[PATCH 2.6.13-rc1 11/11] mm: manual page migration-rc4 -- N1.2-add-nodemap-to-try_to_migrate_pages-call.patch

[Ray Bryant <raybry@sgi.com>]

Manual page migration adds a nodemap arg to try_to_migrate_pages().
The nodemap specifies where pages found on a particular node are to
be migrated.  If all you want to do is to migrate the page off of
the current node, then you specify the nodemap argument as NULL.

Add the NULL to the try_to_migrate_pages() invocation.

This patch should be added to the Memory Hotplug series after patch
N1.1-pass-page_list-to-steal_page.patch (for 2.6.12-rc5-mhp1).
