[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
