{   The purpose of this request is to advise the OS that
{ access to a portion of memory is finished (for a while) and
{ that access to a different portion of memory is intended.
{ This request is functionally equivalent to MMP$ADVISE_OUT
{ followed by a MMP$ADVISE_IN, both which has less overhead.
{
{       MMP$ADVISE_OUT_IN (OUT_PVA, OUT_LENGTH, IN_PVA,
{         IN_LENGTH, STATUS)
{
{ OUT_PVA: (input) This parameter specifies the start
{       of memory to be advised out.
{
{ OUT_LENGTH: (input) This parameter specifies the number of
{       of bytes to be advised out.
{
{ IN_PVA: (input) This parameter specifies the start of
{       the range of memory to be advised in.
{
{ IN_LENGTH: (input) This parameter specifies the number of
{       bytes to be advised in.
{
{ STATUS: (output) This parameter specifies the request status.
{       The possible error codes are:
