30   the split thread and interrupt stacks on i386, this gives more room
31   for kernel interrupt processing without having to increase the size
34   The interrupt stack is also used when processing a softirq.
36 Switching to the kernel interrupt stack is done by software based on a
37 per CPU interrupt nest counter. This is needed because x86-64 "IST"
43 events on x86_64.  This feature is called the Interrupt Stack Table
49 interrupt-gate descriptor.  When an interrupt occurs and the hardware
51 pointer based on the IST value, then invokes the interrupt handler.  If
52 the interrupt came from user mode, then the interrupt handler prologue
