Well, patches like these should be done in a way that the tooling parts
can deal with kernels with or without the kernel changes, so that older
tools work with new kernels and new tools work with older kernels.

"work" as in the previous behaviour is kept when a new tool deals with
an older kernel and an older tool would warn the user that what it needs
is not present in that kernel.

Is this the case? I just looked briefly at the patch commit logs.

If it is, then I can pick the tool ones, and the others can be submitted
to the relevant trees, at some point all will be in, kernels eventually
gets updated everywhere, ditto for the tooling, all gets well.
