commit: 25d3db7600b87a41593f31a69b761cb2514dd4cc [5613/5750] mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
config: arm-allmodconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 6.1.1-9) 6.1.1 20160705
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 25d3db7600b87a41593f31a69b761cb2514dd4cc
