If you've read the previous parts, you can remember that the earliest place in the Linux kernel `x86_64` architecture-specific source code which is related to the interrupt is located in the [arch/x86/boot/pm.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/pm.c) source code file and represents the first setup of the [Interrupt Descriptor Table](http://en.wikipedia.org/wiki/Interrupt_descriptor_table). It occurs right before the transition into the [protected mode](http://en.wikipedia.org/wiki/Protected_mode) in the `go_to_protected_mode` function by the call of the `setup_idt`: If you've read the previous parts, you can remember that the earliest place in the Linux kernel `x86_64` architecture-specific source code which is related to the interrupt is located in the [arch/x86/boot/pm.c](https://github.com/torvalds/linux/blob/16f73eb02d7e1765ccab3d2018e0bd98eb93d973/arch/x86/boot/pm.c) source code file and represents the first setup of the [Interrupt Descriptor Table](http://en.wikipedia.org/wiki/Interrupt_descriptor_table).
