Ah I see. Well in my case it's no old P4 heater but a not that ancient T2400 Intel Core Duo with 31W TDP. ;)

But good to hear I would not need CONFIG_MITIGATION_RETHUNK anyhow? If that's the case depending on !X86_32 would make sense. Don't know whether the 32bit Intel Atoms (the only 'recent' X86_32 CPU left besides the Core Duo) would need this mitigation.
