In case you fear the rebase pain of renaming this:

1. Export entire series as patches with git format-patch.
2. sed -e 's/PDPE/PDE/g' on all the patch files
3. Import the changed patches into a new fresh branch.'

That's all. Feels really crazy the first time you do it, but after having
done this a lot with the internal branch when something random (function
name or so) changed in upstream it's a fairly simple trick to pull off ;-)

Cheers, Daniel
