The cut'n'paste doesn't include the renames which the patch below does
(i..e. it should be a more accurate representation of lines changed by
ignoring the lines moved).

This was based on Gustova Padovan's destaged sync tree, so all the
Android changes should be inside drivers/dma-buf/*sync*

I was using grep to find all users of struct fence and callers of
fence_*() so I don't think I missed any drivers/staging/ - and obviously
this will have to repeated closer to the flag day.
