https://git.kernel.org/linus/e3cc268fe4a0ad1cbefbc53cee35c80281e609b8 seems relevant, although I do not fully understand it. One thing that stood out for me is the check `expose_physicals > 0` instead of `expose_physicals != 0`. But that commit exists since 2.6.35 ... This very much looks like an upstream kernel issue and therefor it's better to bring it to the attention of those maintainers.
