  Log:
  Add interrupt counters for IPIs.  By default they are disabled, but they
  can be enabled by enabling COUNT_IPIS in smptests.h.  When enabled, each
  CPU provides an interrupt counter for nearly all of the IPIs it receives
  (IPI_STOP currently doesn't have a counter) that can be examined using
  vmstat -i, etc.
