Hi,

[auto build test ERROR on next-20160520]
[cannot apply to tip/x86/core net-next/master v4.6-rc7 v4.6-rc6 v4.6-rc5 v4.6]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

config: blackfin-TCM-BF537_defconfig (attached as .config)

        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree

Note: the linux-review/Vladimir-Davydov/mm-remove-pointless-struct-in-struct-page-definition/20160523-182939 HEAD 08a247942f52ec5444ba2a0d3c951358640eccf5 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):

   fs/built-in.o: In function `anon_pipe_buf_steal':
>> fs/pipe.c:(.text+0x7304): undefined reference to `memcg_kmem_uncharge'
