  MFC r204903:
  
  Place interrupt handling in a critical section and remove double
  counting in incrementing the interrupt nesting level. This fixes a number
  of bugs in which the interrupt thread could be preempted by an IPI,
  indefinitely delaying acknowledgement of the interrupt to the PIC, causing
  interrupt starvation and hangs.
