I had to do one step back and update my development setup, in order to prevent rebase process breaking: created script to use crosstool [1] to test my future backports on all platforms and make sure to search follow-up fixes for the patch I'm porting, found kernel.dance [2] for it. Now I'm trying to reproduce issue mentioned in follow-up fix [3] to have clear red/green test results. I think I should be able to send tested fixes in next 2 weeks.
