Subject: [PATCH] memory-hotplug: mm/Kconfig: move auto selects from MEMORY_HOTPLUG to MEMORY_HOTREMOVE as needed
Date: Fri, 18 Jan 2013 15:54:36 +0800	[thread overview]
Message-ID: <1358495676-4488-1-git-send-email-linfeng@cn.fujitsu.com> (raw)

Since we have 2 config options called MEMORY_HOTPLUG and MEMORY_HOTREMOVE
used for memory hot-add and hot-remove separately, and codes in function
register_page_bootmem_info_node() are only used for collecting infomation
for hot-remove(commit 04753278), so move it to MEMORY_HOTREMOVE.

Besides page_isolation.c selected by MEMORY_ISOLATION under MEMORY_HOTPLUG
is also such case, move it too.
