Hi Manish,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: microblaze-allmodconfig (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 fddd56febc638207706ef56cd993cbc73b59544e
  # save the attached .config to linux build tree
  make.cross ARCH=microblaze
