Description of problem:
losetup supports large file but can't be use with very big offset.
it seems the offset is an int, but it should be a long int (I haven't
check the source)

Version-Release number of selected component (if applicable):
losetup-2.12-18

How reproducible:
Always

Steps to Reproduce:
losetup -o 8315758080 /dev/loop0 /dev/hde
dd if=/dev/loop0 of=dd_1 count=1
losetup -d /dev/loop0
losetup -o 4294967295 /dev/loop0 /dev/hde
dd if=/dev/loop0 of=dd_2 count=1
diff dd_1 dd_2

Actual Results:  offset wraps on 32 bits

Expected Results:  64 bits offset should be handle
