Merge branch 'akpm' (Andrew's patch-bomb)
Merge patches from Andrew Morton: "A few misc things and very nearly all of the MM tree. A tremendous amount of stuff (again), including a significant rbtree library rework." * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (160 commits) sparc64: Support transparent huge pages. mm: thp: Use more portable PMD clearing sequenece in zap_huge_pmd(). mm: Add and use update_mmu_cache_pmd() in transparent huge page code. sparc64: Document PGD and PMD layout. sparc64: Eliminate PTE table memory wastage. sparc64: Halve the size of PTE tables sparc64: Only support 4MB huge pages and 8KB base pages. memory-hotplug: suppress "Trying to free nonexistent resource <XXXXXXXXXXXXXXXX-YYYYYYYYYYYYYYYY>" warning mm: memcg: clean up mm_match_cgroup() signature mm: document PageHuge somewhat mm: use %pK for /proc/vmallocinfo mm, thp: fix mlock statistics mm, thp: fix mapped pages avoiding unevictable list on mlock memory-hotplug: update memory block's state and notify userspace memory-hotplug: preparation to notify memory block's state at memory hot remove mm: avoid section mismatch warning for memblock_type_name make GFP_NOTRACK definition unconditional cma: decrease cc.nr_migratepages after reclaiming pagelist CMA: migrate mlocked pages kpageflags: fix wrong KPF_THP on non-huge compound pages ...
