As this mmotm tree is based on the fresh new 3.8 I have created since-3.8 branch for the mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). Same as before this branch contains all mm patches based on v3.8 tag and it will track the next mmot[ms] trees without any rebases. since-3.7 branch is now obsolete. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347).
