[RFC][PATCH 10/12] memory hotplug: call setup_per_zone_pages_min after hotplug

[Dave Hansen <haveblue@us.ibm.com>]

From: IWAMOTO Toshihiro <iwamoto@valinux.co.jp>
> I found the tests does not work well with Dave's patchset.
> I've found the followings:
> 
> 	- setup_per_zone_pages_min() calls should be added in
> 	   capture_page_range() and online_pages()
> 	- lru_add_drain() should be called before try_to_migrate_pages()

The following patch deals with the first item.
