Subject: [PATCH] ext4: fix data offset overflow in ext4_xattr_fiemap() on
 32-bit archs

On 32-bit architectures with 32-bit sector_t computation of data offset
in ext4_xattr_fiemap() can overflow resulting in reporting bogus data
location. Fix the problem by typing block number to proper type before
shifting.
