  Modified files:
    sys/powerpc/include  critical.h 
  Log:
  Remove race condition between reading of MSR, setting md_savecrit,
  and setting MSR. This was most evident with the idle proc running
  with interrupts disabled and causing a lockup. Switch over to the
  i386 style which does things in the right order.
  
  debug assisted by:  gallatin, and the invaluable KTR option.
