According to your overall comments, most concerning part you have right now
is paranoid entry and ptrace legacy support. (correct me if I'm wong)
Design-wise, I think they're major changes -- I can follow-up with 
a summary if you want. I responded about paranoid entry. ptrace
legacy support is simply new that never before AFAIK.

Last week, I don't have any major issue at all. I don't know what major
issues you saw. Most likely it is just silly rebase issue I bet.
