From: Ralph Campbell <rcampbell@nvidia.com>

I was debugging with v5.1.0-rc1 and while booting I hit a
kernel BUG at arch/x86/mm/physaddr.c:27
which I fixed with the following patch but now I can't seem
to reproduce the exact setup that triggered it.
Still, it seems like a valid problem and maybe my difficulty
in reproducing it explains why others haven't seen it earlier.
