Marco Nelissen 80fc836f3e filemap: avoid truncating 64-bit offset to 32 bits
commit f505e6c91e7a22d10316665a86d79f84d9f0ba76 upstream.

On 32-bit kernels, folio_seek_hole_data() was inadvertently truncating a
64-bit value to 32 bits, leading to a possible infinite loop when writing
to an xfs filesystem.
