C++ (Cpp) _nmask_and_or_msr Examples

Example #1

	 * when going to sleep.  This is necessary even with
	 * RTLinux since we are not guaranteed an interrupt
	 * didn't come in and is waiting for a __sti() before
	 * emulating one.  This way, we really do hard disable.
	 *
	 * We assume that we're sti-ed when we come in here.  We
	 * are in the idle loop so if we're cli-ed then it's a bug
	 * anyway.
