From: Chuansheng Liu <chuansheng.liu@intel.com>
Currently, CPUIDLE_STATE_MAX has been defined as 10 in the cpuidle head file,
and max_cstate = CPUIDLE_STATE_MAX – 1, so 9 is the right maximum depth of C-state.
This change is reflected in one place of the kernel-param file,
but not in the other place where I suggest changing.
