The type represents byte offset in the vm_object_t data space, which does not span negative offsets in FreeBSD VM. The change matches byte offset signess with the unsignedness of the vm_pindex_t which represents the type of the page indexes in the objects. This allows to remove the UOFF_TO_IDX() macro which was used when we have to forcibly interpret the type as unsigned anyway. Also it fixes a lot of implicit bugs in the device drivers d_mmap methods.
