This option will slow down process creation somewhat.

+ ---help---
+ Say Y to verify that the per_cpu map being accessed has
+ been setup. Adds a fair amount of code to kernel memory
+ and decreases performance.

+ Say N if unsure.

-config IRQSTACKS
- bool "Use separate kernel stacks when processing interrupts"
- help
- 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.

bool "Expose hardware/virtual IRQ mapping via debugfs"
