Subject: [PATCH 5/5] Disable MCP limit exceeded messages from Intel IPS driver

From: Andi Kleen <ak@...ux.intel.com>

On a system on the thermal limit these are quite noisy and flood the logs.
Better would be a counter anyways. But given that we don't even have
anything for normal throttling this doesn't seem to be urgent either.
