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.
