Hi Steven,
It's probably a bug fix that unveils the link errors.

compiler: powerpc64-linux-gcc (GCC) 7.5.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross

# save the attached .config to linux build tree

I've no idea why this has been bisected to my commit. I repeated the
bisection manually and that fingered:
a55c7454a8c8 ("sched/topology: Improve load balancing on AMD EPYC systems")
which certainly looks like it could be the culprit given it introduces
the node_reclaim_distance variable.

Hi Steve,
Sorry for the inconvenience, the report is a false positive,
we are investigating the cause of the error.
