ext4: fix data offset overflow in ext4_xattr_fiemap() on 32-bit archs
commit a60697f411eb365fb09e639e6f183fe33d1eb796 upstream.
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.
