Rafael, Viresh, any thoughts on picking up patches 2-8 from this series
for 3.12?

From the discussions on this thread so far, there are no pending issues:
Toralf verified that these patches work fine on his system, as he mentioned
above, and Tianyu Lan independently tested this patchset and found no
issues with them. Also, Viresh analyzed the refcounting used in the patches
and we came to the conclusion that there is no problem with them either.
