Of course, feel free to grab the whole series. You'll probably need
the initial patches to set the scene for this. On their own, they are
a nice cleanup, and I trust you can write a decent commit message for
the three patches affecting mips/s390/x86.

I would normally do that myself, but my network connectivity is
reduced to almost nothing at the moment.
