It adds two new fields "core id" and "cpu cores" to x86 /proc/cpuinfo and the "core id" field for x86_64("cpu cores" field is already present in x86_64). Number of processor cores in a die is detected using cpuid(4) and this is documented in IA-32 Intel Architecture Software Developer's Manual (vol 2a) (http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a) This patch also adds cpu_core_map similar to cpu_sibling_map.
