Add a flag to the perf mem data struct to signal that a request caused a
cache-to-cache transfer of a line from a peer of the requestor and
wasn't sourced from a lower cache level.  The line being moved from one
peer cache to another has latency and performance implications. On Arm64
Neoverse systems the data source can indicate a cache-to-cache transfer
but not if the line is dirty or clean, so instead of overloading HITM
define a new flag that indicates this type of transfer.

Was this already merged on the ARM kernel tree?

No, I don't think this patch has been merged on Arm kernel tree.  I searched
Arm and Arm64 git repos, none of them has merged this patch.

Do you want us to resend the patch set for adding tags?

I use b4 and it should collect Reviewed-by, Acked-by, etc tags, for
instance, if I use the message-id in your message:
