Hello,

We still have this series flagged as "new" in powerpc's patchwork.

It is still of interest ?

Patch 1 applies but patch 2 hardly conflicts in init/main.c

So I'll flag it as "change requested", fell free to resubmit if still 
relevant.

Or if you think that's still required but don't plan to handle it, tell 
me and I'll open an issue in our issue board so that we don't loose history.

Thanks
Christophe
