commit: 516dfd6c8353f33af29b54a4251f9130cd8b78ca [107/363] mm: change the interface for __tlb_remove_page()
config: ia64-generic_defconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 4.9.0
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 516dfd6c8353f33af29b54a4251f9130cd8b78ca
        # save the attached .config to linux build tree
        make.cross ARCH=ia64 

Note: the mel/mm-vmscan-node-lru-follow-up-v2r1 HEAD d5502746ab169a810a4adc0ec760117790e477df builds fine.
      It only hurts bisectibility.
