You may see I was adding the missing Copyright of files created by 
Nvidia developers in past. I have not evaluated the copyright value of 
the contents added in the initial check-in. As suggested, I plan to drop 
this patch in any further revisions of patches from this list.

I had emailed the authors(outside Nvidia) asking about additional 
Copyright to add, but did not get response from all. One author was fine 
with adding the Nvidia Copyright. I see now Copyright backwards needs us 
to follow above approach. As mentioned above in my reply to your 
comments I am planning to drop this patch if sending subsequent 
revisions in this patch list.

Thanks for the inputs.
