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.
