I don't think the patch is doing the right thing to deal with accounted time.

Example:

Round1: 5 seconds
1) 2s in P1
2) 3s in P0

Round2: 5 seconds
1) 3s in P0
2) 2s in P1

Here, in the second round, accounted time is apparantly for P0, but
cpu_pow->current_pstate is P1. So the suggested patch is still wrong.
