Jesper Juhl 17295c88a1 memcg: use [kv]zalloc[_node] rather than [kv]malloc+memset 
In mem_cgroup_alloc() we currently do either kmalloc() or vmalloc() then
followed by memset() to zero the memory.  This can be more efficiently
achieved by using kzalloc() and vzalloc().  There's also one situation
where we can use kzalloc_node() - this is what's new in this version of
the patch.
