Well, I discussed that before with Arjan and he said he would maintain CPUidle if Len didn't have the time, but it seems he didn't expect that there would be a lot of work on it in the near future. So, I suggest that if neither Len nor Arjan reappear shortly, people can send CPUidle patches to me. Thanks, Rafael
