-All interrupt-gate descriptors which switch to a new stack with the `IST` are initialized with the `set_intr_gate_ist` function. For example:
+All interrupt-gate descriptors, which switch to a new stack with the `IST`, are initialized within the `idt_setup_from_table` function. That function initializes every gate descriptor within the `struct idt_data def_idts[]` array.
+For example:
 
 ```C
-set_intr_gate_ist(X86_TRAP_NMI, &nmi, NMI_STACK);
-...
-...
-...
-set_intr_gate_ist(X86_TRAP_DF, &double_fault, DOUBLEFAULT_STACK);
-```
-
-where `&nmi` and `&double_fault` are addresses of the entries to the given interrupt handlers:
-
-```C
-asmlinkage void nmi(void);
-asmlinkage void double_fault(void);
+static const __initconst struct idt_data def_idts[] = {
+    ...
+	INTG(X86_TRAP_NMI,		nmi),
+    ...
+	INTG(X86_TRAP_DF,		double_fault),

 When an interrupt or an exception occurs, the new `ss` selector is forced to `NULL` and the `ss` selector’s `rpl` field is set to the new `cpl`. The old `ss`, `rsp`, register flags, `cs`, `rip` are pushed onto the new stack. In 64-bit mode, the size of interrupt stack-frame pushes is fixed at 8-bytes, so that we will get the following stack:
