From: Andi Kleen <a...@linux.intel.com>
Since 3b3eb0445 running perf stat on a system without
backend-stalled-cycles spits out ugly warnings by default. Since that is quite
common, make the message a debug message only. We know
anyways that the counter wasn't read by the normal <unsupported>
output.
