[IA64] multi-core/multi-thread identification
Version 3 - rediffed to apply on top of Ashok's hotplug cpu patch. /proc/cpuinfo output in step with x86. This is an updated MC/MT identification patch based on the previous discussions on list. Add the Multi-core and Multi-threading detection for IPF. - Add new core and threading related fields in /proc/cpuinfo. Physical id Core id Thread id Siblings - setup the cpu_core_map and cpu_sibling_map appropriately - Handles Hot plug CPU Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Gordon Jin <gordon.jin@intel.com> Signed-off-by: Rohit Seth <rohit.seth@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
