CONFIG_IRQSTACKS: Use separate kernel stacks when processing interrupts

General informations

The Linux kernel configuration item CONFIG_IRQSTACKS has multiple definitions:

Use separate kernel stacks when processing interrupts found in arch/sh/Kconfig.debug

The configuration item CONFIG_IRQSTACKS:

• prompt: Use separate kernel stacks when processing interrupts
• type: bool
• depends on: CONFIG_DEBUG_KERNEL && CONFIG_BROKEN
• defined in arch/sh/Kconfig.debug
• found in Linux kernels: 2.6.24–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

If you say Y here the kernel will use separate kernel stacks for handling hard and soft interrupts. This can help avoid overflowing the process kernel stacks.
