[IA64] /proc/cpuinfo "physical id" field cleanups
Clean up the process for presenting the "physical id" field in /proc/cpuinfo. - remove global smp_num_cpucores, as it is mostly useless - remove check_for_logical_procs(), since we do the same functionality in identify_siblings() - reflow logic in identify_siblings(). If an older CPU does not implement PAL_LOGICAL_TO_PHYSICAL, we may still be able to get useful information from SAL_PHYSICAL_ID_INFO - in identify_siblings(), threads/cores are a property of the CPU, not the platform - remove useless printk's about multi-core / thread capability in identify_siblings(), as that information is readily available in /proc/cpuinfo, and printing for the BSP only adds little value - smp_num_siblings is now meaningful if any CPU in the system supports threads, not just the BSP - expose "physical id" field, even on CPUs that are not multi-core / multi-threaded (as long as we have a valid value). Now we know what sockets Madisons live in too. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
