  Modified files:
    sys/dev/ppbus        pps.c 
  Log:
  Make the pps interrupt register as MPSAFE and FAST.  Use a spin lock
  to syncrhonize access to the data as a result.  This makes the pps
  less likely to miss the 1ms pulse that I'm feeding it, but not
  entirely reliable yet on my 133MHz P5.
