I have just created since-4.0 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v4.0 tag in Linus tree and mmotm-2015-04-23-16-38. I have pulled some cgroup wide changes from Tejun. 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: Alexander Kuleshov (1): mm/memblock.c: add debug output for
