    sys/i386/i386        mplock.s swtch.s 
  Log:
  Eliminate frequent silo overflows by restoring the TEST_LOPRIO code.
  This code was eliminated when the PEND_INTS algorithm was added.  But it was
  discovered that PEND_INTS only worsen latency for FAST_INTR() routines,
  which can't be marked pending.
