Subject: [PATCH] powerpc: add empty update_numa_cpu_lookup_table for !CONFIG_NUMA
Date: Wed, 14 Feb 2018 12:17:47 +0000	[thread overview]
Message-ID: <1518610667-23406-1-git-send-email-clabbe@baylibre.com> (raw)

When CONFIG_NUMA is not set, build fail with:
arch/powerpc/platforms/pseries/hotplug-cpu.c:335:4: error: déclaration implicite de la fonction « update_numa_cpu_lookup_table » [-Werror=implicit-function-declaration]

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")
