Thanks.

note: my patch isn't full revert too. Commit d899bf7b introduced two
feature (btw, I don't like one patch have two feature).

 1) Add the annotattion of [thread stack: xxxx] mark to
    /proc/{pid}/task/{tid}/maps.
 2) Add StackUsage field to /proc/{pid}/status.

I only revert (2), because I haven't seen (1) cause regression.
