IPF SDM 2.2 changes definition of PAL_LOGICAL_TO_PHYSICAL to add proc_number=-1 to get core/thread mapping info on the running processer. Based on this change, we had better to update existing core/thread detection in IA64 kernel correspondingly. The attached patch implements this change. It simplifies detection code and eliminates potential race condition. It also runs a bit faster and has better scalability especially when cores and threads number grows up in one package.
