arm64: Introduce retpoline for aarch64/arm64.linux-4.16.5-amp
This patch adds retpoline support for aarch64.
This includes:
* Kconfig flag CONFIG_RETPOLINE to enable it
* testing for required compiler support
* generation of external retpoline thunk functions
* patches for the arm64 specific assembly code
* Enable /sys/devices/system/cpu/vulnerabilities
* arm64: retpoline: Use kernel's EXPORT_SYMBOL macro.
* arm64: retpoline: Add thunks for x29 and x30.
* arm64: retpoline: Add function signature for symbol versioning.
