Yes, I believe that's true based on code inspection. But I'm not aware of any
reported issues in this area before the commit listed above. So I decided to
switch the Fixes tag from what I had before (shown below). I can switch it
back if you think that's best.

Fixes: 019f34fccfd5 ("x86, MCE, AMD: Move shared bank to node descriptor")

Thanks,
