I will acked-by and push your patch, it will be an easy "first commit". If 
I do something wrong during the process, please tell me.

Thanks for this precision, I understood this, and I will not push without

Thanks a lot for all your reviews!

Thanks for the tip, I will do this!

Perfect for the patches 1..9, it will be a very nice step forward and will 
reduce my conflicts a lot with the rest of my work!

For this, how should I do? Commit the series and wait for the bot results? 
Run tests on my computer (I only have a x86 VM)? Is there some doc 
somewhere?

Thanks a lot,
