I have just created since-4.5 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v4.5 tag in Linus tree and mmotm-2016-03-25-15-13. I have pulled cgroup changes and pkeys patches merged via tip tree. As usual mmotm trees are tagged with signed tag (finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347) The shortlog says: Aaro Koskinen (1): drivers/firmware/broadcom/bcm47xx_nvram.c: fix incorrect __ioread32_copy Alexander Kuleshov (1): mm/memblock.c: remove unnecessary memblock_type variable Alexander Potapenko (8): kasan: modify kmalloc_large_oob_right(), add kmalloc_pagealloc_oob_right() mm, kasan: SLAB support mm, kasan: add GFP flags to KASAN API arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections mm, kasan: stackdepot implementation.
