i thought to keep the stub so could add more other stuff in the switch
like 64 bit

        clear_cpu_cap(c, X86_FEATURE_PAT);

        switch (c->x86_vendor) {
        case X86_VENDOR_AMD:
                early_init_amd(c);
                if (c->x86 >= 0xf && c->x86 <= 0x11)
                        set_cpu_cap(c, X86_FEATURE_PAT);
                break;
        case X86_VENDOR_INTEL:
                early_init_intel(c);
                if (c->x86 == 0xF || (c->x86 == 6 && c->x86_model >= 15))
                        set_cpu_cap(c, X86_FEATURE_PAT);
                break;
        case X86_VENDOR_CENTAUR:
                early_init_centaur(c);
                break;
        }
