4.14-stable review patch. If anyone has any objections, please let me know.

[ 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.
Fixes: 447ae3166702 ("x86: Don't include linux/irq.h from asm/hardirq.h")
