[EN] Mitigate Spectre V2 Vulnerabilities

[Teriarch]

In kernel release 6.9.3-1-siduction-amd64 the configuration option

CONFIG_MITIGATION_RETPOLINE=y

is missing (it reads "# CONFIG_MITIGATION_RETPOLINE is not set" instead).

I wonder whether it be possible to enable the option for the next release. It allows for mitigation
esp. for older processors and removes the kernel message

      Spectre V2 : Kernel not compiled with retpoline; no mitigation available!
      Spectre V2 : Vulnerable

Thx in advance
