It was in a patch that exempted AMD processors submitted by an AMD employee that the hint as to the root cause was found.
So the patch, already accepted, will do as you suggest.
Important: at least accordingly to Intel, AMD is also affected:

Neither Intel, nor your linked article says AMD is affected. Some ARM processors are. But AMD has specificly denied it. -- Sent from my Android phone with K-9 Mail.

There are multiple exploits. One apparently relies on what can be considered hardware design and so it is possible that AMD is not vulnerable. Others simply (ab-)use speculative instruction execution/branch prediction and were PoC for Intel, AMD and ARM. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
