Changeset 11282:bf2ca8cda251 --------------------------- mem: Only forward the non-writable flag if truly needed This patch ensures a cache does not forward the non-writable flag from a CPU-side request unless it has to. Thus, we avoid being overly conservative and returning non-writable responses even when we know that the response is the only writable copy in the system (the request was sent out with NeedsWritable set).
