I have just created since-3.17 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v3.17 tag in Linus tree and mmotm-2014-10-15-16-57. I have pulled some cgroup wide and percpu changes from Tejun which were targeted at 3.18 to help memcg dependencies. 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: Akinobu Mita (4): vfs: make guard_bh_eod() more generic vfs: guard end of device for mpage interface block_dev: implement readpages() to optimize sequential read cma: make default CMA area size zero for x86 Andrew Morton (9): mm/slab_common.c: suppress warning include/linux/migrate.h: remove migrate_page #define mm/mmap.c: clean up CONFIG_DEBUG_VM_RB checks mm/debug.c: use pr_emerg() mm-memcontrol-lockless-page-counters-fix mm-memcontrol-lockless-page-counters-fix mm-compaction-simplify-deferred-compaction-fix mm-introduce-do_shared_fault-and-drop-do_fault-fix-fix do_shared_fault(): check that mmap_sem is held Andrey Vagin (1): ipc: always handle a new value of auto_msgmni Aneesh Kumar K.V (2): mm/gup.c: update generic gup implementation to handle hugepage directory arch/powerpc: switch to generic RCU get_user_pages_fast Anton Blanchard (2): mm/page_alloc.c: convert boot printks without log level to pr_info powerpc: Enable DCACHE_WORD_ACCESS on ppc64le Baoquan He (1): fs/proc/kcore.c: don't add modules range to kcore if it's equal to vmcore range Chao Yu (1): zbud: avoid accessing last unused freelist Christoph Lameter (2): slub: disable tracing and failslab for merged slabs vmstat: on-demand vmstat workers V8 Cyrill Gorcunov (4): mm: introduce check_data_rlimit helper mm: use may_adjust_brk helper prctl: PR_SET_MM -- factor out mmap_sem when updating mm::exe_file prctl: PR_SET_MM -- introduce PR_SET_MM_MAP operation Dan Streetman (1): zsmalloc: simplify init_zspage free obj linking David Rientjes (3): mm: rename allocflags_to_migratetype for clarity mm, compaction: pass gfp mask to compact_control mm, thp: fix collapsing of hugepages on madvise Davidlohr Bueso (1): m68k: call find_vma with the mmap_sem held in sys_cacheflush() Dongsheng Yang (1): cgroup: fix a typo in comment.
