    sys/sparc64/sparc64  machdep.c 
  Log:
  Close a race I introduced in the spinlock_* changes.  We need to finish
  disabling interrupts before updating the saved pil in the thread.  If we
  save the value first then it can be clobbered if an interrupt comes in
  and the interrupt handler tries to acquire a spin lock.
