I have just created since-3.14 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v3.14 tag in Linus tree and mmotm-2014-04-15-16-14. I have pulled some cgroup wide changes from Tejun and Pekka's slab changes. 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: Alex Thorlton (3): mm: revert "thp: make MADV_HUGEPAGE check for mm->def_flags" mm, thp: add VM_INIT_DEF_MASK and PRCTL_THP_DISABLE exec: kill the unnecessary mm->def_flags setting in load_elf_binary() Andrew Morton (9): drivers/lguest/page_tables.c: rename do_set_pte() mips-export-flush_icache_range-fix mm-hugetlbfs-fix-rmapping-for-anonymous-hugepages-with-page_pgoff-v3-fix pagewalk-update-page-table-walker-core-fix-end-address-calculation-in-walk_page_range-fix pagemap-redefine-callback-functions-for-page-table-walker-fix pagewalk-remove-argument-hmask-from-hugetlb_entry-fix-fix mm-introduce-do_shared_fault-and-drop-do_fault-fix-fix mm/compaction.c:isolate_freepages_block(): small tuneup do_shared_fault(): check that mmap_sem is held Andrey Vagin (1): proc: show mnt_id in /proc/pid/fdinfo Bob Liu (1): mm: rmap: don't try to add an unevictable page to lru list Catalin Marinas (1): arm64: Extend the PCI I/O space to 16MB Choi Gi-yong (1): mm: fix 'ERROR: do not initialise globals to 0 or NULL' and coding style Christoph Lameter (8): percpu: add raw_cpu_ops mm: use raw_cpu ops for determining current NUMA node modules: use raw_cpu_write for initialization of per cpu refcount. net: replace __this_cpu_inc in route.c with raw_cpu_inc slub: use raw_cpu_inc for incrementing statistics vmstat: use raw_cpu_ops to avoid false positives on preemption checks percpu: add preemption checks to __this_cpu ops vmscan: reclaim_clean_pages_from_list() must use mod_zone_page_state() Colin Cross (1): dma-buf: avoid using IS_ERR_OR_NULL Cyrill Gorcunov (3): mm: softdirty: make freshly remapped file pages being softdirty unconditionally mm: softdirty: don't forget to save file map softdiry bit on unmap mm: softdirty: clear VM_SOFTDIRTY flag inside clear_refs_write() instead of clear_soft_dirty() Dave Hansen (2): mm: slab/slub: use page->list consistently instead of page->lru drop_caches: add some documentation and info message Dave Jones (1): slub: fix leak of 'name' in sysfs_slab_add Dave Young (1): x86/mm: sparse warning fix for early_memremap David Howells (2): asm/system.h: clean asm/system.h from docs asm/system.h: um: arch_align_stack() moved to asm/exec.h David Rientjes (9): mm, compaction: ignore pageblock skip when manually invoking compaction mm, hugetlb: mark some bootstrap functions as __init mm, compaction: avoid isolating pinned pages fork: collapse copy_flags into copy_process mm, mempolicy: rename slab_node for clarity mm, mempolicy: remove per-process flag res_counter: remove interface for locked charging and uncharging mm, compaction: determine isolation mode only once arch/x86/mm/kmemcheck/kmemcheck.c: use kstrtoint() instead of sscanf() Davidlohr Bueso (7): mm, hugetlb: fix race in region tracking mm, hugetlb: improve page-fault scalability mm/memory.c: update comment in unmap_single_vma() mm: per-thread vma caching mm: fix CONFIG_DEBUG_VM_RB description mm,vmacache: add debug data mm,vmacache: optimize overflow system-wide flushing Djalal Harouni (2): procfs: make /proc/*/{stack,syscall,personality} 0400 procfs: make /proc/*/pagemap 0400 Emil Medve (1): memblock: use for_each_memblock() Eric W.
