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
