Subject: [PATCH] parisc: add sysctl file interface panic_on_stackoverflow
Date: Sat, 11 Apr 2020 21:06:19 +0800 [thread overview]
Message-ID: <1586610379-51745-1-git-send-email-nixiaoming@huawei.com> (raw)
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.
