Remove special L2 cache case for Knights Landing
L2 cache is shared by 2 cores on Knights Landing, which has 4 threads per core: https://en.wikipedia.org/wiki/Xeon_Phi#Knights_Landing So L2 cache is shared by 8 threads on Knights Landing as reported by CPUID. We should remove special L2 cache case for Knights Landing. [BZ #18185] * sysdeps/x86/cacheinfo.c (init_cacheinfo): Don't limit threads sharing L2 cache to 2 for Knights Landing.
