I have posted a v3 on the kvm-list:
http://www.spinics.net/lists/kvm/msg76955.html

I am carrying the above two patches(with one fix) in my series as well
for completeness. 

I have picked up the patches from PeterZ's "Unify TLB gather
implementations -v3"
http://article.gmane.org/gmane.linux.kernel.mm/81278

Nikunj
