Subject: [PATCH] parisc: add sysctl file interface panic_on_stackoverflow
The variable sysctl_panic_on_stackoverflow is used in
arch/parisc/kernel/irq.c and arch/x86/kernel/irq_32.c, but the sysctl file
interface panic_on_stackoverflow only exists on x86.
Add sysctl file interface panic_on_stackoverflow for parisc
