The infrastructure to handle x86 interrupts.

idt_register_T - struct [packed]

This struct is very similar to gdt_descriptor_T. It holds the size and address of the Table, where the interrupt handlers are looked up.

idt_descriptor_entry_T - struct

This struct stores information about one interrupt handler. The osdev wiki explains this more detailed.

g_idt_register - global variable

The default IDT configuration loaded when the IDT gets initialized.

g_handling_interrupt - global variable

When the system isn't handling an interrupt this is set to 0. If this is greater than 0 the system is currently handling an interrupt,

idt_init() - function (void)

This function fills all the interrupt gates (handlers) into the IDT and loads it.
