As mentioned for prior versions of this, this commit message does not
make any sense with the current state of SPL stack used.

This does not change the TPL stack to match SPL stack, it only moves it
to make room for a 256-byte bloblist used by VBE/VPL.

Please update the commit message and subject to reflect the reason for
this change.

Regards,
Jonas
