Log Message:
This file is a replicant of hp300.  The following is peculair to
the original HPBSD implementation and HP hardware design.

 * Portions of the last segment of KVA space (0xFFF00000 -
 * 0xFFFFFFFF) are mapped for a couple of purposes.  0xFFF00000
 * for UPAGES is used for mapping the current process u-area
 * (u + kernel stack).  The very last page (0xFFFFF000) is mapped
 * to the last physical page of RAM to give us a region in which
 * PA == VA.  We use the first part of this page for enabling
 * and disabling mapping.  The last part of this page also contains
 * info left by the boot ROM.

Nuke lptpa because that is irrelavant for LUNA.
Put #if defined(M68040) for consistency postponing efforts of LUNA-2.
