If anyone has any objections, please let me know. ------------------ From: Viresh Kumar [ Upstream commit 0c7f7a5150023f3c6f0b27c4d4940ce3dfaf62cc ] The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add such missing properties.
