From cc57637b0b015fb5d70dbbec740de516d33af07d Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Thu, 29 Jun 2006 02:24:27 -0700 Subject: [PATCH] solve config broken: undefined reference to `online_page' Memory hotplug code of i386 adds memory to only highmem. So, if CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set. Otherwise, it causes compile error. In addition, many architecture can't use memory hotplug feature yet. So, I introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG.
