Subject: since-3.8 branch opened for mm git tree (was: mmotm 2013-02-19-17-20
 uploaded)

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).

The current shortlog says (I have squashed all -fix patches into their
