Alex Shi 901b04450a x86/numa: Improve internode cache alignment ... Currently cache alignment among nodes in the kernel is still 128 bytes on x86 NUMA machines - we got that X86_INTERNODE_CACHE_SHIFT default from old P4 processors. But now most modern x86 CPUs use the same size: 64 bytes from L1 to last level L3. so let's remove the incorrect setting, and directly use the L1 cache size to do SMP cache line alignment. This patch saves some memory space on kernel data, and it also improves the cache locality of kernel data. The System.map is quite different with/without this change: before patch after patch ... 000000000000b000 d tlb_vector_| 000000000000b000 d tlb_vector 000000000000b080 d cpu_loops_p| 000000000000b040 d cpu_loops_ ...
