We currently have only one caller of mem_cgroup_select_victim_node which
is sitting in mm/vmscan.c and which is already wrapped by CONFIG_MEMCG
ifdef. Now that we have struct mem_cgroup visible outside of
mm/memcontrol.c we can move the function and its dependencies there.
This even shrinks the code size by few bytes:

   text    data     bss     dec     hex filename

I dislike this patch, because I don't see any reason why logic specific
to per memcg reclaim should live in the file representing the global
reclaim path. With such an approach you may end up with moving
mem_cgroup_low, mem_cgroup_soft_limit_reclaim, etc to vmscan.c, because
they are used only there. I don't think it's right.

Thanks,
Vladimir
