   Detect physical memory addressing limit

   x64 processors have different physical memory addressing limits. For   
   example, early Intel CPU models only have 40-bit of physical memory   
   addressing (64GB), and then 46-bit on later models (64TB). AMD models have   
   40-bit (1TB), then 48-bit (256TB).   
      
   Assuming that a system has 64GB of RAM and with an Intel CPU, is there a way   
   to detect whether the CPU has 40-bits or 46-bits physical memory addressing   
   limit?
