    [IA64] /proc/cpuinfo "physical id" field cleanups · 113134fc
    Alex Chiang authored
    Clean up the process for presenting the "physical id" field in
    	- 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.
