  zswap: use movable memory if zpool support allocate movable memory
  zpool: add malloc_support_movable to zpool_driver
  shmem: fix obsolete comment in shmem_getpage_gfp()
  mm/madvise: reduce code duplication in error handling paths
  mm: mmap: increase sockets maximum memory size pgoff for 32bits
  mm/mmap.c: refine find_vma_prev() with rb_last()
  riscv: make mmap allocation top-down by default
  mips: use generic mmap top-down layout and brk randomization
  mips: replace arch specific way to determine 32bit task with generic version
  mips: adjust brk randomization offset to fit generic version
  mips: use STACK_TOP when computing mmap base address
  mips: properly account for stack randomization and stack guard gap
  arm: use generic mmap top-down layout and brk randomization
  arm: use STACK_TOP when computing mmap base address
  arm: properly account for stack randomization and stack guard gap
  arm64, mm: make randomization selected by generic topdown mmap layout

Description:
The shrink file is written when memory should be reclaimed from
a cache. Empty partial slabs are freed and the partial list is
sorted so the slabs with the fewest available objects are used
first.
The shrink file is used to reclaim unused slab cache
memory from a cache. Empty per-cpu or partial slabs
are freed and the partial list is sorted so the slabs
with the fewest available objects are used first.
It only accepts a value of "1" on write for shrinking
the cache. Other input values are considered invalid.
Shrinking slab caches might be expensive and can
adversely impact other running applications. So it
should be used with care.
