Not really a comment on this patch, but the diffstat above made me
suspect that you have lots of duplicates here...  Does it *really* make
sense to maintain syncronized copies of these rather large header files,
just because a total of 3 lines are different (not counting the
unneccessary header diff and the assumed unwanted whitespace diff)?
