I forgot to mention that this is observed on 3.18 android kernel fork under a
quite specific condition: EMC scaling enabled and set to the lowest freq, CPU
max freq reduced. This may cause higher latency on CPU idle enter/exit.
I couldn't reproduce this issue with the upstream kernel, guess some specific
workload is also required. Any comments? =)
