[PATCH] cell: enable pause(0) in cpu_idle
This patch enables support for pause(0) power management state for the Cell Broadband Processor, which is import for power efficient operation. The pervasive infrastructure will in the future enable us to introduce more functionality specific to the Cell's pervasive unit.
