Subject: [PATCH 50/58] x86: arch/x86/kernel/irq_work.c: Add prototype for smp_irq_work_interrupt

arch/x86/kernel/irq_work.c defines a function smp_irq_work_interrupt,
only called from assembly.  Add a prototype right before its definition,
to satisfy GCC (-Wmissing-prototypes) and Sparse (-Wdecl).

arch/x86/kernel/irq_work.c:12:6: warning: no previous prototype for ‘smp_irq_work_interrupt’ [-Wmissing-prototypes]
