Thanks but to help my work could you please do this in patch 4 in my
series and send a v4 to that one patch also not reverting my changes just
changing what the review asked for, so I don't have to manually apply
changes from this series to mine which is what supposed to be committed as
it has all needed patches as aked by the PPC maintainer to make it easy to
follow its status? Also replace the assert with a comment as I've asked.
If you don't want to do that way I'll fold this in in the next version
after waiting for some more review comments so I can do a respin with all
needed chaages but doing it this way is not very helpful of you.
