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.
