    fs/ext4: remove generic_file_remap_pages
    This helper was removed by ms commit d83a08db5ba6 ("mm: drop
    vm_ops->remap_pages and generic_file_remap_pages() stub").
    The helper was used for remap_file_pages syscall, which from ~v4.0
    (and in .493 kernel) uses emulation by inserting multiple VMAs,
    see ms commit c8d78c1823f4 ("mm: replace remap_file_pages() syscall
    with emulation").
    To be squashed into commit 53dba9e212cc3f440acc60a8d333df3967931937
    ("Initial patch commit + compilation fixes").
