5 Like all other architectures, x86_64 has a kernel stack for every
8 zombie. While the thread is in user space the kernel stack is empty
12 associated with each CPU.  These stacks are only used while the kernel
20   kernel switches from the current task to the interrupt stack.  Like
22   for kernel interrupt processing without having to increase the size
27 Switching to the kernel interrupt stack is done by software based on a
51 NMI.  arch/x86_64/kernel/entry.S::paranoidentry adjusts the stack
71   when the kernel is very confused (e.g. kernel stack pointer corrupt).
72   Using a separate stack allows the kernel to recover from it well enough
79   NMI can be delivered at any time, including when the kernel is in the
81   assumptions about the previous state of the kernel stack.
88   When debugging a kernel, debug interrupts (both hardware and
