Hi Andrew,
could you add the patch bellow on top of memcg-cleanup-kmem-tcp-ifdefs.patch?
They are not directly related (that's why I didn't post it as a series)
but this one depend on the changed context (and it makes my old compiler much
happier).

Subject: [PATCH] memcg: move mem_cgroup_is_root upwards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
kmem code uses this function and it is better to not use forward
declarations for static inline functions as some (older) compilers don't
like it:
gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux)
mm/memcontrol.c:421: warning: ‘mem_cgroup_is_root’ declared inline after being called
mm/memcontrol.c:421: warning: previous declaration of ‘mem_cgroup_is_root’ was here
