This looks good to me. I'll apply it to my tricore-next branch and I
will send a pull request for upstream soon. I still have some minor nit
picks (see email inlines). However, you don't have to respin -- they are
minor and I will fix them before applying, due to softfreeze being right
around the corner.

Of course. My suggestion was just in the interest of this patch series.
I'd be happy to review your proper solution.
