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.
Changes from v1 to v2: * Updated the change log and patch as suggested by Thomas Gleixner.
