    Revert "mm: avoid tail page refcounting on non-THP compound pages"
    
    This reverts commit 8d63d99a5dfbdb997d12dd3c07b2070ca723db3b.
    
    It causes in VM mapping refcount errors:
    
      page:ffffea0010a15040 count:0 mapcount:1 mapping:          (null) index:0x0
      flags: 0x8000000000008014(referenced|dirty|tail)
      page dumped because: VM_BUG_ON_PAGE(page_mapcount(page) != 0)
      ------------[ cut here ]------------
      kernel BUG at mm/swap.c:134!
