Use 4Kb for kernel stacks instead of 8Kb found in arch/sh/Kconfig.debug

The configuration item CONFIG_4KSTACKS:

• prompt: Use 4Kb for kernel stacks instead of 8Kb
• type: bool
• depends on: CONFIG_DEBUG_KERNEL && ( CONFIG_MMU || CONFIG_BROKEN ) && ! CONFIG_PAGE_SIZE_64KB
• defined in arch/sh/Kconfig.debug
• found in Linux kernels: 2.6.19–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD

If you say Y here the kernel will use a 4Kb stacksize for the kernel stack attached to each process/thread. This facilitates running more threads on a system and also reduces the pressure on the VM subsystem for higher order allocations. This option will also use IRQ stacks to compensate for the reduced stackspace.
