Because that wouldn't work -- the kernel only knows how to do atomic 32-bit accesses to config space (and for some config methods, you can't do 64-bit accesses). It would be a fairly big effort to make a 64-bit access atomic. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
