I have just created since-4.13 branch in mm git tree (http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It is based on v4.13 tag in Linus tree and mmotm-2017-09-08-16-48 plus I have merged tip/x86/mm which contains 5-level page table stuff plus PCID changes and cgroup core changes in case there will be some later changes regarding memcg which would depend on those. Let me know if some other changes should be merged as well for an easier development on top of this 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: Aaron Lu (1): swap: choose swap device according to numa node Alexander Popov (1): mm/slub.c: add a naive detection of double free or corruption Alexander Potapenko (1): slub: tidy up initialization ordering Alexey Dobriyan (3): proc: uninline proc_create() treewide: make "nr_cpu_ids" unsigned cpumask: make cpumask_next() out-of-line Alexey Perevalov (1): userfaultfd: provide pid in userfault msg Andrea Arcangeli (6): userfaultfd: selftest: exercise UFFDIO_COPY/ZEROPAGE -EEXIST userfaultfd: selftest: explicit failure if the SIGBUS test failed userfaultfd: call userfaultfd_unmap_prep only if __split_vma succeeds userfaultfd: provide pid in userfault msg - add feat union mm: oom: let oom_reap_task and exit_mmap run concurrently userfaultfd: non-cooperative: closing the uffd without triggering SIGBUS Andrew Morton (2): treewide-remove-gfp_temporary-allocation-flag-fix treewide-remove-gfp_temporary-allocation-flag-checkpatch-fixes Andy Shevchenko (1): lib/hexdump.c: return -EINVAL in case of error in hex2bin() Anshuman Khandual (2): mm/memory.c: remove reduntant check for write access mm/mempolicy.c: remove BUG_ON() checks for VMA inside mpol_misplaced() Arnd Bergmann (2): fscache: fix fscache_objlist_show format processing IB/mlx4: fix sprintf format warning Arvind Yadav (5): mm/ksm.c: constify attribute_group structures mm/slub.c: constify attribute_group structures mm/page_idle.c: constify attribute_group structures mm/huge_memory.c: constify attribute_group structures mm/hugetlb.c: constify attribute_group structures Babu Moger (3): arch: define CPU_BIG_ENDIAN for all fixed big endian archs arch/microblaze: add choice for endianness and update Makefile include: warn for inconsistent endian config definition Baoquan He (1): lib/cmdline.c: remove meaningless comment Byungchul Park (1): mm/vmalloc.c: don't reinvent the wheel but use existing llist API Chris Wilson (2): mm: track actual nr_scanned during shrink_slab() drm/i915: wire up shrinkctl->nr_scanned Cyrill Gorcunov (1): tools/testing/selftests/kcmp/kcmp_test.c: add KCMP_EPOLL_TFD testing Dan Carpenter (1): lib/string.c: check for kmalloc() failure Dan Williams (1): mm, devm_memremap_pages: use multi-order radix for ZONE_DEVICE lookups Daniel Colascione (1): mm: add /proc/pid/smaps_rollup Daniel Micay (1): init/main.c: extract early boot entropy from the passed cmdline Darrick J.
