X-Git-Tag: omap-for-v3.10/dt-fixes-for-merge-window~110^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=587ff8c4eab1587044e69156f997e9d1d3b07709;p=pandora-kernel.git x86/mm/hotplug: Put kernel_physical_mapping_remove() declaration in CONFIG_MEMORY_HOTREMOVE 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.
