  Modified files:
    sys/ia64/ia64        exception.S interrupt.c 
    sys/ia64/include     md_var.h 
  Log:
  Keep interrupts disabled while handling external interrupts.
  There's no advantage in allowing nested external interrupts.
  In fact, it leads to a potential stack overrun.
  
  While here, put the interrupt vector in the trapframe, so as
  to compensate for the 36 cycle latency of reading cr.ivr.
  
  Further simplify assembly code by dealing with ASTs from C.
