Subject: [PATCH] init: check printed flag to skip printing message
Date: Thu, 8 Mar 2012 15:44:16 -0800 [thread overview]
Message-ID: <1DD7BFEDD3147247B1355BEFEFE4665237994F30F4@HQMAIL04.nvidia.com> (raw)
In-Reply-To: <1DD7BFEDD3147247B1355BEFEFE4665237994F30EF@HQMAIL04.nvidia.com>
Otherwise the 'Calibration skipped' message gets printed everytime a CPU is
hotplugged in, cluttering console for systems that frequently hotplug CPUs.
