changeset b4e30b30f695 in /z/repo/m5
details: http://repo.m5sim.org/m5?cmd=changeset;node=b4e30b30f695
description:
InOrder didnt have all it's params set to a default value, which is now
required for M5 objects; Also, a # of values need to be reset to 0 (or the
appropriate value) before we assume they are OK for use.
