thanks a lot for information! just was wondering which branch contains the fixes?

I ask this because we still have some bisect results pointing the commits in
  mmunstable
  mmunstable2
  mmunstable3
branches in https://github.com/alexshi/linux.git

are they still useful? if they are out-of-date branches, we won't send reports
to you upon them. thanks
