Log Message: ----------- Replace ARC cache management algorithm with the similar but slightly simpler 2Q algorithm, to avoid possible problems with the pending patent on ARC. Testing so far suggests that there is little if any performance loss from doing this. Note that this patch is going into the 8.0 branch only; a much more extensive revision is planned for HEAD.
