The tegra3 and big.LITTLE architecture have different cpu latencies. This API allows to specify a different cpu latency for a specific cpu.
With the previous patches, we use the per cpuidle device states pointer, this function overrides this pointer.

Looks good... apart from the fact that the function definition says cpuidle_register_stateS and the exported symbol is cpuidle_register_state...
Cheers,
