  ia64 work.
  
  ivt.S:
  Detect userspace stack in heavyweight handler and switch to kernel stack.
  Remember the old stack pointer.
  As for register stack, kernel stack is assumed still.
  Fix alignment issues that showed when STACK_ITEMS was odd.
  Fix ld8 instruction that did subtraction of 8 instead of addition of 8.
  
  scheduler.c:
  Change before_thread_runs_arch() to calculate address of top of the stack
  for the interrupt handler.
