Note that's the wrong workflow. We dont rebase Git trees really just because 'something needs to be changed' - we make sure all commits make sense, we fix bugs and append new changes to the end. That results in a far better end result than a constant rebasing workflow. See various mails from Linus on lkml about this topic.

I'll wait for Andreas's next version of the patch. Feel free to carry the interim version - just please dont crash the x86 bootup ;-) Ingo
