Limit threads sharing L2 cache to 2 for SLM/KNL
Silvermont and Knights Landing have a modular system design with two cores sharing an L2 cache. If more than 2 cores are detected to shared L2 cache, it should be adjusted for Silvermont and Knights Landing. [BZ #18185] * sysdeps/x86_64/cacheinfo.c (init_cacheinfo): Limit threads sharing L2 cache to 2 for Silvermont/Knights Landing.
