Hi Thorsten, sorry for delay in reply.
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.
