AS you can see it has only one difference in the name of the array of the interrupts handlers entry points. Now it is `early_idt_handler_arry`:

It fills `early_idt_handler_arry` with the `.rept NUM_EXCEPTION_VECTORS` and contains entry of the `early_make_pgtable` interrupt handler (more about its implementation you can read in the part about [Early interrupt and exception handling](https://0xax.gitbooks.io/linux-insides/content/Initialization/linux-initialization-2.html)). For now we come to the end of the `x86_64` architecture-specific code and the next part is the generic kernel code. Of course you already can know that we will return to the architecture-specific code in the `setup_arch` function and other places, but this is the end of the `x86_64` early code.
