Modified Files:
src/sys/rump/librump/rumpkern: lwproc.c
Log Message:
Explicitly zerofill some fields which are not within the boundaries
of p_start/endzero for whatever reasons.
Obviously, this fixes remote physio when running with MALLOC_OPTIONS J.
Otherwise PS_WEXIT is set in struct proc, proc_vmspace_getref() fails,
and copyout_proc() with it.
