The prototype was hidden on x86, which causes a warning:

What do you mean by "hidden on x86"?

arch_irq_work_raise() was declared on 7 architectures,
including x86.

I meant hidden in some configurations. Specifically, x86
only declares the function when it overrides it for
CONFIG_X86_LOCAL_APIC, while without that option the generic
stub still gets compiled but is never declared.
