Subject[PATCH 39/46] kernel: Add prototype declaration to header file include/linux/irq_work.h
Add prototype declaration of function to header file
include/linux/irq_work.h because it is used by more than one file.

This eliminates the following warning in kernel/irq_work.c:
kernel/irq_work.c:51:13: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes]
