From 587ff8c4eab1587044e69156f997e9d1d3b07709 Mon Sep 17 00:00:00 2001 From: Tang Chen Date: Mon, 15 Apr 2013 17:46:46 +0800 Subject: [PATCH] x86/mm/hotplug: Put kernel_physical_mapping_remove() declaration in CONFIG_MEMORY_HOTREMOVE MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit kernel_physical_mapping_remove() is only called by arch_remove_memory() in init_64.c, which is enclosed in CONFIG_MEMORY_HOTREMOVE. So when we don't configure CONFIG_MEMORY_HOTREMOVE, the compiler will give a warning: warning: ‘kernel_physical_mapping_remove’ defined but not used So put kernel_physical_mapping_remove() in CONFIG_MEMORY_HOTREMOVE.
