Have you tried to use coccinelle? As I have said, it's not a silver bullet
(yet), and it's just impossible to handle such a stuff in fully automated
mode. There are special cases that should be handled manually, and doing
them over and over again is much worse than even an endless merging.

And I still don't see an answer to the simplest possible question: why
(F|W)VARs are so bad but (B|K)VARs are OK?
