commit: cc63e257a83a56646e129827378db2184690f675 [326/458] kernel.h: implement DIV_ROUND_CLOSEST_ULL
config: microblaze-allyesconfig (attached as .config)
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 cc63e257a83a56646e129827378db2184690f675
  # save the attached .config to linux build tree
  make.cross ARCH=microblaze
