Merge branch 'akpm' (patches from Andrew)
Merge yet more updates from Andrew Morton: "The rest of MM and a kernel-wide procfs cleanup. Summary of the more significant patches: - Patch series "mm/memory_hotplug: Factor out memory block devicehandling", v3. David Hildenbrand. Some spring-cleaning of the memory hotplug code, notably in drivers/base/memory.c - "mm: thp: fix false negative of shmem vma's THP eligibility". Yang Shi. Fix /proc/pid/smaps output for THP pages used in shmem. - "resource: fix locking in find_next_iomem_res()" + 1. Nadav Amit. Bugfix and speedup for kernel/resource.c - Patch series "mm: Further memory block device cleanups", David Hildenbrand. More spring-cleaning of the memory hotplug code. - Patch series "mm: Sub-section memory hotplug support". Dan Williams. Generalise the memory hotplug code so that pmem can use it more completely. Then remove the hacks from the libnvdimm code which were there to work around the memory-hotplug code's constraints. - "proc/sysctl: add shared variables for range check", Matteo Croce. We have about 250 instances of int zero; ... .extra1 = &zero, in the tree. This is a tree-wide sweep to make all those private "zero"s and "one"s use global variables. Alas, it isn't practical to make those two global integers const" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (38 commits) proc/sysctl: add shared variables for range check mm: migrate: remove unused mode argument mm/sparsemem: cleanup 'section number' data types libnvdimm/pfn: stop padding pmem namespaces to section alignment libnvdimm/pfn: fix fsdax-mode namespace info-block zero-fields mm/devm_memremap_pages: enable sub-section remap mm: document ZONE_DEVICE memory-model implications mm/sparsemem: support sub-section hotplug mm/sparsemem: prepare for sub-section ranges mm: kill is_dev_zone() helper mm/hotplug: kill is_dev_zone() usage in __remove_pages() mm/sparsemem: convert kmalloc_section_memmap() to populate_section_memmap() mm/hotplug: prepare shrink_{zone, pgdat}_span for sub-section removal mm/sparsemem: add helpers track active portions of a section at boot mm/sparsemem: introduce a SECTION_IS_EARLY flag mm/sparsemem: introduce struct mem_section_usage drivers/base/memory.c: get rid of find_memory_block_hinted() mm/memory_hotplug: move and simplify walk_memory_blocks() mm/memory_hotplug: rename walk_memory_range() and pass start+size instead of pfns mm: make register_mem_sect_under_node() static ...
