[ Upstream commit 704ae091b061082b37a9968621af4c290c641d50 ]
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.
