    sys/ia64/ia64        interrupt.c nexus.c sapic.c 
    sys/ia64/include     intr.h md_var.h sapicvar.h 
  Log:
  Rework the interrupt code and add support for interrupt filtering
  (INTR_FILTER). This includes:
  o  Save a pointer to the sapic structure and IRQ for every vector,
     so that we can quickly EOI, mask and unmask the interrupt.
  o  Add locking to the sapic code now that we can reprogram a
     sapic on multiple CPUs at the same time.
  o  Use u_int for the vector and IRQ. We only have 256 vectors, so
     using a 64-bit type for it is rather excessive.
  o  Properly handle concurrent registration of a handler for the
     same vector.
  
  Since vectors have a corresponding priority, we should not map
  IRQs to vectors in a linear fashion, but rather pick a vector
  that has a priority in line with the interrupt type. This is left
  for later. The vector/IRQ interchange has been untangled as much
  as possible to make this easier.
