    [IA64] New IA64 core/thread detection patch · 4129a953
    Fenghua Yu authored
    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.
