From 0cb333b58879d5239e1cba8a3c21a5e621fe3013 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 17 Aug 2018 12:01:36 +0200 Subject: [PATCH] x86/mce: Add notifier_block forward declaration Without linux/irq.h, there is no declaration of notifier_block, leading to a build warning: In file included from arch/x86/kernel/cpu/mcheck/threshold.c:10: arch/x86/include/asm/mce.h:151:46: error: 'struct notifier_block' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] It's sufficient to declare the struct tag here, which avoids pulling in more header files.
