Merge branch 'for-next/faultaround' into for-next/core

Initialise prefaulted PTEs as 'old' for arm64 when hardware access-flag
updates are supported, which drastically improves vmscan performance.

* for-next/faultaround:
  mm: filemap: Fix microblaze build failure with 'mmu_defconfig'
  mm/nommu: Fix return type of filemap_map_pages()
  mm: Mark anonymous struct field of 'struct vm_fault' as 'const'
  mm: Use static initialisers for immutable fields of 'struct vm_fault'
  mm: Avoid modifying vmf.address in __collapse_huge_page_swapin()
  mm: Pass 'address' to map to do_set_pte() and drop FAULT_FLAG_PREFAULT
  mm: Move immutable fields of 'struct vm_fault' into anonymous struct
  arm64: mm: Implement arch_wants_old_prefaulted_pte()
  mm: Allow architectures to request 'old' entries when prefaulting
  mm: Cleanup faultaround and finish_fault() codepaths
