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")
