Marcel Moolenaar 7c9eed5c4e Change region 4 to be part of the kernel. This serves 2 purposes:
1.  The PBVM is in region 4, so if we want to make use of it, we
    need region 4 freed up.
2.  Region 4 and above cannot be represented by an off_t by virtue
    of that type being signed. This is problematic for truss(1),
    ktrace(1) and other such programs.
