Hi Johannes,

It's probably a bug fix that unveils the link errors.

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head:   6b43f715b6379433e8eb30aa9bcc99bd6a585f77
commit: d530b9864073a714a6b6dcddee77c9b24074071f [4929/7613] staging: wilc1000: adjust for management frame register API changes
config: m68k-allmodconfig (attached as .config)
compiler: m68k-linux-gcc (GCC) 9.3.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout d530b9864073a714a6b6dcddee77c9b24074071f
        # save the attached .config to linux build tree
        COMPILER_INSTALL_PATH=$HOME/0day GCC_VERSION=9.3.0 make.cross ARCH=m68k 

If you fix the issue, kindly add following tag as appropriate
Reported-by: kbuild test robot <lkp@intel.com>

Note: the linux-next/master HEAD 6b43f715b6379433e8eb30aa9bcc99bd6a585f77 builds fine.
      It may have been fixed somewhere.

Is there something wrong? Surely a change in a staging wireless driver didn't cause openvswitch to gain a 64/64 bit division ...
