Emphasis on should :)

But this series is a major step forward and I decided to merge the first
lot:

I fixed up #0004 (including Borislavs comments) and polished some of the
changelogs a bit.

This reduces the size of the series and prevents that these parts get
[un]intentionally fat fingered once again.

I intentionally left out the documentation patch as that one needs to be
updated when you address the max closid issues.

Please work against tip x86/cache from now on.

The remaining issues are not that big, so I think we are really close.

Thanks
