commit: b9e95c5dd1134d35b6c9aeaa3967ab5b3945ba73 [371/385] mm, mpx: add "vm_flags_t vm_flags" arg to do_mmap_pgoff()
config: microblaze-nommu_defconfig (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 b9e95c5dd1134d35b6c9aeaa3967ab5b3945ba73
  # save the attached .config to linux build tree
  make.cross ARCH=microblaze
