Several architectures define arch_irq_work_raise, and kernel/irq_work.c defines a __weak version for architectures that do not. However, nothing ever prototypes this function, leading to warnings from GCC and Sparse like this:
kernel/irq_work.c:52:28: warning: no previous prototype for ‘arch_irq_work_raise’ [-Wmissing-prototypes] Add a prototype for this function in linux/irq_work.h. In addition to eliminating the warnings, this also ensures that the types for all versions of the function will stay in sync.
