On s390 I get this:

mm/page_cgroup.c: In function 'init_section_page_cgroup':
mm/page_cgroup.c:111: error: implicit declaration of function 'vmalloc_node'
mm/page_cgroup.c:111: warning: assignment makes pointer from integer without a cast
mm/page_cgroup.c: In function '__free_page_cgroup':
mm/page_cgroup.c:140: error: implicit declaration of function 'vfree'
make[1]: *** [mm/page_cgroup.o] Error 1
