There were many. You can read about what was done here:

https://lwn.net/Articles/484932/

The original is here:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ccd49c2391773ffbf52bb80d75c4a92b16972517

But more were added.

But that is back in 3.3, so 3.10 has all the required updates.
