Hi David,

[auto build test ERROR on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Roopa-Prabhu/net-extend-RTM_GETROUTE-to-return-fib-result/20170525-053253
config: openrisc-or1ksim_defconfig (attached as .config)
compiler: or1k-linux-gcc (GCC) 5.4.0
reproduce:
        wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=openrisc 

Note: the linux-review/Roopa-Prabhu/net-extend-RTM_GETROUTE-to-return-fib-result/20170525-053253 HEAD 083c4ee9e124d0acf29d159ced8a22cb41665a7a builds fine.
      It only hurts bisectibility.
