4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Guenter Roeck <linux@xxxxxxxxxxxx> In linux-4.4.y, the definition of X86_FEATURE_RETPOLINE and X86_FEATURE_RETPOLINE_AMD is different from the upstream definition. Result is an overlap with the newly introduced X86_FEATURE_L1TF_PTEINV. Update RETPOLINE definitions to match upstream definitions to improve alignment with upstream code.
