REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2329 XD (ExecutionDisable) feature, when turned on, allows page table entry BIT63 set to 1 indicating the memory pointed by the page table is disallowed to execute. DxeIpl::CreateIdentityMappingPageTables() enables the XD when CPU supports it. Later DxeCore modifies the page table to set the BIT63 to protect the stack/heap to disallow code execution in stack/heap. UefiCpuPkg/CpuCommonFeaturesLib enables/disables the XD feature according to PcdCpuFeaturesSetting. When XD is disabled, GP fault is generated immediately because some page entries have BIT63 set. To fix this issue, this patch removes the XD feature logic from UefiCpuPkg/CpuCommonFeaturesLib so the XD feature is only taken care of by DxeIpl.
