Thanks for your merge!

I tested your cleaning patch, and this has no problem.
So I'll queue this with next patch series post.

And I have a question.
In tools/perf/command-list.txt, there is the word "mainporcelain".
What does this mean?

Of course I searched this word on my dictionary, but cannot got an answer.
I'm preparing the initial document for perf-bench.
Can I add perf-bench with mainporcelain to command-list.txt?
