Above four are my works. All of them work now. But more job should be done to 
polish the patches. And the main part of Function Level Reset would be picked 
by linux-pci. 

Another thing is we would send out/update above patches before Sept. 28, and 
hope they can picked by 2.6.28 merge window.

Avi, what's your opinion? Of course we would work hard. :) But what's the 
deadline of merge window?

I still don't know who would do this. It's very important for VT-d real 
usable. If nobody interested in it, I would pick it up, but after Oct. 6
(after National Holiday in China).
