  Modified files:
    sys/kern             kern_intr.c 
  Log:
  Adjust the interrupt storm handling code to better handle a storm.  When
  a storm is detected, enter "storming" mode which throttles the interrupt
  source such that the handlers are run once every clock tick.  Previously
  we allowed a full set of storm_threshold interations through the handler
  before going back to sleep.  Also, this currently will intentionally exit
  storming mode once a second to see if the storm has passed.
