David Greenman 5f55e84104 Accessing pages beyond the end of a mapped file results in internal ... inconsistencies in the VM system that eventually lead to a panic. These changes fix the behavior to conform to the behavior in SunOS, which is to deny faults to pages beyond the EOF (returning SIGBUS). Internally, this is implemented by requiring faults to be within the object size boundaries. These changes exposed another bug, namely that passing in an offset to mmap when trying to map an unnamed anonymous region also results in internal inconsistencies. In this case, the offset is forced to zero. Reviewed by: John Dyson and others		1995-05-18 02:59:26 +00:00
