drochner	8c0a9bab00	Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many architectures), truncate them intelligently instead. The truncation is done centralized in vnode_pager.c. This prevents from wrap-over effects when parts of large (>2^32 byte) files are mmapped. Don't allow to mmap above the numerical range of vm_offset_t. This is considered a temporary solution until the vm system handles the object sizes/offsets more cleanly.	1997-07-04 20:22:09 +00:00
