commit: ec53bfbca2559623d146321f8b3da4ec65379fff [43/86] powerpc/vdso64: Switch from
__get_datapage() to get_datapage inline macro

compiler: powerpc64-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O
~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout ec53bfbca2559623d146321f8b3da4ec65379fff
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=powerpc

Note: the linuxppc/next-test HEAD a0e12ec27095fc3f3c3d94c86fccf08ffb58d9de builds fine.
It only hurts bisectibility.
