Will add some 'fake' features to the list, and make more tests.

This is a 2-socket E5-2699v4 CPU(22 core with CAT/CMT enabled and CDP disabled) system, as you said, the cache monitor capability is printed more than once. And I need to point out that the following cache 'control' element is also printed for twice, it met the same situation you mentioned for cache monitor. "<control granularity='2816' unit='KiB' type='both' maxAllocs='16'/>" After you have read my considerations(in the reply to your review of patch 2) for reason why I used current disign, if you still think it not wise to make it duplicated, let's find a proper place to keep the data and eliminate such kind of duplication. We can make any changes to make our design more reasonable in the design stage. Thanks for your kind revew!
