Follow this thread: https://lore.kernel.org/r/CANpbe9Wm3z8fy9HbgS8cuhoj0TREYEEkBipDuhgkWFvqX0UoVQ@mail.gmail.com People booting latest kernel on 486 without CPUID support. I can't find it in me to care for that old rust and yet I did it again. :-\ So yeah, +1 for removing old code which ain't worth maintaining. There's stable and older kernels, those folks can use those and that's it. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
