Hi Arnaldo, I hope you would be satisified with this weeks pull request. In this patchset, we totally get rid of dummy events by utilizing Namhyung's newest perf probing API. Patch 1-6 are different from previous patchset. Plase have a look. Due to some reason I can't access my kernel.org account in my company today, so I reuse my github repository. I'll update my kernel.org tree at home. I'll have a long vacation from Sept. 24. I hope I can discuss with you with my private email. However, It seems impossible to modify code and test until Oct. 7. If you find some small problem, could you please help me fix them? Thank you.
