Since we didn't come to a conclusion on how should we attempt clearing 10-bit tags and Atomic Op Requestor, I held on preparing v3. https://lore.kernel.org/all/cc36bb5b-6a4a-258b-6707-4d019154e019@amd.com/ But I can go ahead and send v3 for just the first patch, https://lore.kernel.org/all/8ab986f2-6aa5-401a-aa21-e8b21f68eaad@amd.com/ and wait on Lukas for 10-bit tag issue.
