In commit eb631bb5bf5b ("arm64: Support arch_irq_work_raise() via self IPIs") a new function "arch_irq_work_raise" was added without a prototype in header irq_work.h
In commit d914d4d49745 ("arm64: Implement panic_smp_self_stop()") a new function "panic_smp_self_stop" was added without a prototype in header irq_work.h
We get the following warnings on W=1: arch/arm64/kernel/smp.c:842:6: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes] arch/arm64/kernel/smp.c:862:6: warning: no previous prototype for ‘panic_smp_self_stop’ [-Wmissing-prototypes]
Fix the same by adding the missing prototype in header irq_work.h
