I have Fedora 27 installed on my laptop with an older AMD CPU (AMD Turion X2 mobile processor RM-75 / 2.2 GHz). The following error message appears every time I boot:

Spectre V2: Spectre mitigation: LFENCE not serializing, switching to generic retpoline

Can I just set generic retpoline as default? Thanks!
