    sys/i386/i386        support.s 
  Log:
  Fix a problem where we were switching npxproc from underneath processes
  running in process context in order to run interrupt handlers.  This
  caused a big smashing of the stack on AMD K6, K5 and Intel Pentium (ie, P5)
  processors because we are using npxproc as a flag to indicate whether
  the state has been pushed onto the stack.
