commit: b0291c3d28e83966e8b54cddd836d51afa86ac0f [8232/8750] lib/decompressors: use real out buf size for gunzip with kernel
config: mips-loongson3_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 b0291c3d28e83966e8b54cddd836d51afa86ac0f
  # save the attached .config to linux build tree
  make.cross ARCH=mips
