Great! I didn't know that we now have another platform where the stack
grows upwards! Now we are not alone in this regard!
Anyway, the suggested & untested patch below should fix the metag arch
to cope which my changes to fs/exec.c (unless the metag people want to
implement proper stack randomization too). Either I can push it via the
parisc tree, or you can take it via the metag tree. Please let me know.
