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.
