The patch does not change any code behavior but only refactors by: * replaces the hardcode 0x80000000 with CPUID_EXTENDED_FUNCTION * replaces the hardcode 0x80000008 with CPUID_VIR_PHY_ADDRESS_SIZE * replace "UINT32 Eax" with "CPUID_VIR_PHY_ADDRESS_SIZE_EAX VirPhyAddressSize" Signed-off-by: Ray Ni <ray.ni@intel.com> Cc: Eric Dong <eric.dong@intel.com> Cc: Rahul Kumar <rahul1.kumar@intel.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Michael D Kinney <michael.d.kinney@intel.com> Cc: Ahmad Anadani <ahmad.anadani@intel.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Michael D Kinney <michael.d.kinney@intel.com>
