| after following patch,

|     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?
