Subject: Re: [PATCH 06/10] x86, mce: make mce_log buffer to per-CPU

In general it is not; there are exceptions for cases where either the original patch needs to be significantly modified to apply to the current codebase, or because it would cause breakage.

In those cases, use the tag Originally-by:.
