Subject: [PATCH 1/5] memcg fix numa_stat permission

commit 406eb0c9b ("memcg: add memory.numastat api for numa statistics")
 adds memory.numa_stat file for memory cgroup.  But the file permissions
 are wrong.

[kamezawa@...extal linux-2.6]$ ls -l /cgroup/memory/A/memory.numa_stat
---------- 1 root root 0 Jun  9 18:36 /cgroup/memory/A/memory.numa_stat

This patch fixes the permission as

[root@...extal kamezawa]# ls -l /cgroup/memory/A/memory.numa_stat
-r--r--r-- 1 root root 0 Jun 10 16:49 /cgroup/memory/A/memory.numa_stat
