    x86: apic - generic_processor_info

    - use physid_set instead of phys_cpu and physids_or
    - set phys_cpu_present_map bit AFTER check for allowed
      number of processors
    - add checking for APIC valid version in 64bit mode
      (mostly not needed but added for merging purpose)
    - add apic_version definition for 64bit mode which
      is used now

we are getting warning for acpi path on 64 bit system

please add #ifdef for that.
actually, 64 bit doesn't use that apic_version[]


or using following patch?
