Provide functions for moving page tables upwards.
Now that we're initializing the temporary stack location to
STACK_TOP_MAX, do we still need move_page_tables_up() for variable
length argument support?  I originally added it into shift_arg_pages()
to support 32-bit apps exec'ing 64-bit apps when we were using
TASK_SIZE as our temporary location.

Maybe we should decouple this patch from the others and submit it as
an enhancement to support memory defragmentation.
