA=n
Date
From: Corentin Labbe <clabbe@baylibre.com>

[ Upstream 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")
