Hi Or,

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

url:    https://github.com/0day-ci/linux/commits/Or-Gerlitz/net-sched-cls_flower-Add-support-for-matching-on-flags/20161207-012247
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
        # save the attached .config to linux build tree
        make.cross ARCH=arm 

Note: the linux-review/Or-Gerlitz/net-sched-cls_flower-Add-support-for-matching-on-flags/20161207-012247 HEAD 591ecce02e6ed3dab17d5c45a3f7368581c596ce builds fine.
