I have just created since-3.12 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v3.12 tag in Linus tree and mmotm-2014-02-05-15-56. I have pulled some cgroup wide changes from Tejun as well but cgroupfs->kernfs changes are not there yet. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The current shortlog says: Alex Williamson (1): intel-iommu: fix off-by-one in
