From 4e76f4e67a106ed827ca721b4c8b622047cd2f6d Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Wed, 22 Dec 2010 17:23:47 -0800 Subject: x86, numa: Avoid compiling NUMA emulation functions without CONFIG_NUMA_EMU Both acpi_get_nodes() and amd_get_nodes() are only necessary when CONFIG_NUMA_EMU is enabled, so avoid compiling them when the option is disabled.
