  Modified files:
    sys/compat/ndis      kern_ndis.c ntoskrnl_var.h subr_hal.c 
                         subr_ndis.c subr_ntoskrnl.c 
  Log:
  - Use memory barrier with atomic operations in ntoskrnl_lock_dpc() and
    ntoskrnl_unlocl_dpc().
  - hal_raise_irql(), hal_lower_irql() and hal_irql() didn't work right
    on SMP (priority inheritance makes things... interesting). For now,
    use only two states: DISPATCH_LEVEL (PI_REALTIME) and PASSIVE_LEVEL
    (everything else). Tested on a dual PIII box.
  - Use ndis_thsuspend() in ndis_sleep() instead of tsleep(). (I added
    ndis_thsuspend() and ndis_thresume() to replace kthread_suspend()
    and kthread_resume(); the former will preserve a thread's priority
    when it wakes up, the latter will not.)
  - Change use of tsleep() in ndis_stop_thread() to prevent priority
    change on wakeup.
