There's one corner case need to be fixed: !cpuidle_ops[cpu].init. patch1 tries to address this corner case.
patch2 tries to improve arm_cpuidle_suspend() a bit by moving .suspend check into arm_cpuidle_read_ops(). Since v3: - rebased on 4.7-rc1 Since v2: - add back patch1. Since v1: - drop patch1, I.E "ARM: cpuidle: fix !cpuidle_ops[cpu].init case during init", because there may be platforms which doesn't need the init member at all. - adopt Daniel's suggestion to move the cpuidle_ops.suspend check to arm_cpuidle_read_ops().
