Subject: [PATCH 42/46] kernel: Add prototype declaration to appropriate
 header file include/linux/sched.h

Add prototype declaration of function to header file
include/linux/sched.h
because it used by more than one file.

This eliminates the following warning in kernel/sched/core.c:
kernel/sched/core.c:2822:25: warning: no previous prototype for ‘preempt_schedule_irq’ [-Wmissing-prototypes]
