commit: e91caeedb603eff09af9e4840bde1d3dcf02fb00 [187/255] clone: support passing tls argument via C rather than pt_regs magic
config: s390-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 e91caeedb603eff09af9e4840bde1d3dcf02fb00
  # save the attached .config to linux build tree
  make.cross ARCH=s390
