Ok I suspect that this is a problem with the build. I would guess that
the files bcopyinout.o fusu.o bcopystr.o were not recompiled following the
recent changes I made to vmparam.h. These changes increased the size of
the kernel VM data area and unless these files are recompiled various
accesses to the kernel data area will be prevented as they will be using
the old size. i.e. copyin, copyout etc will return EFAULT.
