Ingo, can we proceed without coverting this assembly to C?
I'm committed to convert it to C later if we'll find reasonable solution
to the issue.
We're pretty late into release cycle. It would be nice to give the whole
thing time in tip/master and -next before the merge window.
Can I repost part 4?
